You mean the Spexx codec? Thanks for the hint, I will have a close look at it..

I need wavs because:

1. As I understand the pygame-mp3-playback capability, I can't have more 
than one active sound at the same time. (Is that right?) We need to overlay 
the word sounds with special sound effects indicating long vowels, special 
syllabic and prosodic properties of the words etc.

2. The program uses about 200 different words and we currently have 
recordings from 6 different speakers.  We want to have recordings from many 
different dialect regions and users (mostly teachers/therapists with low 
technical skills and low tolerance concerning any "extra effort") should be 
able to create / modify and provide their own sound file packs. In my 
opinion, zip-files containing wavs are the most "common-sense" format.

3. We plan to incorporate some phonetic analysis algorithms to detect vowel 
length, syllable cut prosody etc. which can be directly applied to wav files.

All three points are not too strong contra non-wav formats, so if anyone 
has a good idea for my problem, it'll be highly appreciated.

Happy pygaming,
Tobias
