Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Visualised Audio
This app analyzes single musical notes, displaying their pitch and visualizing harmonics. It helps musicians refine their playing technique by showing accuracy to pitch and the subtle differences in instrument sound through harmonic analysis. It requires microphone access and a quiet environment for optimal performance.
- Monophonic pitch detection
- Note and harmonic visualization
- Playing technique fine-tuning
- Harmonic analysis of instruments
- Practice aid for scales
- Adjustable sensitivity slider

Visualised Audio can classify single notes using monophonic pitch detection and visualise notes and harmonies. Visualised Audio can help you fine tune your playing technique by showing you how close to pitch you are. Visualised Audio can show you all the beautiful harmonics that your instrument is creating. Is there a difference between your $100 instrument and your $2000 instrument? Visualised Audio is a fun tool to use while you're practising scales as it's showing you what the notes look like and which harmonics lie on top of the fundamental pitch. If your instrument is creating strong harmonics you can use the slider at the bottom make the application less sensitive and thus help it classify the fundamental pitch instead of the harmonic. Left on the slider means less sensitive to harmonics. The default value should be good for most people. Since the application makes heavy use of the microphone it needs both access to it as well as a relatively quiet environment. Note - The classified note detected by the app Error - The deviation from the note in cents Clarity - How pure the signal is. This has nothing to do with error.

Verdict
The clearest difference is in-app purchases: CA PRO DSP at none against Visualised Audio's 3. CA PRO DSP also leads on update cadence (every 2 months vs every 14 months) and iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
