Multi-Segment Batch Export
Detect active ranges and package multiple decoded segment WAV files plus a JSON manifest into one browser-generated TAR archive.
Choose a browser-decodable audio file.
Why TAR is used
This browser-local implementation creates a simple TAR archive itself, so MesraTools does not advertise ZIP when a ZIP library is not actually present. The archive contains numbered PCM WAV files plus a JSON manifest.
Resource guidance
Batch export duplicates decoded audio into new WAV data and can consume substantial browser memory. Use modest files and segment counts, especially on mobile devices. Build 120 caps one package at 50 segments.
Format implications
Each output is a new 16-bit PCM WAV rendered from decoded samples. It is not compressed-codec stream copy and may be much larger than the source.
Privacy
The selected file is decoded and processed locally in the browser by this Build 120 tool; it is not intentionally uploaded to MesraTools.
Limitations
Silence and segment boundaries are threshold-derived editing evidence, not semantic chapters or speaker turns. Browser memory and codec support vary by device. Generated WAV/TAR/text files do not preserve every source metadata field.
