We build focused tools that help you slow down songs, change pitch, remove vocals,
play piano online and generate precise tones —
without complicated audio software.

We design our tools around everyday musical work: practicing along with recordings, preparing teaching materials, running rehearsals, building karaoke tracks or checking sounds before a show.
Instead of large, general-purpose audio software, each tool focuses on a single job and stays out of your way. You can combine them as needed: remove vocals, change key, slow things down and play parts on the piano — all in the same browser.
Every product is actively maintained and available in trusted stores, so you always install from a familiar place: the Chrome Web Store or the App Store.
Our browser tools are published in the Chrome Web Store and are meant for modern Chromium-based browsers on desktop, such as Google Chrome and Microsoft Edge. For working with your own audio files on a computer, we offer separate Mac apps that you install from the App Store.
No. The extensions work directly with the websites and tabs open in your browser, and the Mac apps work with audio on your computer. The tools are designed for practical, real-world use without unnecessary steps, and all the processing happens in real time on your device.
The tools include a free trial period so you can see if they fit your workflow. After that, you can choose from subscription or one-time purchase options where available. Exact prices are always shown inside of the product before the checkout.

Our tools are designed for anyone working with music: singers, instrumentalists, choirs, bands, music schools, home-studio producers, DJs and content creators who use music in their videos or streams.
