Hello,

does anybody know if any of the MC7xxx devices supports AMR-WB?

Thanks for your support!

According to information I have the MC7304 should support HD voice(AMR-WB).

Thank you for your answer,

i should ask a litte bit more detailed. We need to use AMR-WB with the full samplingrate which is 16kHz in AMR-WB.
Many modules do support AMR-WB but we experienced a downsampling to 8kHz. Does anybody know whether the samplingrate has 16kHz or if its possible to change the samplingrate via AT-Command?

Thank you,
Pascal Behr

Any further info on this? I’m unable to find any reference on AMR-WB support in MC modules. Do any modules support it, and at 16KHz?
