[mary-users] MP3 encoding on AMD64?

[Marc Schroeder]

Indeed, the built-in mp3 encoding depends on the availability of native 
libraries linked to lame -- we haven't tried to compile that code from 
tritonus on 64 bit architectures, but volunteers are welcome...!

Regarding the suboptimal sound quality, maybe the standard settings of 
the tritonus plugin for lame are not working perfectly with our 
(not-so-common) speech format: mono, 16000 or 22050 Hz... if I had the 
time, I would try to resample the speech signal in java into 44100 Hz, 
stereo, before passing it to tritonus, and then see if the quality gets 
better. Again, volunteers welcome...

Until then it remains an obvious alternative to do the compression 
separately, using external tools, as Stephen has pointed out.

Best,
Marc
