Voice Studio — Autotune & Voice Changer

Voice Studio is a free browser recording booth with pitch correction built in. Tap the red button, sing or talk, and the tool listens to the pitch of every moment of your voice and nudges it onto the nearest correct note of whatever key and scale you have chosen. Push the retune speed all the way down and the correction becomes instant, which produces the hard, stepped, robotic singing sound made famous on modern pop and hip-hop records. Slide it up and the correction glides between notes the way a trained singer does, so the result just sounds like a better version of you.

Correction is only the start. A full effect rack sits underneath: pitch and formant shifting that can turn you into a chipmunk or a giant, character voices including robot, telephone, old radio, megaphone, 8-bit, whisper, monster and underwater, reverb from a small room to a cathedral, tempo-synced echo, stereo width, compression, a noise gate and a de-esser. Automatic harmonies can stack a third, a fifth, an octave below, or a full choir on top of your take — and because they follow the key and scale rather than a fixed number of semitones, they stay in tune with the song instead of drifting out of it as the melody moves.

You can sing to something, too. Seven backing styles — lo-fi, trap, piano ballad, EDM, desi, reggaeton and acoustic — are generated live in your browser from oscillators and noise, so they are original, royalty-free and adjustable in tempo and key. You can also drop in your own instrumental MP3. The music is never captured through your microphone; it is mixed in at export, which keeps your vocal clean and lets you rebalance the two afterwards. Finish by downloading a WAV or MP3, or by rendering a short vertical video with an animated waveform card so the clip can actually be posted to Reels, Shorts, TikTok or a WhatsApp status, since those platforms will not accept a bare audio file.

Everything above runs on your own device. Your voice is never uploaded, never stored on a server and never used to train anything — there is no account, no watermark and no limit on how many takes you record. Sharing hands the finished file straight to the app you pick using your phone's own share sheet, so the recording goes from your device to your friend without passing through us at all.
