Audio file conversion for Josh (m4a to mp3)

gistfile1.txt

First, we need FFMpeg's binary (put binary where it can be found in the load path):
http://ffmpegmac.net/

Next, in order to encode a file as mp3, we need Lame (currently tested with 3.99.5):
http://sourceforge.net/projects/lame/files/lame/3.99/

Untar the library:
$ tar -zxvf { file_name }

Run Lame's configure script (using the default configuration for this is fine):
$ ./configure

Then run make
$ make

Then install
$ make install

Now Lame and FFMeg binaries are installed, let's convert an m4a file to an mp3 file:

ffmpeg -i {file.m4a} -acodec libmp3lame -ab 160k {file.mp3}

And that's it. ^_____________________^
