Tonify by Musestar - Vocal Remover & Stem Isolation

Isolate vocals & stems from any video. Transpose the key, mix with a full EQ, adjust speed, loop & record. By Musestar.

Tonify by Musestar — Vocal Remover, Pitch Shifter, Speed Changer & Audio Looper for Any Video Tonify turns any video or audio in your browser into a full music practice studio. Isolate vocals and instrumentals, transpose the key, change speed without changing pitch, loop any section, and mix with a built-in EQ — all in real time, on YouTube, SoundCloud, and virtually any site that plays audio. Built for guitarists, singers, producers, DJs, karaoke fans, music teachers, and anyone learning a song by ear. ─── VOCAL REMOVER & STEM ISOLATION ─── Split any track into vocals and instrumental with one click — a true vocal remover and stem separator built into your browser. Perfect for karaoke, acapella practice, remixing, or transcribing a bassline. Record a clip from your microphone, the browser tab, or the pitch/speed-adjusted Tonify output, then let AI-powered stem isolation separate the parts. Download the isolated vocal and instrumental stems individually. 4-way stem splitting (vocals, drums, bass, guitar/other) is coming soon. ─── TRANSPOSE & PITCH SHIFTER ─── Change the key of any song by semitones in real time, with no effect on playback speed — a true pitch shifter and key changer for singers and guitarists. Use the cents control for micro-tuning beyond a full semitone, ideal for matching a guitar that's slightly out of standard tuning or singing in a more comfortable key. ─── SPEED CHANGER — SLOW DOWN OR SPEED UP AUDIO ─── Slow down fast solos, tricky riffs, and rapid vocal runs without changing pitch, or speed up playback for sight-reading and ear-training drills. Adjustable from 0.25× to 3× speed, independent of the pitch shifter — so you can slow a song down and still hear it in the original key. ─── LOOP — A/B REPEAT FOR PRACTICE ─── Set A and B loop points to repeat any section of a song on autoplay. Choose a fixed repeat count or loop infinitely. An essential audio looper for drilling a difficult passage, building muscle memory, and locking in timing. ─── CLIP RECORDER ─── Record audio from three sources: your microphone (capture yourself singing or playing along), the browser tab (record straight from the page), or the Tonify-processed output (pitch-shifted and speed-adjusted). Use it as a standalone audio recorder, or feed clips directly into stem isolation. ─── TIMELINE PLAYBACK ─── Mark a time range on any video and Tonify will automatically swap in the isolated vocals or instrumental for that section, then switch back to the full mix — hands-free, and it keeps working even with the popup closed. ─── BUILT-IN MIXER & 5-BAND EQ ─── Shape the sound with Bass (120 Hz), Low Mid (250 Hz), Mid (1 kHz), Hi Mid (4 kHz), and Treble (12 kHz) bands. Boost bass, carve out space for vocals, or dial in your ideal listening mix. Stereo/mono toggle and left-right balance make it easy to isolate instruments panned to one side of a mix. ─── SETTINGS MEMORY ─── Tonify remembers your pitch, speed, EQ, loop, and isolation settings for up to 20 videos — come back to a YouTube video later and everything's exactly how you left it. ─── CLEAN, MINIMAL INTERFACE — DARK & LIGHT ─── A refined black-and-white interface with full dark and light mode, plus three visual styles to match your taste — from crisp and modern to a warm classic look. Whether you're transcribing a solo, practicing karaoke, slowing down a tricky passage, or just want a quick pitch shifter and vocal remover for YouTube, Tonify gives you studio-grade control without leaving your browser.
