Fast, secure TTA to SHN conversion. No registration required.
Setup: TTA is the True Audio lossless codec, fast to decode on low-power devices. Goal: an interchangeable SHN. Moving audio from TTA into SHN is a routine job for podcasters, musicians, transcribers and anyone who needs a file to play somewhere the original would not. KaijuConverter reads the TTA once, re-encodes through FFmpeg at the bitrate you choose, and returns a polished SHN in seconds. Worth knowing: TTA is the True Audio lossless codec, fast to decode on low-power devices. Meanwhile SHN is an audio format with specific trade-offs between file size, bitrate flexibility, and device support.
True Audio Lossless
Source formatTTA (True Audio) is an open-source lossless audio codec that provides real-time lossless compression with hardware-friendly decoding. It achieves compression ratios similar to FLAC while maintaining very low CPU requirements during playback.
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.
Why convert TTA to SHN
The motivation for a TTA → SHN conversion is almost always practical: a playback device, hosting platform or editing suite that insists on SHN. The audio quality trade-off is controllable via bitrate; the compatibility win is immediate and unambiguous.
HOW TO CONVERT
TTA → SHN
Give us the TTA
Select a TTA (or several for batch). We read the header to pick decoder settings automatically.
Re-encode to SHN
The audio is decoded, optionally resampled, and re-encoded as SHN at transparent default bitrate.
Retrieve your SHN
Grab the download as soon as it is ready. Typical jobs finish in seconds for short clips.
Common Use Cases
Cross-platform music libraries
Moving libraries between iTunes, foobar2000 and Plex is smoother when tracks are standardised on SHN.
Streaming uploads
SoundCloud, Bandcamp and YouTube Music accept SHN directly; TTA triggers a transcoding step and a delay.
Legacy hardware playback
Older car head units, portable players and boomboxes often decode SHN exclusively — a lasting compatibility guarantee.
Ringtones and notifications
iOS, Android and Windows all accept SHN as a system sound or custom ringtone with no further conversion.
TTA vs SHN — Strengths and limitations
What each format does best, and where it falls short.
TTA Strengths
- Lossless bit-exact reproduction.
- Fast, low-memory decoding.
- Open-source reference.
- Cue-sheet support.
Limitations
- Compression ratio worse than FLAC.
- Niche tooling.
- Hardware support died with 2000s DAP era.
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
The SHN output is as good as the TTA source allows. If the TTA was encoded at 96 kbps, the SHN cannot reconstruct detail the encoder already dropped; picking a very high SHN bitrate just produces a larger file. Match SHN bitrate to the TTA quality for the best balance.
Tips for Best Results
- Sample-rate mismatches between TTA 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 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 TTA 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.
