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.
Allow it and the recording happens in this tab alone. It is never sent anywhere.
Or drop an audio file
One person singing, no backing track. A chord or a backing track underneath leaves no single pitch to find, and the result comes out rough.
Everything happens in this tab. The file is never uploaded anywhere.

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.
Video Converter
Reads MP4, MOV, WebM and MKV and writes MP4 (H.264 + AAC) or WebM (VP9 + Opus) with quality and resolution settings. When only the wrapper changes — MOV to MP4, MKV to WebM — the streams are copied untouched.
Video Compressor
Re-encodes to a target file size or a quality preset, stepping the resolution down when the bitrate would starve it, and shows the projected size before it starts and the actual size after.

These accept what this tool produces, so the result can go straight in.
BPM Detector
Estimates a track’s tempo in BPM by onset autocorrelation, with a confidence score and alternative candidates.
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.
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 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.
