Play audio file (AAC) from ruby program

ruby-talk

I need to play, pause and resume AAC files from a ruby console program
(much like iTunes or any music player).

After much searching, I've come across these libraries:

1. mp3info
2. metadata
3. id3lib-ruby
4. rvideo (uses ffmpeg)

These seem to help me in getting track length and tags which i also
need, but I need something to play AAC (at least) and if possible other
formats. I also must be able to pause and resume (so shelling a program
like mpg321 is out).

if its for the mac, you could use MacRuby with QTKit.

I'm not saying it's the best solution, but you can use mpg321 to
pause and resume. I think you need to use -R

I am on a mac, but this is a console program so should be usable on
other systems too. Also, Macruby makes it a GUI program, I am using a
character terminal.

Thanks, I just tried it. It gave a malloc error complaining first that
it could only do 44Khz files. (Crashed out on LOAD).

You might also try mplayer in -slave mode. I know that can handle 48k audio.

I've come across a Snack Sound Toolkit,
http://en.wikipedia.org/wiki/Snack_Sound_Toolkit -- seems to be some
ancient bindings to it, less than alpha and untested. It also requires
Tk.

portaudio has some ruby bindings to it: paruby and ruby-portaudio
(http://github.com/jvoorhis/ruby-portaudio/blob/master/lib/portaudio.rb#).
The latter is Feb 2010 the other (paruby) seems quite old and perhaps
abandoned (updated 2006, status: in development).

Someone suggested "afplay" -- this is a command line utility on OSX.
Unfortunately, does not allow me to pause resume.

So it looks like ruby-portaudio may be the best bet at present.
