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.
Allow it and the recording happens in this tab alone. It is never sent anywhere.
Or drop an audio file
The voice goes first. Only its loudness per frequency band is measured, and that shape is painted onto whatever music you choose below.
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.
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.
Video Editor
Assembles clips into a YouTube or Shorts upload in the browser: trim, order, transitions, a music bed and subtitles. Same-batch AI clips with hard cuts export losslessly without re-encoding.
Video Trimmer
Cuts a clip between two timestamps, copying streams without re-encoding when the cut is on a keyframe.

These accept what this tool produces, so the result can go straight in.
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.
Audio Joiner
Joins audio files end to end or mixes them onto one timeline with per-track gain.

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.
Audio Trimmer
Cuts a section out of an audio file on the waveform, with fade in and fade out.
