SHN vs W64
A detailed comparison of Shorten Audio and Sony Wave64 — file size, quality, compatibility, and which format to choose for your workflow.
Shorten Audio
Audio FilesShorten (SHN) is one of the earliest lossless audio compression formats, developed by Tony Robinson. It was widely used in the live music trading community for sharing concert recordings before FLAC became the dominant lossless format.
About SHN filesSony 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.
About W64 filesStrengths Comparison

Frequently Asked Questions
SHN (Shorten 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.
W64 (Sony Wave64) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects.

It is part of the audio files family.
VLC, foobar2000, and the default media players on Windows and macOS handle SHN 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 SHN 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.
SHN 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.
