WhatAmIHearing
An open-source Shazam client for identifying music on your PC. For when your phone’s microphone just doesn’t cut it.
How do I get it?
Direct Download
Go to the Releases Page and on each release there is a zip file attached named WhatAmIHearing.zip:
Click it to download the zip file, unzip it, and run WhatAmIHearing.exe to open the app.
WinGet
WhatAmIHearing is available to install via WinGet with the following command:
winget install zemoto.WhatAmIHearing
By default, it will install to %LOCALAPPDATA%\Microsoft\WinGet\Packages and a WhatAmIHearing command will be added to your command line to launch the app from there.
Updating
Settings and history are stored in config.json next to WhatAmIHearing.exe by default. As of v3.5, there is an option under “Window Settings” to instead save it in AppData. When updating, if not saving to AppData, you need to move config.json from your previous version and put it next to the new WhatAmIHearing.exe.
Rate Limiting
Shazam’s API has a monthly quota of 500 requests per month on the free tier. To work around this the app supports using your own API key instead of the one bundled with the app.
To get an API key:
- Go to https://rapidapi.com and make an account.
- Go to https://rapidapi.com/apidojo/api/shazam and subscribe to the free tier. This should not require any additional info.
- Go to https://rapidapi.com/developer/dashboard to see a new Shazam app created for you.
- The Authorization section of that app contains the API key which can be pasted in the API Key text box in the app. WhatAmIHearing will immediately start using the new key without having to restart.
Feel free to ask any questions or report any issues by creating a new Issue.
Technical Details
Written in C# with WPF for the UI.
ZemotoCommon is my utility submodule containing classes that I use in all of my projects.
Uses POST calls to Shazam’s API with the raw audio in the body for song detection. API calls are defined in the Api class. HTTP calls are made via the built-in HttpClient class and handled in the ApiClient wrapper class.
The NAudio package is used for recording, resampling, and playback. The Recorder class handles wrapping all the recording logic.
Compiling
The app is compiled with Visual Studio Community 2026. The default API key commited to GitHub is a placeholder. If you compile the app yourself it will not work without your own API key.
For building the release version, I use the Publish feature in Visual Studio with the following settings:
- Configuration:
Release (default configuration provided by Visual Studio)
- Target Framework:
net10.0-windows7.0
- Target Runtime:
win-x64
- Deployment Mode:
Framework-dependant or Self-contained depending on the version I am building.
