The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

shn

Shorten (SHN) is a lossless audio compression codec created by Tony Robinson at SoftSound and first published in 1993, making it one of the earliest practical lossless compressors. The algorithm uses linear prediction to estimate each sample from predecessors, then encodes residuals with Huffman or Golomb-Rice codes. Compression ratios typically fall between 2:1 and 3:1, with the guarantee that decoded output is bit-identical to the original. Shorten gained cultural significance in the late 1990s as the preferred format for trading live concert recordings online — communities like etree.org built entire distribution networks around SHN files, and bands like the Grateful Dead and Phish tacitly endorsed the practice. One advantage was the format's simplicity: encoding and decoding ran fast even on modest Pentium-era hardware. Another strength was deterministic output — the same input always produced the same bytes, making checksums reliable for verifying integrity across thousands of traders. While FLAC eventually superseded Shorten with better compression, seeking support, and embedded metadata, SHN retains historical importance and extensive live music archives in the format still circulate today.

wav

WAV (Waveform Audio File Format) is an uncompressed audio container jointly developed by Microsoft and IBM, first published in August 1991 alongside Windows 3.1. Built on the Resource Interchange File Format (RIFF), WAV stores audio data — most commonly as linear pulse-code modulation (LPCM) — together with metadata describing sample rate, bit depth, and channel count. This straightforward structure has made WAV the de facto standard for uncompressed audio on Windows and a universally accepted interchange format across virtually every operating system, audio editor, and media player in existence. CD-quality WAV files use 16-bit samples at 44.1 kHz stereo, while professional workflows routinely employ 24-bit or 32-bit float samples at rates up to 192 kHz. A major advantage is zero-loss fidelity: because standard WAV applies no compression, the stored data is an exact digital representation of the original recording, making it the preferred choice for mastering and archiving. WAV also supports embedded metadata through INFO and BWF chunks, enabling timestamping and production notes. The main trade-off is file size — one minute of CD-quality stereo occupies roughly 10 MB — and the 32-bit RIFF structure imposes a 4 GB limit, though RF64 removes that ceiling.

Frequently Asked Questions

Why convert SHN to WAV?

WAV is the standard uncompressed format for audio editing. Converting SHN to WAV gives you raw PCM data ready for any DAW or editor.

Is the conversion lossless?

Completely. SHN is a lossless codec, and WAV stores uncompressed PCM — the decoded audio is bit-for-bit identical to the original.

Will the WAV files be much larger?

Yes — uncompressed WAV is several times larger than compressed SHN. A 30 MB SHN file may produce a 100+ MB WAV.

What software handles WAV best?

Audacity, Adobe Audition, Logic Pro, Pro Tools, FL Studio — every professional DAW works perfectly with WAV files.

Can I decompress many SHN files at once?

Yes — upload a batch of SHN files and convert them all to WAV simultaneously for rapid archive decompression.

Is the conversion secure?

SHN uploads are removed right after processing. WAV files are auto-deleted from our servers within 24 hours.
