Nightingale – open-source karaoke app that works with any song on your computer

I've been working on a karaoke app called Nightingale. You point it at your music folder and it turns your songs into karaoke - separates vocals from instrumentals, generates word-level synced lyrics, and lets you sing with highlighted lyrics and pitch scoring. Works with video files too.

Everything runs locally on your machine, nothing gets uploaded. No accounts, no subscriptions, no telemetry.

It ships as a single binary for Linux, macOS, and Windows. On first launch it sets up its own isolated Python environment and downloads the ML models it needs - no manual installation of dependencies required.

My two biggest drivers for the creation of this were:

    The lack of karaoke coverage for niche, avant-garde, and local tracks.

    Nostalgia for the good old cheesy karaoke backgrounds with flowing rivers, city panoramas, etc.

Some highlights:

    Stem separation using the UVR Karaoke model (preserves backing vocals) or Demucs

    Automatic lyrics via WhisperX transcription, or fetched from LRCLIB when available

    Pitch scoring with player profiles and scoreboards

    Gamepad support and TV-friendly UI scaling for party setups

    GPU acceleration on NVIDIA (CUDA) and Apple Silicon (CoreML/MPS)

    Built with Rust and the Bevy engine

The whole stack is open source. No premium tier, no "open core" - just the app.

Feedback and contributions welcome.

This looks like awesome awesome fun! Will let you know how it runs. What a wonderful idea <3

solstice• 4 months ago

Excited to try this out. How well does WhisperX deal with lyrics in say Mandarin or Cantonese? Does it output Hanzi?

rzzzzru27• 4 months ago

I haven't tried Mandarin and Cantonese, but tried Japanese. back at that time, it performed poorly. however, I've tweaked a bunch of settings since then, so maybe it has changed. Hanzi is a supported font and can be output, but the transcript/alignment quality might not be the best

Struggled somewhat with Tjamuku Ngurra by the Tjintu Desert Band, absolutely nailed Mariah Carey's Ken Lee.

Just tried it with B.E.D - Walk Away[0], unfortunately it lost track of the lyrics after 30 secs (Model is "large-v3"). Will play around a bit more, as it would be great to have a working karaoke generator.

Some quick feedback:

  - Needs a way to skip for-/backwards during playback to validate the result
  - Sentences seem to be recognized (first letter has uppercasing), but periods aren't added
  - Needs an option to edit results from the track analysis

Thanks for keeping it FOSS!

Periods in song lyrics?

rzzzzru27• 4 months ago

hey mate! thanks for your feedback.

indeed, I'm running to two problems on the analyzer side: 1. align model sliding off (especially w/ chorus/back vocals present) 2. transcript skipping parts of lyrics in lyrics-heavy tracks (I tried a lot of russian rap, lol)

happy for contributions as I'm not that experienced w/ machine learning side of the project, mostly it was emperical "tweak the parameters and look what is changed"

evanjrowley• 4 months ago

Amazing work! I am thrilled someone was motivated to approach this problem and develop a creative solution like this. There are very limited options for Karaoke, especially in the FOSS space. Most Karaoke apps are super limited and that's driven many Karaoke enjoyers I know to YouTube in search of the songs they want to sing. This solution would give them the power to do even more songs, even better than what's out there now!

Questions for you:

1. What CUDA capability level is necessary for Nvidia GPU accelleration to work?

3. Are there any plans to support iGPU/NPU accelleration on AMD and Intel? Asking because those chips are most common in the mini computers sold at low cost these days.

My family members who love Karaoke and will be happy to try this. Looking forward to it!

QuantumNoodle• 4 months ago

I studied signal processing in university and my career evolved to not use what I studied. Decades ago, giving an algorithm a sound file and isolating tracks was difficult.

How does your implementation accomplish this? Were you involved or did you use something off the shelf?

Edit: ah, using neural nets, demucs. I wonder if there is pure math approach that can compete?

djmips• 4 months ago

Can you bypass the LRCLIB lookup and always use Whisper?

app that works with any song on your computer

Impressive, very nice. Now let's see my death metal collection.

