SND vs W64
Ein detaillierter Vergleich von NeXT Sound und Sony Wave64 — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
NeXT Sound
Audio FilesSND (NeXT Sound) is an audio file format originating from NeXT computers and later adopted by Sun Microsystems as the AU format. It stores audio with a simple header and supports various encodings from 8-bit mu-law to 32-bit floating point.
Über SND-DateienSony Wave64
Audio FilesWave64 (W64) is an extension of the WAV format developed by Sony that breaks the 4 GB file size limit of standard WAV by using 64-bit chunk sizes. It is used in professional audio production for very long or multi-channel recordings.
Über W64-DateienVorteilsvergleich
SND Vorteile
- Historical NeXT archive format.
- Compatible with Sun AU.
- Simple header structure.
W64 Vorteile
- Unlimited file size (64-bit chunks).
- Professional DAW compatibility.
- Bit-exact lossless.
Einschränkungen
SND Einschränkungen
- Legacy — no new content.
- Ambiguous — NeXT .snd and Mac .snd are different formats.
- Requires specialized tooling for Mac resource-fork variant.
W64 Einschränkungen
- Less universal than WAV.
- Niche — only matters for very large sessions.
- Competes with RF64.

Häufig gestellte Fragen
SND (NeXT Sound) 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 SND 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 SND 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.
SND 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.
