Audio processing libraries for Ruby?

Question

Any recommendation on libraries to do audio processing in Ruby. I need to do the following two tasks:

Find silences, for which I'm happy to just be able to iterate over each sample in the wave.
Cut and paste pieces of wav files to form a new wav file.
Convert wav to mp3, which I will probably leave to lame anyway.

I'm looking for the equivalent of NAudio, a C# library.

If Ironruby is an option, why not use that and link directly into NAudio since you're familiar with it? — Dan Fitch, May 19 '10 at 19:30

One option is ruby-audio, which has a wrapper over libsndfile.

Personally, I haven't had much luck with audio manipulation in pure ruby, but I have used Java libraries from jruby to good effect.

Ruby-Processing and minim - although this adds a different layer in from Processing, it's pretty cool.

Good luck!

Don't use fugal's ruby-audio. It's slow and buggy. The latest version is done by warhammerkid (myself) and can be found at http://github.com/warhammerkid/ruby-audio. I generated the rdocs and put them up on my server at http://doc.chromedshark.com/ruby-audio/ so glance through them and see if it works for you. – warhammerkid May 20 '10 at 22:42
You could use rdoc.info to automatically generate the docs. – Pablo Fernandez May 24 '10 at 10:12
It would be nice to know which Java libs you've used, for reference. – Jose Alban Oct 16 '15 at 14:28
