Thanks. That solved my problem.

Also,
I installed lame codec but I am not sure how to tell ffmpeg about a new codec?
Does ffmpeg need to be precompiled or can I modify some config file or
tell ffmpeg to use my codec?

ffmpeg -i voice.wav -ar 22050 voice.mp3
tried
ffmpeg -i voice.wav -ar 22050 -acodec mp3 voice.mp3
but still writes mp2

Unless there is a different command? Please list any that might appropriate.
Thanks,
Lucas
