Hello,
I am using the TGE module from VoLIB to generate DTMF tones into a stream of linear voice data with a sample rate of 8 kHz on a C6678. After adding the tones, I then encode the data to G711 uLaw and playback the result.
My code is basically a modified version of the demo code for TGE that comes with VoLIB. If I set 'sample_rate' in the tgeConfig_t struct to tge_SAMPLE_RATE_8K, the output sounds correct. If I set the same parameter to tge_SAMPLE_RATE_16K, the output sounds the exact same even though I would expect the tones to be 16 kHz in an 8 kHz voice stream and sound incorrect.
Are there other config parameters or settings that need to be changed as well for 16 kHz sampling rate or does this setting really have no effect?
Regards,
Chris