Just joking! Very nice, thanks for open-sourcing it.

rzzzzru27• 4 months ago

No joke, feel free to try it! The beauty of the approach is that you don't have any limitations. Just be prepared to degraded experience, sometimes models struggle even with the simplest pop tracks :D

caipira• 4 months ago

This looks amazing! looking forward to test it on the weekend. Does it work well on a raspberry pi with 4 gigs of ram?

rzzzzru27• 4 months ago

oof, since it uses quite heavy models locally I would expect it to struggle on such hardware. M1+ macs & nvidia gpus work the best and fastest.

dmd2• 4 months ago

This looks great, but I don't understand what it's supposed to do. I assumed the idea was "remove the lyrics" but of the 5 songs I tried (from Cry Cry Cry, Indigo Girls, and Suzanne Vega), none seemed to have any change from the original at all - it's showing the words on the screen (and the timing is perfect) but it's not removing the singing at all. How do you turn off the singing?

rzzzzru27• 4 months ago

hey!

you can use + / - buttons on the keyboard to change the level of guidance according to your preference, generally there is a controls legend in the top right corner

https://nightingale.cafe/docs/controls

dmd2• 4 months ago

Yeah, I did that. I think the problem is when there are multiple singers harmonizing it only removes one.

mynameajeff2• 4 months ago

My wife is a huge karaoke fan. I'm especially interested in the pitch scoring since we usually play the karaoke games on older consoles for that exact feature. Nobody really makes games like that anymore without a subscription (and most of these good modern karaoke platforms are exclusive to east asia anyways). If this works well this could make for some really fun social events, looking forward to trying this.

rzzzzru27• 4 months ago

please try it out and share your feedback afterwards!

both transcript/alignment might not work perfectly, but it really depends on the song

echoangle• 4 months ago

I don’t want to take away from OPs project (which seems really nice) but have you tried Ultrastar Deluxe ( https://usdx.eu/ ) in combination with USDB ( https://usdb.animux.de/ )?

There’s also a program for automatically downloading the songs: https://github.com/bohning/usdb_syncer

abustamam3• 4 months ago

Someone also shared https://github.com/rakuri255/UltraSinger

Which seems to output something that works with Ultrastar.

My sister loves karaoke as well and we grew up playing karaoke revolution and rock band. Shame they don't really make those anymore.

mynameajeff2• 4 months ago

Many thanks for sharing, I'll have to check it out this weekend. Do you have much hands on with it? Curious how much fiddling is required when using it. Haven't had a chance to run OP's either but my dream is to find something that's as intuitive to use as the older games. Even modern karaoke software you'll get at karaoke bar usually requires me or my wife to operate it for the entire rest of the group with how complicated everything is haha.

Looks amazing. I've been using Karafun [1], a paid service, but this seems promising.

kikokikokiko• 4 months ago

Karafun is a paid service? I've seen their karaoke songs on Youtube for over a decade, I thought that was their business model.

reddalo3• 4 months ago

Yes, the free songs on YouTube aren't customizable: there's a low voice guide that you can't turn off (or turn up...), and you can't change tempo.

You can do this from their huge catalog of songs, using their official app or their web client: https://www.karafun.com/web/

Plus, they have music quizzes you can play with many people using smartphones as remote controls. It's super fun for parties where people don't want to sing all the time.

mock-possum• 4 months ago

Unfortunately karafun, like so many other systems, has egregious holes in its catalog. I hate playing the “this song? No… this song? No… this song? No…” game.

reddalo3• 4 months ago

Psst... if you sign up to their Premium tier you can play songs from their "Community" (i.e. user uploaded songs). If you sign up to the "Pro" tier, you can play even more songs that are normally locked from their catalogue (but you'll have to manage rightsholders authorization yourself).

upsuper• 4 months ago

Really nice project, I'm looking forward to trying it!

Would it be possible to process songs on one device, and then use the result in another, or even multiple? Or would it be possible to run as separate server / client?

I ask mainly because the device I connect to my TV is definitely not the most powerful one, so it would be nice if I can preprocess the songs elsewhere.

rzzzzru27• 4 months ago

hi! answered here https://github.com/rzru/nightingale/issues/7

abustamam3• 4 months ago

My sister is non-technical but loves Karaoke. I'd love to use this or similar software to build a small box attached to her TV where she can look up any song on YouTube and generate a karaoke version.

