Reverse Engineering Rock 'n' Roll

Capo uses a blend of advanced signal processing and machine learning to help you learn songs by ear. Its powerful, simple-to-use tools allow you to dig deep into the details of a recording so you can learn to play songs more accurately, and in less time.

Hear notes more clearly

Slow it down, solo instruments, and listen to quickly-played notes frozen in time.

Start playing songs faster

Automatically detected chords and beats give you a massive head start on learning new tracks.

Pick up where you left off

Capo's Projects store the changes you make to chords, looping regions, and even the playhead location for when you return.

Tab It Out, Hear Each Note

Use your mouse to draw notes inside the spectrogram. As you click and highlight each note, hear it played back as tablature is generated automatically for you—no need to keep a notepad at hand to transcribe solos.

This App is so bleepin' awesome

★★★★★

A musicians essential tool! I have learned deep dives into so many licks, genres and transcribing every kind of tune. This is the best I've found. And the isolation algrhythm you can key in on any mix and pick out any part you are trying to comp. It's a truly Baddass piece of software. I use it to load samples into my Nord as well. You can make a region, tune it by cents or by half steps, then export any length of region. and load it into a sampler. Beyond fives stars as far as I'm concerned.

Great learning tool

★★★★★

I play the wooden Irish flute, and it is great to use Capo to slow down tunes while maintaining pitch. I also use the looping of small sections to grasp complex parts. In addition, I have flutes in multiple keys. The standard Irish flute is in the key of D. But sometimes I want to play and learn a tune on my E flat flute, and Capo allows me the change the pitch on a recording which I often do - i.e changing the pitch from D to E flat to accommodate my E flat flute (or E flat whistle). Thanks for a great product.

“Whether I go to learn a song myself or teach someone how to play a song, I bring it up in Capo.”

Read about Capo's use in Education ›

Capo is a fantastic way to analyze & learn music quickly; I love how clean the pitch algorithm is even at 1/4 speed. Capo is a great teaching & learning tool whether you're a rank beginner or a seasoned professional.

I have been wishing for this software for years. It's incredibly useful, whether I'm charting my own songs for the players who join me, or discovering exactly what is being played on a recording I love.

I am a devout Capo user for a couple of years now—it's the GREATEST of all, especially since it makes a library of your tunes you work on and is sonically great. It's my go-to music learning app!

Capo is an invaluable learning tool. I use it to loop hard phrases, and slow them down with very few artifacts, making them easy to master!
