AIFF vs W64
Ein detaillierter Vergleich von AIFF Audio und Sony Wave64 — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
AIFF Audio
Audio FilesAIFF is Apple's uncompressed audio format, equivalent to WAV in the macOS ecosystem. It stores CD-quality PCM audio and is widely used in professional audio production on Apple hardware.
Über AIFF-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
AIFF Vorteile
- Lossless and uncompressed — bit-exact audio reproduction.
- Native to macOS and all Apple Pro Audio apps.
- Simple structure — trivially parsed by audio libraries.
- Supports up to 32-bit float, 192 kHz, and multi-channel audio.
- Rich metadata via named chunks (annotations, markers, MIDI).
W64 Vorteile
- Unlimited file size (64-bit chunks).
- Professional DAW compatibility.
- Bit-exact lossless.
Einschränkungen
AIFF Einschränkungen
- Enormous file sizes — 10 MB per minute at CD quality.
- No built-in compression — use FLAC for lossless with smaller files.
- Big-endian byte order confuses tools written on little-endian hardware.
- Less common on Windows; WAV is the local equivalent.
W64 Einschränkungen
- Less universal than WAV.
- Niche — only matters for very large sessions.
- Competes with RF64.

Häufig gestellte Fragen
AIFF (AIFF Audio) 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 AIFF 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 AIFF 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.
AIFF 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.
