...le my audio before starting encoding, Opusdec looks into the Opus file and reads: "Aha, the original sample rate was 48 kHz, not 16." So even though the effective sample rate of the encoded data might be something like 16 kHz, Opusdec actually resamples it to 48 kHz. > Ah, so you _hear_ when the frequency reaches 8k exactly? Yes. When I turn the playback rate down to 12 kHz, the original 8 kHz is changed to 2 kHz, which makes the pitch clearly recognizable. And now that I've discovered what happens if I set either something like "--expect-loss 60" or "--bitra...

When I first tried encoding at a higher bitrate, I needed to test the different behavior of the "mid" (l+r) and "side" (l-r) channels. That's why I made the first sweep identical on both the left and the right channel (i.e. "side" is silent)

Here is a letter I sent them for my $150 paper weight. Dear Voipsupply, As a small service provider, using you company for the first time, I'm very disappointed that you have removed the configuration CD that should have been shipped with the Mediatrix 2102 just to get a few more bucks. I have contacted mediatrix and they have informed me that the CD's is shipped in every 2102. If I
