Comment on Audio dongles and the ghost of USB 1
fleck@lemmy.world 3 days agoThe observation is that most USB-C to 3.5mm (“aux jack”) audio dongles are supporting high quality audio but only support the USB Full Speed (FS) data rate which is not enough for the high quality audio. This causes problems.

“High Quality Audio” in terms of the sample rate and bit depth, but considering the quality of most of these DAC/ADCs you get integrated in cables like this, I somehow doubt the data rate is actually the limiting factor on quality.
Personally I can’t tell the difference between 192kHz and 92kHz samples rates, or 16bit and 24 bit either (maybe a young kid with perfect ears could, but they’ll probably also notice background noise due to most of these using unfiltered USB power). The dongle manufacturers seem to care more about the marketing value of bigger numbers than actual usability.

Plus, your source files would also have to actually be in that format. As an example, Spotify apparently supports up to 24-bit/44.1 kHz FLAC only

Ironically, the conclusion is that the stupidly high claimed sample rates are a good indicator that these dongles won’t be afflicted by this bandwidth-scheduling problem. Though they can have various other issues.
