Issue with decoding 8-bit PCM data
...and hence except for some loss of quality on 8 bit, they are identical in total play back duration. For both 8 and 16 bit data I have used the following parameters ui32SamplingRate = 8000 ui32Channel = 1 FRAME_SIZE_IN_MS is 20 MAX_PACKET is 1500 ui8ScaleFactor = 1 for 8-bit and 2 for 16-bit data ui32BitsPerSample = 8 for 8-bit data and 16 for 16-bit data The code is as follows sOpusDec = opus_decoder_create(ui32SamplingRate, ui32Channel, &i32error); if (i32error != OPUS_OK) { return((int)i32error); } opus_decoder_ctl(sOpusDec, OPUS_SET_LSB_DEPTH(ui32BitsPerSample)); ui32SizeOfWrBuf = (ui32Sam...

Issue with decoding 8-bit PCM data
...the extending the 8-bit to 16-bit? 2. If that is the case then how will 24 bit PCM sample work?
