AudioTweak is an advanced audio player that helps musicians learn, transcribe, and practice songs. With AudioTweak, you can slow down fast passages, loop and save tricky sections, or shift the pitch into a key that fits your voice or instrument. Whether you're learning a solo, arranging a new part, or trying to hear a hidden bassline, AudioTweak gives you the tools to uncover every detail. You can isolate instruments with EQ, adjust tempo without losing sound quality, and even export your loops to keep practicing anywhere. AudioTweak makes practicing music smarter, clearer, and more enjoyable.
AUDIO SPEED CHANGER
Slow down tricky parts to practice at your own pace, or speed up exercises to build skill—all without affecting sound quality.
PITCH CHANGER
Adjust pitch to play your music in any key, match your instrument, or fit your voice. Explore alternate keys while transcribing or arranging.
AUDIO LOOPER
Repeat and focus on specific sections until you master them. Whether it's a tricky solo or a chord change, looping makes it easy to practice the hard parts as many times as you need. Save a loop with a name and jump straight back to it next time you open the song — the verse, the chorus, and that one awkward bar, always a tap away.
COUNT-IN METRONOME
Start every practice session in the pocket. The built-in count-in metronome gives you a rhythmic lead-in before playback begins, so you're always ready to play along from the first beat.
AUDIO ISOLATION
Use the 10-band EQ to cut out what's not important, and the stereo pan to shift focus between left and right channels. Perfect for isolating guitars, vocals, or other parts that sit to one side of the mix.
