Slow down, loop, and learn songs with audio analysis tools

Capo for Mac

Capo for Mac

  -  Demo
Capo for Mac is a specialized music practice and transcription app designed for musicians who want to learn songs by ear, slow down difficult passages, detect chords, and isolate instruments more easily.

Instead of relying on tabs or sheet music, Capo for macOS helps users break a song into manageable parts using waveform and spectrogram views, tempo adjustment, pitch shifting, chord recognition, and playback looping.

It is aimed primarily at guitarists, bassists, singers, ukulele players, mandolin players, and anyone serious about ear training or song study.

Capo is distributed through the Mac App Store and works with local, non-DRM audio files such as MP3, M4A, AIFF, WAV, and iTunes Plus tracks.

Key Features

Chord Detection – Automatically identifies chords in songs, including support for guitar, bass, mandolin, ukulele, and even 5-string bass arrangements.

Tempo Adjustment – Slows down or speeds up audio so you can study difficult phrases without changing the musical character too dramatically.

Pitch Shifting – Lets you transpose tracks into a friendlier key for singing, practicing, or easier instrumental study.

Instrument Isolation – Helps solo or mute certain sound sources and narrow frequency ranges so you can hear parts more clearly.

Spectrogram Editing – Allows users to visually inspect audio and mark notes by drawing over the spectrogram for transcription work.

Loop Practice – Makes repeating tricky sections easy, which is useful for solos, riffs, vocal lines, and rhythm practice.

Project Sync – Capo Pro can save projects and sync changes across devices, while Platinum extends feature access to iOS as well.

User Interface

It has a purpose-built interface that feels more like a musician’s workshop than a standard media player.

The app combines waveform visualization with harmonic and pitch-oriented tools, making it ideal for close listening and detailed study.

Its layout is clean, but it may initially look technical to beginners who have never used spectrograms or transcription tools.

Once understood, however, the interface becomes one of Capo’s strongest advantages because it presents musical structure visually rather than forcing users to work only by ear.

Apple has also highlighted Capo as an Editors’ Choice music app, which reflects the maturity and polish of its design.

Installation and Setup

Installing Capo for Mac is straightforward. You download it from the Mac App Store, launch it, and then import an unprotected audio file from your local library.

From there, the app analyzes the song and begins presenting beats, chords, and key-related information. Users who want full editing functionality, project saving, and access to advanced views will need an active subscription.

According to the official listing, the app currently offers yearly subscription tiers for Mac-only use and a higher Platinum tier for Mac plus iOS access.

How to Use

Open the app and drag in a supported local audio file such as MP3, M4A, AIFF, or WAV.

Let Capo analyze the song for beats, chords, and key information.

Use tempo controls to slow down difficult sections for better listening and practice.

Shift the pitch if you need the song in another key for your instrument or voice.

Loop specific passages to repeat solos, riffs, or vocal phrases until they become comfortable.

Use isolation tools or the spectrogram to focus on individual parts and make your own note or chord corrections.

    Capo 4.6.2 Screenshot 1

What's new in this version:

Capo 4.6.2
Bug Fixes:
- After dragging to adjust the size of a region, Capo once again ensures that the region remains selected. This regression was introduced in the 4.6.1 update, and we regret the error.
- When executing the `resizeRegion()` command from a keyboard or MIDI binding, Capo no longer interrupts the in-progress playback by seeking to the start or end of the region. However, this seek still happens while playback is stopped, so that the new boundary location is reflected in the position display.


Capo 4.6.1
Bug Fixes:
- The mixer popover now appears correctly after pressing the toolbar button.
- When using the previous/next buttons in the Marker, Region, and Chords toolbar items, Capo will now move to the beginning/end of the song after the last item is selected. This matches the behavior of the buttons in the Control Strip on iOS.
- Capo now has improved selection management, where you can no longer have a Region, Marker, and Chord selected at the same time. This problematic state was characterized by three trash cans appearing at once in the toolbar, which is no longer possible.


Capo 4.6
- Capo is now ready for macOS Tahoe, sporting an all-new control layout that feels right at home on your Mac.

New Features:
- Goodbye, Control Strip. Hello, Toolbar:
- We moved all of Capo's controls from the Control Strip to a standard toolbar that looks and feels very familiar on the Mac.
- If you right-click on the toolbar, you can now customize the layout to rearrange controls however you want.
- Each song view has its own toolbar layout, so you can tailor your selections to fit how you work with Capo.

Capo has an all-new icon:
- We were ahead of the curve in 2020 with our glassy icon design, but we tweaked it for macOS Tahoe---it appears more vibrant, and works great with the dark, clear, and tinted icon styles.

Enhancements:
- Under the hood, we cleaned up and modernized our code to work best with the latest OS releases.
- We also improved the scrolling and layout performance, so Capo should feel as glassy and smooth as the new look of macOS!
- If you set a custom colour theme in your System Appearance Settings, Capo now reflects that colour in more places in the UI.
- Improved scroll behavior at the song boundaries - Capo now consistently bounces the whole content area of the Practice and Tabbing song views together as a single unit.

Bug Fixes:
- Capo no longer gets stuck in certain scenarios when you trigger a selectPrevious(.region) command from a MIDI or keyboard binding.
- When Capo is scrolled to the end of the song, playback now runs more smoothly, without the major CPU usage spike that may have impacted audio quality on some machines.
