...ereo file containing the same sweep in both channels and then downmixing to mono? Also, why are you repeating the sweep twice in every channel? Also also, the file you linked to is Sweep50FlatMidSide.wav as opposed to Sweep50.wav - is it really the same file? > 2) Opusdec --float Sweep50.opus Sweep50out.wav Why are you using floats for the decoded file? > > The strange > > thing was that even though the output wave file was at 48 kHz, it showed > > clear marks of being resampled from 16 kHz The encoded opus file is 48kHz, so how would the output wav be resampled from 16kHz?

...Can you please make that sound file available? It is hard to tell without having anything. (50s of sines shouldn't be large.) > > and how exactly did you encode and decode it? > > 1) Opusenc --bitrate 12 --downmix-mono Sweep50.wav Sweep50.opus > 2) Opusdec --float Sweep50.opus Sweep50out.wav
