ffmpeg

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

-i - ignore errors

-c - continue

-t - use video title as file name

--extract-audio - extract audio track

run

$.each($('h4 a'), function(index, video){
  console.log(video.href);
});
