Real example files for testing — documented, paired, free.
A library of purpose-built example and test files. 294 files across 11 categories, each with an exact spec sheet and clean-versus-messy pairs.
Generated, not collected
Every file is produced by a deterministic script, so it ships with an exact spec sheet and zero copyright exposure.
Documented, not dumped
Each file page lists its precise properties — noise sigma, silence timestamps, form fields, encodings, seeds.
Paired, not isolated
Clean↔noisy, colour↔greyscale, source↔scanned. Pairs are exactly what serious testing needs.
