I am trying to determine if the OpenMoko GSM voice can be modified by software.
I have heard "it is possible" and "it is impossible". One of these is true.
Does anyone know any details about how it is possible?
The CODEC details are here:
Looking at the OpenMoko audio path, it seems that there is no way to
modify GSM voice.
* audio path Mic -> GSM
o Mic2 Volume
o ALC Micer Mic2
o Left PGA
o Mic Sidetone Mux [Left PGA]
o Mono Sidetone Volume
o Mono Mixer Sidetone Playback Switch
o Mono Volume
o Mono 2 Mux [Inverted Mono 1]
* audio path GSM -> Speaker
o Rx Mixer [RXP - RXN]
o Line Left Mux [Rx Mix]/Line Right Mux [Rx Mix]
o Left Mixer Bypass Playback Switch/Right Mixer Bypass Playback Switch
