Probably marketing and the HiFi industry has demonstrated that such people are a nice niche income stream. Some say a fool and their money, I say each to their own and their choice.
But I'm sure there are always edge-case valid uses for such audio quality. Maybe talk to bats and dolphins in the future is now one step closer than before is another way of looking at this.
- astrange 6y agoOpus doesn't support any sample rates higher than 48khz, so no bat encoding. Some other audio codecs do, but it doesn't really make a lot of sense and I doubt they've been properly tuned for it.

- jancsika 6y agoBut that 500kbs sound just feels warmer to me (on my laptop).
- pfalafel 6y agoI think the 500 limit is a max bitrate setting, independent of any specific codec. If you deliver audio+video you will need to consider exactly how much of the bandwidth you use for audio. But when doing audio only, simply using the highest possible bitrate seems to be a reasonable choice. In most cases the network will set limited.
- astrange 6y agoSamplerate is an independent dimension of bitrate - although not really because lower bitrates can store fewer samples. It's equivalent to the resolution of an image.
- meepmorp 6y agoSample rate is limit on the frequencies in the original signal that you can represent in your digitization without aliasing.
- phkahler 6y agoSample rate != bit rate. 48khz samples at 16bits each is 768kbps mono. 1.5Mbps stereo. But that's before compression.

- astrange 6y agoThe point was that Opus can't store bat sounds because they're ultrasonic and it isn't. Dolphins may be possible though I think whales might be filtered out due to being subsonic.
- adamzochowski 6y agoOpus at sample rate of 48khz, still only encodes frequencies up to 20khz of listening range (think of opus as having 40khz sampling rate). This is same as audio CDs, which although are in 44khz sampling rate, have a red book recommendation to always filter out anything over 20khz. Thing is, most people can't hear well over 16khz. Some can hear 18khz. 20khz is peak possibility. To encode 20khz wave we need 40khz sampling rate. Everything else is marketing.
