a clear cut-off at around 12KHz with opus encoding setting (32KHz sampling rate, @16kbps)
Hi,
I am trying to encode speech samples with OPUS at 16kbps, a 32KHz sampling rate. It is observed from the decoded audio that there is clear cut-off at around 12KHz (expected to be 16KHz). I am not sure whether or not it is a bug or it is simply the limitation due to the low bit-rate setting? Any one can help me on this? Thanks very much in advance.
Thanks Tim
