Ask HN: Noise in Hi-Fi has reached unbearable thresholds. How to lower static?
- JPLeRouzic 4y agoFor amplifiers: switching amplifier with Pulse Width Modulation and for cables: digital modulation (from QAM to OFDM) with LDPC for error correction ?
- JPLeRouzic 4y agoI guess a switching amplifier with digitalized PWM could have LDPC in feedback loop? If you pay me a lot, I can write a patent for you!
- PaulHoule 4y agoWhat do you mean? I remember cassette tapes having terrible hiss in the day. I have been listening to a lot of music on Minidisc lately and overall like it but after somebody pointed some thing out to me I think ‘are they using white noise as a coding tool?’ (AAC Pro does) but I really have to listen to the CD next to the MD to be sure.
