HOW TO CONVERT SHN → SND
Give us the SHN
Select a SHN (or several for batch). We read the header to pick decoder settings automatically.
Re-encode to SND
The audio is decoded, optionally resampled, and re-encoded as SND at transparent default bitrate.
Retrieve your SND
Grab the download as soon as it is ready. Typical jobs finish in seconds for short clips.
SHN is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. That is why users land on this page looking for a SND copy. Turn your SHN audio into a widely-supported SND file. The conversion happens server-side through FFmpeg — the same engine behind every major audio editor — so the output plays cleanly on phones, car stereos, DJ software and streaming tools. One more beat. SHN is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. Receiving format: SND is an audio format with specific trade-offs between file size, bitrate flexibility, and device support.
Why convert SHN to SND
The motivation for a SHN → SND conversion is almost always practical: a playback device, hosting platform or editing suite that insists on SND. The audio quality trade-off is controllable via bitrate; the compatibility win is immediate and unambiguous.

SHN vs SND — Strengths and limitations
What each format does best, and where it falls short.
SHN Strengths
- Lossless.
- Historical artifact of 1990s music trading.
- Modern decoder availability.
Limitations
- Historically royalty-encumbered.
- Obsolete for new recordings.
- FLAC offers better compression.
SND Strengths
- Historical NeXT archive format.
- Compatible with Sun AU.
- Simple header structure.
Limitations
- Legacy — no new content.
- Ambiguous — NeXT .snd and Mac .snd are different formats.
- Requires specialized tooling for Mac resource-fork variant.
Quality & Compatibility
The SND output is as good as the SHN source allows. If the SHN was encoded at 96 kbps, the SND cannot reconstruct detail the encoder already dropped; picking a very high SND bitrate just produces a larger file. Match SND bitrate to the SHN quality for the best balance.
Tips for Best Results
- Sample-rate mismatches between SHN and target device (48 kHz phone output from a 44.1 kHz track) are handled automatically; no manual resampling needed.
- For audiobook delivery, match the platform spec exactly — ACX requires 192 kbps CBR 44.1 kHz stereo, for example.
- Batch-convert an album in one job so every track shares identical encoder settings and loudness normalisation.
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 SND 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 SHN container to the SND container automatically where both formats support them. If a tag field has no SND equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
Shorten Audio
Source 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.
NeXT Sound
Target formatSND (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.
Going the other way? Convert SND back to SHN with the same engine.
Common Use Cases
Share across platforms
Send SND files to anyone without worrying about whether they have the right software for SHN.
Embed in documents
Drop SND output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
SND often produces smaller files than SHN 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.
