Noise Remover
Removes hiss, hum and room noise with spectral gating: a noise profile from a marked region or the quietest tenth of the recording, subtracted per frequency band with a stated floor. Reads audio files and the audio track of MP4/WebM; writes WAV, M4A or Opus.
Drop a recording to clean up
MP3, WAV, FLAC, OGG, M4A, or the audio track of an MP4 or WebM. A noise profile is taken from a quiet stretch, then hum, hiss and room noise are subtracted band by band.

Remove Audio
Strips the audio track from a video without touching the video stream.
Loudness Normaliser
Measures integrated loudness and true peak, then normalises to a target LUFS such as -14 or -16.
Voice Changer
Shifts pitch and formants independently, so a recording reads as a different person rather than as a sped-up tape. Presets for male↔female, child, giant, helium, robot (ring modulation), telephone (300–3400 Hz band) and whisper (noise excitation). Records from the microphone or takes a file; writes WAV.
Audio Effects Rack
A chainable rack in one page: reverb by convolution with generated impulse responses, delay, chorus, flanger, EQ, compressor, fade and peak normalisation. The order of the chain is editable, because it changes the result.
