Lossless and private by design
- Validates FILE, TRACK, INDEX, CD-frame timing, pregaps, ordering, and duration bounds.
- Rejects multi-file sheets, data tracks, traversal paths, device names, corrupt audio, and ambiguous filename matches.
- Preserves codec, sample rate, channels, bit depth, tags, and exact decoded PCM for every exported track.
- Uses same-codec lossless re-encoding when exact sample cuts cannot be safely stream-copied; the manifest states this explicitly.
- Outputs a normalized UTF-8 CUE and, when splitting, a ZIP of complete tracks.
Only upload recordings you have the right to process. Uploaded files are retained temporarily for processing and download, then cleaned up automatically.
