Rawdio 0.1.0

November 21, 2007 at 2:33 pm · Filed under Rawdio, Ruby

I’ve wrapped up my WAV file wrapper and stuffed it into a gem. As it stands it can only take audio data as a byte string and write a WAV file for it, but sine/square/triangle wave helpers (and more!) are on their way. I’m also hoping to add support for other “raw” audio formats soon.

require 'rubygems'
require 'rawdio'

white_noise = Rawdio::WAV.new
8000.times { white_noise << rand(255).chr }
white_noise.write('sweet_sound.wav')

Have at it (if you have the need):

sudo gem install rawdio

    Not sure what I’ll use this for but I love the idea. I shall have a tinker.

    I’ll be really interested in using this once you’ve got a few helper functions!

    I’d like to play, but the gem is 404ing when you try to install…

    @monki,

    Hmm. Maybe you caught Rubyforge at a bad time. I see the files and grab the gem just fine now.

    @Chris,

    Yeah, sorry about that. It started being wonky with other gems too for some reason. I’m guessing something in my install. After a “gem update –system” everything seems on track again, thanks.
