DSP in Go

I was about to ask if there was a good place to look at available packages for Go. The godoc.org[1] website referenced from this repo looks like a really great start with a searchable index and docs. The active community around Go has really impressed me.

Yes, godoc is one of the best resources for go programmers. The standard library and community packages all cross linked in one searchable, modern interface with direct links to the code.

There's also a new supplementing one called http://go-search.org/ which makes it easier to search packages by keyword, and sorted by some kinda score.

Take a look: http://code.google.com/p/go-wiki/wiki/Projects :)

I also stumbled on this site the other day:

Not in love with some of the formatting, but has proved useful from time to time.

I've never used Go before, but this is making me seriously consider trying it out. All of the DSP classes I've taken recommend Matlab + the DSP toolbox, and I would love to have a serious alternative.

It depends on what you mean by "a serious alternative". DSP functions exist in python too (http://docs.scipy.org/doc/scipy/reference/signal.html), but where MATLAB wins out is with their Simulink library, which doesn't have an open source alternative.....yet. AFAIK.

There is Scicos [1] which is the "Simulink" of Scilab, itself a Matlab-lookalike.

You've been taking the wrong classes :P No, seriously, there's way more to DSP than matlab. You can pretty much do it in any language. For example in shool we used C++ combined with the Intel IPP libraries (which are really fast btw). The first book I bought for a job was C + bits of optimized assembly since it was written specifically for a TI Dsp. I've also played with it in Python but don't remember the lib name atm.

I soooo agree with this.

"Twiddle factor? What the..."

You might scratch the surface of DSP by taking a Matlab-centric course, but if you'd like to do it as a career you're far better off to go in and implement some of the more fundamental algorithms you're using.

Implementing FFT or DCT on actual hardware (which supports a multiply/accumulate instruction over a true DSP memory architecture) will give you the tools that you need when it comes time to troubleshoot (read: use) some vendor's shitty proprietary DSP library.

That said, learn the Matlab stuff too. It's endlessly useful for prototyping, and it's pretty much industry standard in this use. Just don't take it for granted.

It's hard to say this would be a serious alternative from a first glance. Matlab has a rich history and an enormous breadth and depth of support just doesn't have.

This Go code hasn't broken into filter design, visualization or multi-rate methods. I still think its cool that OP is working on this but its far from being a true alternative to Matlab.

There's also a nice set of FFTW bindings. https://github.com/runningwild/go-fftw

For those wondering which of the many DSP acronyms this is referring to, it's Digital Signal Processing.

aylons2• 13 years ago

Actually, now I am wondering what are the others, at least the reasonable ones.

I can only think on Digital Signal Processing.
