WaveCraft

About the Telephone & Radio Filter

A resonant filter with creative presets (telephone, radio, underwater) and corrective ones (rumble, mains hum).

How to use it

  1. Drop an audio file (MP3, WAV, M4A, OGG, FLAC) or a video into the box.
  2. Pick a preset or adjust the controls — filter type, frequency and resonance. Hit play to hear it live and use “Compare” to hear the original.
  3. Download as MP3 or WAV. Nothing is uploaded: the processing runs on your device.
