Creating small short audio files with sox for android

I create around 1000 audio files via sox for my android application, each containing a recording of a word. To safe space I want to keep the file size as small as possible.

Should I use .mp3 or .ogg? Which settings should I use?

Since Android supports both of the codecs natively I would definetly choose the Vorbis codec. At low bitrates the Vorbis codec produces a much higher clarity than MP3 and even the file size is smaller.

In general I would recommend to encode the sound files with the aoTuV encoder (which is a third-party development of the official Vorbis encoder which further improves low bit-rate quality) in quality level 1 (approximately 80 kbps).

If little loss in quality doesn't affect your application than using audio-grabber to decrease the bit-rate of .ogg files will give you amazingly small audio files.

Have you checked that question on SO Smallest audio file: MP3, Ogg, or Wav? ?

@keyboardP said:

Of those three, Ogg would usually be smaller than MP3. Both would be much smaller than the uncompressed WAV. Of course, there may be other factors that come into play for your site such as quality (not too much of a noticeable difference for most purposes) and browser support for each type.

The file size will only affect the time it takes to download the file to the user's machine. It won't necessarily determine Javascript execution speed. There may be other things in your code causing the performance drops (unless you've narrowed it down to the file size of the audio files).
