Converting MP3 to WAV, keeping only part of a recording, changing its level or joining several files are common tasks. Bethemesh performs these operations directly in the browser and can combine them in the Workspace, so a one-off task stays simple while a repeated workflow becomes a reusable pipeline.
Choosing an audio format
A filename extension alone does not convert audio. The source must be decoded and a new stream encoded. The audio converter supports common outputs including MP3, WAV, FLAC, OGG, M4A and Opus, with additional formats accepted as input.
MP3 is compact and broadly compatible. WAV is convenient as a working PCM format. FLAC compresses without loss and suits archives. OGG Vorbis and Opus are open, efficient codecs, while M4A/AAC is common in mobile and multimedia ecosystems.
Convert locally
Choose a file in the audio converter, select the output and start conversion. FFmpeg/WebAssembly is loaded on demand for formats that need it, while the audio itself remains processed on your device. Examples include MP3 → WAV, WAV → FLAC, FLAC → MP3, MP3 → OGG or Opus, and WAV → M4A.
Trim, adjust volume and merge
Use Audio trimmer to remove silence or keep a precise interval. Use Audio volume adjuster to raise or lower gain, taking care not to clip peaks. Use Audio merger to concatenate several sources—even when their formats differ—into one result.
Why build an Audio pipeline?
Separate tools can require repeated download and re-import steps. In the Workspace, a chain can instead be:
Import several audios → Merge → Adjust volume → Convert to MP3 → Download
For one file:
Import audio → Trim → Adjust volume → Convert → Download
The Workspace only proposes modules compatible with the current resource type, and Audio templates provide useful starting recipes.
