The surround sound and HRTF on the PlayStation 5 exceeds my expectations. On the famous tech conference, they talked about calibrating the sound space relative your ears to get the best possible surround feel, but that's yet to come.
- fxtentacle 5y agoFrom what I heard, that's convolution via FFT, so in effect very long FIR filters. And yes, they should be able to fully customize things for your ears and for the headphones by pre-multiplying in the appropriate equalizer FIR filters into the 3D room impulse response.
- Bancakes 5y agoI have no idea what you just said, so I upvoted.
- junon 5y agoHow does this work, though? They'd have to parameterize it based on the actual room, right? Does that mean the user has to calibrate things manually?
- crtasm 5y agoPerhaps it can be done with the microphone in the controller?
- fxtentacle 5y agoYes, there are algorithms to estimate the room impulse response from speakers and a microphone.
- SSLy 5y agoSony has ear-specific IR/TF tech on android. You can get their app to take a photo of your ears, get the blob back. Tidal and Deezer in turn can use some 360 sound API to play their surround music through this.
