Live inspection
A compact audio instrument that stays beside the page.
The extension is designed for quick checks while a reference track, video, stream, or other audible webpage continues playing.
Scrolling spectrogram
Follow changes in frequency energy over time without opening a DAW or uploading the source audio.
Useful controls
Adjust FFT size and smoothing, freeze the display, hold peaks, and reset the peak trace.
Three steps
Start with the tab you are already listening to.
- Open audible media
Visit a normal Chrome webpage and start playing its audio.
- Open the extension
Select the toolbar icon to grant temporary access and open the side panel.
- Start capture
