INSTALLATION:
-------------

Simply compile by running 'make'

USAGE:
------

Then run the program, it will give you usage instructions.

It's really quite trivial to use.

For example, to decode input.m4a to output.wav:
./alac -f output.wav input.m4a

Or, as another example, say if you wanted to stream play
http://www.mplayerhq.hu/MPlayer/samples/A-codecs/lossless/luckynight.m4a
and you're system uses the ALSA sound system:
wget -O - http://www.mplayerhq.hu/MPlayer/samples/A-codecs/lossless/luckynight.m4a | ./alac - | aplay

By default the output file is in WAV format. To output as raw PCM, provide the
-r option on the command line.
