ste7an ste7an at gmail.comI am trying to convert the voice.raw file generated by the mobile application ion the Sylvain's test branch to audible audio using the GAPK tool. I seem not to be able to run in with the apropriate parameters as I only get screeching sounds as a result. I assume the the raw TI calypso audio is in the format indicated with ti-fr. I tried things as: gapk -i voice.raw -i voice.pcm -f ti-fr -g rawpcm-s16le but with no usefull result. Could anyone give me some guidance? regards, Stefan ----------------------- this is the output of the GAPK tool as I compiled it with the supported codecs. Is there anything missing?