I don't expect this feature to be magically built though, so I'll have to research how everything works, and maybe I'll contribue :)

rzzzzru27• 4 months ago

it's a false positive, however feel free to build from the source while I'm figuring out what the virus trigger is about

Eckter2• 4 months ago

Very nice!

I've worked on a small toy project with a similar purpose in the past [1], though it's not nearly as polished as yours, and I've made some questionable decisions here and there.

I have questions about pitch tracking. It seems you do track the pitch for scoring, and there's a line at the top of the screen that seems related but that I can't figure out. For my use case, an important feature of karaoke apps is displaying how "high" the next note should be sung, or at least some hints. Is it something your app can do and I just haven't figured it out? Or would it be a feature request?

[1] https://github.com/eckter/karaoke_helper

rzzzzru27• 4 months ago

hi there! pitch scoring is now pretty simplistic and the feature you're describing is not implemented. it's a great feature request tho!

skatedbear• 4 months ago

So cool! I'll try it with the steam deck. Being able to go to a party with just the deck and a microphone and have a karaoke with any song people want sounds good.

rzzzzru27• 4 months ago

I'm not sure whether the analysis would work swiftly enough on steam deck, it might be better to analyze on a desktop device and transfer ~/.nightingale/songs to the steam deck. just saying!

Gormo8• 4 months ago

Just downloaded source and built this to play around with it. I was a bit surprised that the first thing it did when I ran it was to start downloading binaries from the internet. It went off to fetch FFMpeg from some remote server, but I already have FFMpeg installed. Then it tried and failed to install its own Python interpreter, which is another thing that's already present on the system.

How come this is trying to install its own vendored dependencies, including executable binaries, instead of checking for what's already installed? That approach can lead to both security and performance issues.

Edit: the Python download isn't failing, but rather the application itself is looking for the executable interpreter in `lib` rather than `bin` once the download completes. I built the release tarball in the git repo, and I'm pretty amazed that such a basic error could make it into release code.

Further edit: I tried using the build script in the tarball rather than just doing a `cargo build -r`, and it started trying to install Docker containers! Docker to build a desktop application! What is going on here?

ramesh31• 4 months ago

Because the person who vibecoded this had no idea they should have been doing that.

user342833• 4 months ago

Personal attacks directed at people who build OSS are not cool, even if you take issue with their supposed use of AI or vendoring of dependencies.

solvik• 4 months ago

It’s a desktop app for mostly non-technical users, so bundling the runtime is a deliberate tradeoff to reduce setup friction and machine-specific breakage.

That said, an optional “use system environment if available” mode could make sense for advanced users. A PR for that would be welcome, as long as it also handles the real complexity involved: platform differences, Python package compatibility, GPU backends, and missing system/compiler flags.

rzzzzru27• 4 months ago

hey both!

thanks for your feedback and reports, I'd be happy if they are added as issues on github.

as said in the separate comment, I really wanted an app to be as "grandma-proof" as possible, therefore I really wanted to have one binary that does the magic for you. it's a karaoke app, not a tool that is aimed at engineers.

we can indeed look at the local packages before downloading an executable, it's just not done yet but might be added in the future.

I've built this project out of passion and it's 100% open-source and free, so please keep this in mind when criticizing.

rzzzzru27• 4 months ago

I'm just using cross https://github.com/cross-rs/cross to build cross-arch. you can still use `cargo build`, it will just work.

Gormo8• 4 months ago

It did, but then the application didn't work because it couldn't find the Python interpreter that it itself downloaded into its own config directory.

raincole2• 4 months ago

instead of checking for what's already installed

Plenty of software come with their own Python runtime. Even Blender uses its own Python runtime. I can name so many apps with embedded Python runtime: Blender, Houdini, Bitwig, Substance Painter, Krita, etc. Checking for what's already installed isn't the norm. In Krita's case, it uses installed Python to build it... and in the building process it builds another Python runtime for its own!

This app should have probably bundled the runtime instead of downloading a new one though.

install its own vendored dependencies
lead to both security and performance issues

npm install and pip -r theoretically have the same kind of security issue. How many projects on github run this kind of command during build process? My guess is in the order of millions.

throw_await• 4 months ago

All reasonable Linux distro will patch these stupid things to usw the system interpreter.

bityard• 4 months ago

This is unfortunately becoming more common.

