Playing around with my Klipsch Pro-Media speakers on the PC with the 'release demo page' (the OP linked to) I can notice differences on the speech samples (like while the audio file is playing I switch back and fourth between Opus versions at the following rates)... -9kbps = noticeable difference between v1.2 and v1.3 as it's a bit less muffled/more clear in v1.3. between v1.1 and v1.2 I don't notice any difference on this 9kbps setting. -12kbps = noticeable difference between v1.1 and v1.2 but nothing between v1.2 and v1.3 as far as I can tell. NOTE: I would say this one is harder to spot a difference between v1.1 and v1.2 vs the 9kbps and 16kbps settings I mentioned which are easier to spot. -16kbps = noticeable difference between v1.1 and v1.2 (basically less muffled and a bit more clear sounding) but I don't notice anything between v1.2 and v1.3. -20kbps = things start to get harder to notice between the versions but I think I can spot some difference between v1.1 and v1.2. -24kbps = I can 'maybe' notice a difference between v1.1 to v1.2. -32kbps/40kbps = I can notice some change in sound between v1.2 and v1.3. basically a bit more clarity I guess I could say. -48kbps = I can't say I notice anything here between Opus versions. NOTE: from what I have noticed so far in general with my limited testing with my speech files... I prefer no lower than 13kbps with Opus v1.3 and 14kbps with Opus v1.2.1 for general speech at the minimum. NOTE: I know headphones are optimal but I just thought I would list the above info for whatever it's worth
