Singium

Sing into your phone and hear yourself in tune, instantly. Singium is a live auto-tune microphone. Plug in or connect a speaker, hit the mic, and your voice comes back polished in real time — no studio, no plugins, no experience needed. Every take you like, you can record, dress up, and share. ONE TAP TO A GREAT SOUND Start with a hero preset and you're done: Natural, Hard Tune, Rap, Angel, Adlib, Vocoder, Choir, or Robot. Or turn on AI Mode and Singium listens to your voice, works out the key you're singing in, and tunes to it automatically. REAL-TIME TUNING THAT SOUNDS LIKE YOU - Pick any key and scale, or let AI Mode find it - Retune speed from natural correction to hard, locked-on tuning - Dry/wet mix so you decide how much is you and how much is the effect - Formant correction keeps your voice sounding human instead of chipmunked HARMONIES AND CHOIRS Add a third, a full triad, or stack a choir behind your lead. Every voice follows the key you're singing in. VOICE AND CHARACTER - Character presets: Clean, Phone, Megaphone, Old Radio, Lo-Fi, Bright - Voice shapes: Robot, Monster, Chipmunk, Giant, Kid, Alien - Vocoder and talkbox tones - Studio polish, saturation, air and growl to finish the sound - Formant slider to shift your voice deeper or brighter RECORD, THEN CHANGE YOUR MIND Every take is saved to your library. Play them back, rename them, share them — and because Singium keeps a clean copy of your voice, you can go back and change the effects on a recording you already made. Try a different key, a different character, a whole different sound, and save it as a new take. STUDIO Lay a take over a beat you import, trim and place both tracks, balance them, and export the mix. AI Suggested Mix & Master sets the levels for you in one tap. MADE FOR SHARING Export a vertical video with a live visualizer, ready to post. Share audio as .m4a. Send your exact sound to a friend as a sound pack and they can sing through the same setup. TOOLS FOR SINGERS - Pitch ribbon showing your notes as you sing - Take scoring, so you can see how close you landed - Range finder to work out your vocal range and voice type - Hum a melody and export it as MIDI - Loop pedal, sing-over-a-beat with count-in and metronome, and take comping Singium is free. A note on sound: for live monitoring, a wired speaker or headphones will always beat Bluetooth. Bluetooth adds delay that no app can remove.
