Re: Compressing Voice Sound.

Of course not new chip. :)

No, no idea yet.... the one is my 12bit 1-V sigma-delta modulator ......
many problems there :p

Good, 4KHz.
Telephone quality is enough, when I speed up my Bluetooth transmission and
then I will select in advance.

Any suggestion codec? Just have a look/reference : )

I hope the data rate is as small as possible...


Best regards,
Boki.
