Bootleg Toolbox

Bootleg Toolbox is a desktop program for collectors of lossless concert recordings. It covers the everyday jobs we use Trader's Little Helper for, and adds a few things TLH never had. TLH hasn't been updated since 2020.

One file, nothing to install, entirely coded in Rust. It's a single executable for Windows and Linux. You don't need flac, shntool, ffmpeg or LAME: every decoder and encoder is built in.

What it does

• Reads FLAC, WAV (integer and float), SHN, APE, WavPack, ALAC, plus MP3, MP2 and AAC (always flagged as lossy), M4A/MKA, and the audio track of MP4 concert videos.
• Checksums: verify and create FFP, ST5, MD5 and SFV. Checksum files made on Windows (backslash paths, Windows-1252 names) are read correctly.
• Decode test of every file, and Details: CD-ready, MD5 signature present, sector boundary errors (SBE).
• Torrents for DIME and TTD, private, each with its own source tag so you can seed on both sites at once, plus any other tracker you add. You can also check a show against its .torrent, piece by piece.
• Conversions: to FLAC (each file decoded again and verified), to WAV, and MP3 copies (320 CBR or V0) in a separate folder. SBE fix, with the same audio as shntool fix.
• Lossless? A spectral analysis that spots MP3/AAC transcodes, upsampled audio, fake 24-bit and lossyWAV, and recognises FM broadcasts instead of calling them lossy. It also searches for the rounding traces MP3 and AAC encoders leave, which catches transcodes even from 320 kbps. Every verdict comes with a full report of the measurements and the reasoning.
• Speed? Estimates whether a tape runs fast or slow, from the FM pilot tone, the tuning against A440 and the mains hum.
• Tag and rename from the info file: artist, date, venue and titles are read from the show's .txt. You check and correct them in a window, then they're written as FLAC tags, with optional renaming. The audio is never touched, so FFP/ST5 stay valid, and it can be undone.
• Setlists from setlist.fm, with your own free API key, ready for tagging.
• DVDs: each title is listed with its audio tracks marked lossless (LPCM) or lossy (AC-3, DTS, MPEG). Extract DVD audio gives you one FLAC file per title from LPCM, bit for bit, or the original stream for lossy tracks. A MediaInfo-style summary is ready to paste into a post.
• Spectrograms, WAV header clean-up, one-click copy of the FFP or info file for upload forms, and an optional "Open in Bootleg Toolbox" entry in the right-click menu.

Safe by design

• Your originals are never modified: conversions, MP3 copies and SBE fixes write new files. Only Tag and rename changes files in place, after you've checked it, and only tags and names.
• No network access unless you ask: an optional update check, and setlist.fm when you request a setlist.
• Open source (GPL-3.0), with every release built by GitHub Actions, SHA-256 checksums and build provenance attestations.
