Frequently Asked Questions
What is DSD format?
DSD (Direct Stream Digital) is a high-resolution audio format using 1-bit delta-sigma modulation at extremely high sample rates (2.8-22.5 MHz). It was developed for Sony's Super Audio CD (SACD) and offers exceptional audio quality for audiophile recordings.
What's the difference between DSF and DFF files?
Both are DSD containers. DSF (DSD Stream File) was developed by Sony around 2005 and supports ID3 metadata tags. DFF (DSDIFF) was developed by Philips in 2000-2004 for professional interchange. Both contain the same high-quality DSD audio.
Why convert DSD to FLAC?
While DSD offers exceptional quality, FLAC provides much better device compatibility, smaller file sizes (40-50% reduction), and excellent metadata support. The conversion preserves most of the original quality while making files more practical for everyday use.
What sample rate should I choose?
48 kHz offers excellent quality and universal compatibility. 96 kHz preserves more of the original high-frequency content from DSD sources. 44.1 kHz provides CD-quality output with smaller files. For most listeners, 48 kHz is the sweet spot.
Will I lose quality converting from DSD?
Converting DSD to PCM (FLAC) is technically lossy since you're changing the fundamental encoding method. However, with proper filtering and high sample rates (48-96 kHz), the difference is imperceptible to most listeners, even audiophiles. The practical benefits often outweigh the theoretical quality loss.
