Horror Ambient Sound Mixer

Mix rain, thunder, wind, footsteps, forest night and low drones into your own background soundscape for reading, writing or games.

Scary Soundboard

Tap to play creaking doors, heartbeats, knocks, whispers, chimes and more, synthesised on the spot. Search, loop and adjust volume.

Ghost Voice Effect Maker

Record your voice or open an audio file and turn it into something not quite human with echo, reverb, distortion and pitch.

Reverse Audio Generator

Play any recording backwards. Open a file, preview it reversed and download the result.

Creepy Sound Effect Maker

Design unsettling tones from scratch: oscillator, pitch sweep, wobble, echo and distortion, then export a WAV.

Audio Spectrogram Viewer

See any recording as a waveform and a spectrogram, scrub along the timeline and read the frequencies at any point.
