How local processing works
Processing uses FFmpeg.wasm locally in this browser. The media engine downloads on first use, but the selected media and result are not uploaded to Tubelexity or a processing server.
Frequently asked questions
Can I cut audio with exact times?
Yes. Enter start and end values to hundredth-second precision.
Can I preview only the selected range?
Yes, when the browser can play the source codec.
Can fades be added to the clip?
Yes. Set independent fade-in and fade-out durations.
Why might the waveform be unavailable?
The browser may not decode that codec through Web Audio even when FFmpeg export can work.
Is audio uploaded?
No. Analysis and export are local.