Just yesterday, I went to try out some cool new AI thing that was here on the front page of HN. It's written in Python. Great, I thought, that means I can put it into a virtualenv and just rm the whole tree when I'm done and my system will be exactly in the same state it was previously.

But sadly... no... the first time I ran it, this Python program started downloading and installing Node/NPM, and all kinds of other stuff to my machine WITHOUT even asking for permission. Sorry app developers, but my machine and my home directory are my workplace. They are curated property, you are NOT allowed to just install whatever you wish.

I expect this kind of behavior from programs whose only supported installation method is a curlpipe. (And I do avoid those.) I do not expect it from programs that claim to be installable by pip, or ship their own binaries. These NEED to be called out as vulnerable to supply-chain attacks at worst and extremely disrepectful to users at best.

ravenstine• 4 months ago

How come this is trying to install its own vendored dependencies, including executable binaries, instead of checking for what's already installed? That approach can lead to both security and performance issues.

I've been sympathetic to your viewpoint, and I can see why this kind of thing is becoming more common.

The idea that users can reliably supply their own vendor libs/execs for applications is a bit of a fantasy. Devs working on fixing issues caused by the user having a strange issue due to the version of Python or whatever that they have installed is largely a waste of time when the application can "simply" ship with the exact dependencies it expects. This is especially true when it comes to open source work. Dealing with weird edge cases because the user has a version of FFMPEG installed that, for whatever reason, is missing h264, is work that nobody asked for. Given that the audience of this kind of app is a general one (not specific at all to devs) then it doesn't make sense to require other system packages to be present; if things like Python and FFMPEG are not required and will be downloaded anyway as part of the app install process, then there's no point in not always doing that. If you think about it, it's hardly different from any other sort of software dependency. The dependencies are just relatively bigger.

Personally, I have no desire for my applications to use other executables on my system unless I request that they do so explicitly. I'm sympathetic to the idea from a mere efficiency perspective, especially when it comes to developer tooling. But a karaoke app? No offense, but why care? A Python interpreter will be anywhere between 50 and 200 megabytes. FFMPEG is even smaller, especially if you don't enable every single feature and codec. Compared to how ridiculously bloated your average basic mobile app is (without anything like a built in JIT), bundling a desktop application with something like Python provides a lot of power relative to the number of bytes added.

Gormo8• 4 months ago

The idea that users can reliably supply their own vendor libs/execs for applications is a bit of a fantasy.

That's why package managers and OS repos exist. Users shouldn't have to even be aware of this sort of stuff. In this case, though, when the application starts trying to download and install its own dependencies at runtime, instead of everything already being sorted out at build time, the user is made aware of dependency resolution, and now has to deal with the issues involved.

This is especially true when it comes to open source work. Dealing with weird edge cases because the user has a version of FFMPEG installed that, for whatever reason, is missing h264, is work that nobody asked for.

And that's what config tests at build time solve for, and have solved for decades.

HWR_14• 4 months ago

How come this is trying to install its own vendored dependencies

"Why does this new software do X?" is probably answered by "the vibe worked on my system"

selcuka3• 4 months ago

Not trying to sound like a luddite (I don't "vibe code" but I use LLM assistance), but after learning that Claude Code is a React app, I'm not surprised by anything anymore.

mft_3• 4 months ago

It's probably pertinent to mention that the Python installation ecosystem is a hot mess, with multiple ways of installing Python (e.g. standard Python installer, multiple different packages managers on different OSes, Conda, and myriad package managers which can also install Python. And of course, these can all be in different locations, and may have different approaches to installing libraries.

Which is to say, I don't blame the author for wanting a single installation that his app can manage and rely on, even though I wish it was different.

cynicalkane• 4 months ago

The app is vibecoded. The author isn't making decisions about these tradeoffs and possibly wasn't aware of the implications of these decisions at all. The robot they used tried to fulfill its given prompts at the expense of everything else, which is why it's looking in bad directories and trying to install Docker environments in the build script.

