Learn any song the way you actually practice it. StemScriber pulls a song apart into its separate instruments so you can hear exactly what you're trying to play — then slows it down so you can keep up. What it does: • Isolate any instrument — mute the vocals and band, solo just the guitar (or bass, drums, piano, vocals). Finally hear the part that was buried in the mix. • Slow it down — drop the tempo without the pitch turning to chipmunks. Sit with a fast riff at half speed until it's under your fingers. • See the chords — a chord chart is generated for the song so you can follow the changes while you play. • Tuner + fretboard — built-in, free, no sign-up. Made for the way musicians really learn — by ear, slowed down, one part at a time. Whether you're working up a cover, learning a solo, or figuring out a bass line, StemScriber gets you from hearing it to playing it faster. Use it with music you own or have the rights to. Chord detection is a strong starting point, not a perfect transcription — it gets you playing fast, and you can trust your ears for the rest.

About

Melody Eraser

Read full description

Turn your favorite songs into your own practice backing tracks (minus one). Works on vocals - and on lead instruments like violin or saxophone. The stereo image stays intact. Your music never turns mono. # WHO IT'S FOR - Instrument players who want play-along backing tracks without the lead melody - Anyone transcribing music who wants to isolate the melody and learn it by ear - Singers who want vocal-free tracks for karaoke practice # FEATURES - Just move the slider while the song plays: fade the melody anywhere from 0 to 100% - Keeps the stereo field of the original. Unlike classic "left minus right" cancellers, the result never collapses to mono - Melody Solo mode: listen to just the removed melody - a big help for transcription - New TYPE-I+PF engine: removes the melody while protecting the drums, so snare and hi-hat stay in the mix for a more natural backing track (devices with 6 GB of memory or more) - Seek bar, plus adjustable bass protection that keeps the kick and bass line safe - Everything runs on your device. Your music never leaves your phone # EXPORT Save the result as m4a / ALAC / wav, exactly as you hear it. Title and other track info are carried over from the original file. # MELODY ERASER PRO (one-time in-app purchase) - No ads - Unlimited exports - Background playback (keeps playing with the screen off, with lock screen controls) - TYPE-I+PF without ads # SUPPORTED AUDIO - Your own music files (m4a / mp3 / wav / ALAC / AIFF / FLAC) - Stereo (2-channel) files only - DRM-free files only - Songs purchased from the iTunes Store work as-is (they are DRM-free) - Songs downloaded from music subscription services will not work (DRM-protected) # PLEASE NOTE Results vary by song and mix. If the melody sits off to one side of the stereo field, the effect may be limited. Try the free demo track first. TYPE-I+PF converts each song once (this takes from tens of seconds to a few minutes). In the free version, the conversion runs in the background while one ad plays. With Pro there are no ads, and the conversion runs in the background while you listen.
