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.
Allow it and the recording happens in this tab alone. It is never sent anywhere.
Or drop an audio file
Speech or music. Reverb, delay, chorus, flanger, EQ, compressor, fade and normalisation, in the order you set.
Everything happens in this tab. The file is never uploaded anywhere.

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.
Vocoder
Dudley’s channel vocoder: splits a voice into N bands, follows each band’s envelope and paints it onto music or a built-in synth drone. Controls for band count, attack, release, formant tilt, sibilance pass-through and dry/wet.
Pitch Correction
Detects a monophonic vocal’s pitch with YIN, snaps it to a chosen key and scale, and resynthesises with TD-PSOLA so the formants stay put. The retune-speed control runs from natural correction to the hard-tuned staircase; the detected pitch track is drawn.
Centre-Channel Cancel
Subtracts what is identical in both channels, band-limited so the bass and the top survive. This is not stem separation: it removes the centred kick, bass and snare along with the vocal, leaves any stereo reverb behind, and does nothing at all to a mono file — which it detects and refuses up front.
Next
These accept what this tool produces, so the result can go straight in.
Loudness Normaliser
Measures integrated loudness and true peak, then normalises to a target LUFS such as -14 or -16.
Audio Trimmer
Cuts a section out of an audio file on the waveform, with fade in and fade out.
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.

Audio Converter
Converts between MP3, WAV, FLAC, AAC, OGG and Opus with bitrate and sample-rate settings.
Extract Audio from Video
Pulls the audio track out of a video as MP3, WAV, M4A or FLAC, or copies it without re-encoding.
