AUDIO REPAIR LAB
Audio Bit-depth Dither Lab
Compare quantization and dithering on quiet passages. Export test files and measurements.
WORKED EXAMPLE

Input, export & project notes
Projects save editable content, controls and source fingerprints. Original binary files remain on your device; reselect them after reopening to regenerate media-dependent results. Downloads may include a bounded proof rather than the full original. Review the method and export labels before delivery.
Using Audio Bit-depth Dither Lab
Compare quantization and dithering on quiet passages. Export test files and measurements.
- Start with Try example to see the audio bit-depth dither lab workflow. Choose compatible local audio files, or listen to the synthetic worked example. Edit explicit time regions, routing or supporting records where present. WAV input retains its declared sample rate when the browser decoder supports it; compressed input may be resampled.
- Use the nearby controls and editable records, then choose the main update button. Undo/redo restores content and settings; keep source media to regenerate file-dependent projects.
- Review the preview, Evidence and Review tabs. Seeded triangular dither before uniform PCM quantization. Noise-shaped dither is not applied.
- Choose Export for the actual task files, report JSON/CSV or the complete ZIP. Save project retains editable content and control settings. Original binary media is not embedded; source fingerprints help identify the files needed when reopening.
Example
The tailored example produces 2 evidence records. Seeded triangular dither before uniform PCM quantization. Noise-shaped dither is not applied.
Questions & answers
What does Audio Bit-depth Dither Lab do?
Compare quantization and dithering on quiet passages. Export test files and measurements. Seeded triangular dither before uniform PCM quantization. Noise-shaped dither is not applied.
What can I open?
Choose compatible local audio files, or listen to the synthetic worked example. Edit explicit time regions, routing or supporting records where present. WAV input retains its declared sample rate when the browser decoder supports it; compressed input may be resampled.
What can I download?
The Export tab lists actual artifacts generated by the current input. A complete ZIP includes task files, evidence, editable content and method notes. Audio processing produces PCM WAV where applicable; music utilities add MIDI or practice WAV; frame workflows include PNG frames and an optional silent, sampled WebM proof. Graphic outputs may include SVG/HTML, and geometry workflows disclose supported OBJ/STL/PLY outputs.
What should I check before using the result?
Seeded triangular dither before uniform PCM quantization. Noise-shaped dither is not applied. Inspect the export in its intended player, engine, editor, printer or delivery workflow. Findings are scoped checks, not certification. Processing stays in the browser; the public site retains approved advertising and optional consent-based analytics.
