[maemo-developers] Efficient storage and playback of speech

[From: Gibro Vacco]

Hi,

in my opinion ogg/vorbis should be good enough, but it requires to install the extra codecs. If you prefer a proprietary solution mp3 is also quite good, and you can encode on your favourite linux distro withe lame.

I don't suggest to try esotheric experiments like g729 encapsulated in a container format.
