Free Online Audio Tools

AI removes the vocals, finds the lyrics and syncs them word-by-word — sing along in the browser or export a karaoke video.

Isolate the vocals from a song to get a clean acapella.

Remove just the main lead vocal and keep the backing vocals.

Separate a song into individual stems: vocals, drums, bass, guitar and piano.

Upload a song, pick a voice, and hear it sung by a brand-new singer in seconds. The melody, lyrics and timing stay exactly the same.

Upload any recording, clone a voice from a few seconds of audio, and hear yourself transformed in seconds. Works on speech and singing alike.

Turn your voice — or any recording — into an anime voice in seconds. Pick a character or clone any voice you like. Same words, brand-new character.

Restore and clarify vocals that sound dull or low quality.

Cut or trim a section from an audio or video file.

Convert audio between MP3, WAV, FLAC, OGG, M4A, AAC and OPUS.

Extract the audio track from a video file as MP3 or another format.

Apply an equalizer preset to shape the sound (bass, treble, vocal clarity).

Remove silent gaps from an audio file.

Convert audio between mono and stereo.

Merge several audio files into one track, optionally with a crossfade.

Make audio louder without distortion — Auto picks the loudest clean level, or set the exact decibels yourself.

Speed up or slow down audio without changing its pitch.

Shift the pitch (key) of audio up or down in semitones without changing speed.

Reverse an audio file so it plays backwards.

Normalize loudness to a standard level (e.g. YouTube -14 LUFS).

Boost the bass of any track — pick how much low end and which band, from deep sub rumble to punchy kick, held clip-safe by a limiter.

Apply an 8D spatial effect that makes sound rotate around the listener.

Cut a clip from a song and export it as a phone ringtone (M4R for iPhone or MP3).

Apply the slowed + reverb effect (slower tempo plus echo) to a song.

Draw a spectrogram of any track — every frequency over time, as a downloadable image.

Measure a file and get a report: is it really lossless, how loud is it in LUFS, does it clip, where does its spectrum stop.

Turn any track into a waveform picture — pick the size, the colours and a transparent background.

Turn a track of up to 10 minutes into a video: your picture on screen, an optional moving waveform, and an MP4 that YouTube accepts.

Turn up to 90 seconds of audio into a video that moves with the sound: a wave, bars, a spectrum or a stereo scope over your artwork.
