![]() I played DSD files through the standard analog stereo audio output jack found on the motherboard. No special audio hardware was used even though DSD integrated circuits on studio-grade recording hardware do exist. The point is that these are two different techniques, and to play DSD on Linux, some form of conversion into PCM is required - at least given the common consumer-grade computer hardware that I had available. The differences over “which is better” can lead into some advanced acoustics theory and mathematics (in addition to heated audiophile debates), so we will leave those topics alone. If you convert DSD to PCM, can it still be called DSD? DSD is a 1-bit pulse-density modulation technique while Linux (as well as other operating systems, so this is not a Linux issue) is glued to the PCM (pulse-code modulation) technique utilizing 8/16/24/32 bits to represent audio. Yes, but this is where the controversy lies. dff (DSD Interchange File Format/DSDIFF) audio files. ![]() Some online music stores offer high-resolution music as a DSD download in order to offer the best sound quality possible that are as close to the original recordings as possible. ![]() Introduced in 1999, the SACD technology never caught on, but the underlying encoding mechanism, DSD, is still around today. Remember those? They were often hybrid CDs that contained standard CD audio for playback on regular CD players in addition to high resolution audio that offered improved fidelity and more audio channels to accommodate surround sound. DSD, the acronym for Direct Stream Digital, is the audio encoding format
