Only problem is that WavPack is not widely spread out (it is part of the FFmpeg and as such easy available on many platforms but that isn't really enough). Combining lossy and correction files you get original bit perfect Wav back. In comparison to rav DSD bit stream that would be 4~5x compression. Where you can get 50~33% (depending on source complexity) smaller output file for HiFi 88200~96000 Hz 24 bit (or above) than Flac while not being able to hear the difrence and having rest stored in correction file. WavPack is very interesting in lossy hybrid mode with corestion (restore) graph. You can and should cut obove 35 KHz on DSD output. Flac is WAV with data compression, WavPack daos compression part better (better than both Flac and Apple losseles) but it's not widely present. Keeping the same in Flac saves you more than half storage space (2x compression). Meaning you don't really need to keep it as DSD bit stream on your storage device. I stated already that conversion is (exact) bit perfect. TL DR: 24/88 is probably fine.ĮSS has a complex DSD design including physical separate and better authended line. Here's a thread on comparable DSD and PCM formats. ultrasonic noise is at best irrelevant and at worst detrimental to following stages, and it's not helping lossless compression one bit. You may actually want to not go overboard with target sample rate for this particular reason. ![]() Synchronous resampling at high quality is not a major challenge these days, and target sample rates tend to be so high as to be covering frequencies far beyond the audible range, so everything removed would only be shaped noise anyway. ![]() If the playback setup involves a ground loop in unbalanced cabling, all bets are off. Transcoding might be discarding / ignoring ReplayGain information, which would result in a level difference. Rockbox on ARM decodes it around 3 times as fast as MP3, at around 8 MHz for realtime. FLAC was literally designed to be as lightweight as possible on the decoding side, with speeds of 425x-450x on a 2.8 GHz Core 2 Duo T9600.
