开始前需要了解
- Browser-worker processing
Audio files stay in the tab and its worker; TOOLGRID does not expose a server-side audio upload or processing API.
- Format-aware choices
Use MP3 for compact delivery, WAV for an uncompressed working copy, or Ogg when that container matches the playback environment.
- Queue and cancellation states
Every encoding job exposes loading, progress, error, retry, and worker termination rather than leaving a tab in an unknown state.
- Honest boundaries
Fast merge requires compatible tracks, lossy conversion cannot restore detail, and tempo processing can introduce audible artifacts.
常见问题
Is audio uploaded?
No. Selected files are processed in the browser worker and are not submitted to a TOOLGRID processing endpoint.
Should I choose MP3 or WAV?
MP3 is smaller and widely playable but lossy. WAV is much larger and useful as an uncompressed intermediate. Converting an already lossy source to WAV does not restore lost detail.
Why can merge fail?
The fast concat path expects matching codec, sample rate, channel layout, and container characteristics. Convert sources to one shared preset before merging when they differ.
Does speed change preserve pitch perfectly?
The tempo filter aims to keep pitch near the source for 0.5× to 2× changes, but artifacts can occur. This is not a music-grade time-stretching workstation.
