DSF vs TTA
Ein detaillierter Vergleich von DSD Stream File und True Audio Lossless — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
DSD Stream File
Audio FilesDSF (DSD Stream File) stores Direct Stream Digital audio data with metadata support. DSD uses single-bit sigma-delta modulation at very high sample rates (2.8 MHz and above), providing extremely high resolution audio favored by audiophiles.
Über DSF-DateienTrue Audio Lossless
Audio FilesTTA (True Audio) is an open-source lossless audio codec that provides real-time lossless compression with hardware-friendly decoding. It achieves compression ratios similar to FLAC while maintaining very low CPU requirements during playback.
Über TTA-DateienVorteilsvergleich
DSF Vorteile
- Preserves SACD audio bit-exact.
- Appeals to audiophiles who prefer DSD-encoded content.
- Sony-supported and documented.
- High-end DACs natively decode DSD without PCM conversion.
TTA Vorteile
- Lossless bit-exact reproduction.
- Fast, low-memory decoding.
- Open-source reference.
- Cue-sheet support.
Einschränkungen
DSF Einschränkungen
- Enormous file sizes (2-5 GB per album).
- Specialized hardware required for native playback.
- Blind listening tests struggle to distinguish from well-produced 24-bit PCM.
- Niche — overwhelmingly targets the audiophile market.
TTA Einschränkungen
- Compression ratio worse than FLAC.
- Niche tooling.
- Hardware support died with 2000s DAP era.
- Eclipsed by FLAC.

Häufig gestellte Fragen
DSF (DSD Stream File) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects. The format defines how the audio samples are compressed (or stored raw), what bitrates are supported, and how metadata such as title, artist, album, and cover art is embedded. It is part of the audio files family.

VLC, foobar2000, and the default media players on Windows and macOS handle DSF natively. On mobile, iOS Music and Android media apps vary in their support — popular formats work everywhere; niche ones may need a dedicated app. If playback fails on a device, converting to MP3 or AAC usually solves it.

Upload the DSF to KaijuConverter and pick MP3, WAV, FLAC, AAC, OGG, or any other target. Our FFmpeg pipeline decodes the audio and re-encodes to the target format at sensible default bitrates (VBR ~190 kbps for music, 96 kbps for speech). Metadata and cover art travel with the audio where both formats support them.
DSF can be lossy or lossless depending on the specific variant. Lossy variants (smaller files) discard some audio detail during compression in ways tuned to be inaudible; lossless variants preserve every sample exactly but produce larger files. For distribution, lossy at high bitrate is standard; for archival, lossless wins.
