Full Version: Best codec for Audio books (WMA or MP3)

Hiya. I have several Audio Books, and I'm looking to store them as small as possible.

My DAP will play either WMA or MP3 files, so it's a choice between either codec.

Can anyone suggest which codec will get them the smallest?

If those audiobooks are speech only try using lame with the following command-line:

'lame -V 4 --lowpass 10 -m s -a'


You can play a little with the -V switch and the lowpass to try and get to your quality/file size sweet spot.

Why would you need -m s and -a? I'd say -a would be enough; that or -m m.

Indeed; in fact, you could probably go down to -v6 or even -v7 and have the ebooks still listenable-to, if you try lowpassing at.. say.. 8000?

-a 

mix the stereo input file to mono and encode as mono. 

This option is only needed in the case of raw PCM stereo input
(because LAME cannot determine the number of channels in the input file).
To encode a stereo PCM input file as mono, use "lame -m s -a"

For WAV and AIFF input files, using "-m m" will always produce a
mono .mp3 file from both mono and stereo input.


I got this straight from the lame usage manual...
