Fonctionnement
The file stays in your browser. The shared Bethemesh audio engine applies the transformation with FFmpeg/WASM and generates a result that can be downloaded or reused in Workspace. The same shared operation powers the public tool, widget and Workspace pipelines, keeping behavior consistent across every Bethemesh surface and reusable audio workflow.
Use the same transformation in Workspace to process audio collections.
Prepare a file quickly before editing, publishing or archiving.
The source file stays in your browser throughout the operation.

Bethemesh accepts its supported audio formats and processes the result locally in the browser.
Understand sample rate, why 44.1 kHz and 48 kHz are common, and when converting an audio file sample rate is actually useful.
Combine trimming, channels, sample rate, normalization, compression and export into a clear, reusable audio processing pipeline.
Convert, trim, adjust volume and merge MP3, WAV, FLAC, OGG, M4A or Opus files, then combine these operations in a pipeline.
Understand speed changes, fade-ins, fade-outs and audio reversal, with practical advice for editing and reusable browser workflows.