I suspect that some of the author's comments in this thread are vibe-written, also. They are LLM-flavored and contrast strongly vs. their regular commenting.

Static linking packs the dependencies into the executable. This is basically dynamic vendoring.

mft_3• 4 months ago

Big karaoke fan, so thanks for doing this. I'm processing a first test song as I write. The pitch scoring sounds really interesting as both a competitive and maybe also a training tool.

A couple of immediate small pieces of feedback:

* The colour scheme on the queue/nn% buttons is really low contrast - white on pale yellow is very hard to read

* the 'models' button (bottom left) - I assumed this would give me details about which models are available, and the sizes, but instead deleted the downloaded models without warning. Maybe add a 'are you sure you want to...' check?

so, as answered in one of the other threads - for me the transcript model performed poorly back in the days, however since then I've added lyrics lookup and tweaked a bunch of parameters, so it is worth trying!

danvoell• 4 months ago

Nice work! If you are looking for ways to enhance this or complementary routes, one thing I was thinking about recently... As a musician, often I play songs I don't know the lyrics to. It would be cool to have an app that could follow along karaoke style with the words, as I sing and as the band plays. Right now I clip a phone to the mic stand, but after a lyric or two, I lose my place. This is probably multitudes more complex based on every "band/vocals" sounding different, but just something I was thinking about.

ted537• 4 months ago

Yeah I think this is quite tricky. Even spotify screws up the sync halfway through the song somewhat frequently

EGreg• 4 months ago

This is great! I thought of doing something like this for Karaoke, but was wondering about the copyright implications of doing it server-side.

We already do this for ingesting podcasts and cutting their clips with text being highlighted as people speak. AssemblyAI also supports speaker diarization.

For videos recorded using our own livestreaming studio, we can bypass all this by using Web STT and TTS APIs resulting in perfect timing and diarization without the need for server side models.

charcircuit4• 4 months ago

It's problematic even client side since you don't have a sync license to show words timed to the song. A bunch of other licenses are needed too for the lyrics themselves and to process the original file into the instrumental.

This gave me a blast to the past to Nightingale, the media player built on top of Firefox. It was a Firefox fork that was aiming to be a more powerful alternative to iTunes/Winamp. But since it was built on Firefox, you could also use it as an all-in-one media player and web browser.

The homepage still exists, but it looks like many of the other pages like the blog and wiki are long gone. It hasn't been active in probably over a decade.

rgilliotte• 4 months ago

Looking at the commit history, this came together pretty fast. Assuming it's AI-assisted (hard to know for sure), it's a good example of the opposite of the "AI replaces developers" narrative.

AI is making whole categories of projects viable that simply weren't before. Not because they were technically impossible, but because they were too time-consuming for a niche audience to justify the effort.

Thanks for the cool project! (testing now)

LtWorf6• 4 months ago

Similar software existed at the time of windows 95. A pentium 2 could do it.

Karaoke software? Sure. Karaoke software that automatically extracts vocals? Heck no.

abustamam3• 4 months ago

I've built so many fun projects that I've been meaning to build using AI, and my boss has as well.

I do agree that AI does make a whole category of projects feasible, but I disagree that AI does not also replace developers.

Should AI replace developers? I'd argue no, and the recent Amazon outage proves that.

But is AI replacing developers? Many companies seem to be doing so, whether or not it's a good idea.

I've also subscribed to the idea that even if AI doesn't replace me, I could be replaced by a developer using AI, so it's in my best interest to understand how to use it effectively (hence the projects!)

rjh292• 4 months ago

I introduced it to my friend (who is not technical, and has a RTX 3080), his experience was: he selected a 3:32 song, it took 10-15 minutes trying to scan it. In the end it did a "decent job of removing lyrics from the audio and providing accurate ones" "It seemed to be tracking my singing but there is no mic setup or anything like it" "And I think I accidentally wiped the AI model data it took forever to generate with a single click"

In the end he's gone back to karaoke videos on youtube but it seems promising.

This is cool, though for me personally my minimum quality bar for the lyrics and sync accuracy in karaoke is much higher than what's achievable with WhisperX / Force Alignment. I moved on from that approach about 2 years ago in my pursuit of high quality karaoke.
