What this tool preserves
- Every selected source sample and the complete decoded duration.
- The original sample rate, with no resampling.
- One source channel per mono output, with no downmix or matrix.
- No gain, normalization, clipping, phase inversion, or source separation.
- A JSON manifest mapping each source channel and index to its output, sample count, rate, format, and representation changes.
Only upload recordings you have the right to process. Files and generated outputs are retained temporarily for processing and download, then removed automatically.
