HOW TO CONVERT W64 → SHN
Provide the audio file
Drag the W64 onto the uploader. Files up to 25 MB run on the free tier without registration; paid plans go up to 2 GB.
ffmpeg handles the conversion
Our ffmpeg-based pipeline reads sample rate and channel layout, then writes a matching SHN with ID3 tags intact.
Save the output
Click to download the SHN. Batch uploads are bundled into a ZIP for single-click retrieval.
Why this pair exists — W64 is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. Ergo, the SHN route. A W64 to SHN transcode is mostly about compatibility, not fidelity. At sensible default bitrates you cannot tell the two apart by ear; what you get is a file that actually opens on the hardware or website you were aiming at. FFmpeg handles the heavy lifting and we stream the result straight back as a download. Context: W64 is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. SHN is an audio format with specific trade-offs between file size, bitrate flexibility, and device support.
Why convert W64 to SHN
Moving from W64 to SHN usually buys compatibility or a friendlier file size. For spoken-word content the difference is inaudible; for high-resolution music pick the highest bitrate the SHN codec supports to avoid compounding compression.

W64 vs SHN — Strengths and limitations
What each format does best, and where it falls short.
W64 Strengths
- Unlimited file size (64-bit chunks).
- Professional DAW compatibility.
- Bit-exact lossless.
Limitations
- Less universal than WAV.
- Niche — only matters for very large sessions.
- Competes with RF64.
SHN Strengths
- Lossless.
- Historical artifact of 1990s music trading.
- Modern decoder availability.
Limitations
- Historically royalty-encumbered.
- Obsolete for new recordings.
- FLAC offers better compression.
Quality & Compatibility
Sample rate, channel layout and bit depth are preserved by default: a 44.1 kHz stereo W64 becomes a 44.1 kHz stereo SHN. Metadata — title, artist, album, cover art — travels where both formats support it. Protected DRM content cannot be converted legally and is rejected.
Tips for Best Results
- Check the podcast host specification before choosing bitrate — some mandate CBR 64 kbps, others accept VBR up to 192 kbps.
- Preserve ID3 tags by editing them before conversion; Mp3tag and MusicBrainz Picard handle round-tripping cleanly.
- If the W64 is 24-bit studio audio, the SHN at 16-bit is sufficient for listening; higher is wasted on consumer playback gear.
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for SHN and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the W64 container to the SHN container automatically where both formats support them. If a tag field has no SHN equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
Sony Wave64
Source formatWave64 (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.
Shorten Audio
Target formatShorten (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.

Common Use Cases
Share across platforms
Send SHN files to anyone without worrying about whether they have the right software for W64.
Embed in documents
Drop SHN output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
SHN often produces smaller files than W64 for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
