WAV Converter

Convert any audio to 3CX-ready WAV format. Free on every plan.

/dashboard/tools/wav-converter (and the public-facing version at sikurd.com/wav-converter) converts any audio file to the format 3CX requires for prompts + hold music: WAV, 8 kHz, 16-bit, mono, μ-law (or PCM).

How to use

  1. Drag a file onto the dropzone (or click to pick from your file system).
  2. Sikurd processes locally in your browser — nothing uploads to a server.
  3. Download the converted file.

Supports: MP3, M4A, AAC, OGG, FLAC, WAV (re-converts), WEBM. Up to 100 MB.

Format details

3CX expects:

  • Sample rate: 8000 Hz (8 kHz).
  • Bit depth: 16-bit.
  • Channels: mono.
  • Encoding: μ-law (CCITT G.711) or PCM.

Sikurd produces μ-law by default since it's the safest cross-version choice. PCM also works on most builds — toggle in the converter's "Advanced" panel.

Privacy

Conversion happens entirely in the browser via the Web Audio API. The audio file never leaves your machine. This is the only Sikurd tool that's free to anyone — no account required, no quota.

Bulk conversion (planned)

Multi-file drag-and-drop with batch download is on the roadmap.
