Sony's headphones do digital signal processing of the incoming signal. For instance, there's a user adjustable equalizer. This happens in the headphones themselves, rather than on the device they're connected to. This stuff does truly benefit from a higher bitrate.
- rasz 5y agoHow do you benefit from the recorded signal in bands humans are unable to hear?
- smoldesu 5y agoThat's not how audio codecs encode audio though. If we directly cut off bands that were difficult to encode, most codecs would stop writing anything above 1500hz, and then you'd be listening to a useless mumbled mess. A lossy audio codec will use the FFT algorithm to encode the entire spectrum, and the quality controls how aggressive the algorithm quantizes the waveform (through a process called sampling). On a lossless file, the compression will decode to an identical representation of the original master.

- goalieca 5y agoHehe. You jest but MHz is the range of ultrasound and is pretty useless in air.
