You should see the waveform of the audio appear: Open up the location where you saved the recording earlier in the file explorer (Windows) or finder (Mac), and drag and drop it onto the Sonic Visualiser window. The next screen you should see is a blank Sonic Visualiser window: Although we won’t be using any network features in this exercise, I’d recommend that you allow network access in case you want to use Sonic Visualiser in the future - it makes installing updates and plugins much easier. The next thing you will see will be a welcome window that requests access to your internet network. You should be presented with the logo splash screen. Open up Sonic Visualiser by locating it in the start menu (Windows) or Applications folder (Mac). ![]() Open the audio spectrogram in Sonic Visaliser. On Windows, you may need to wait a while before pressing ‘Yes’ when the User Account Control screen pops up. dmg (Mac) file you downloaded and follow the installer through to the end to complete the installation. Whatever version you are using, download the program using the primary link.

The Mac version requires OSX 10.12 or later. There seems to be no appreciable CPU hit for leaving the Window Overlap set to its highest setting.The Windows version of Sonic Visualiser runs on most modern updates. The Window Overlap setting blurs or sharpens the blobs.Try it both ways and see what you prefer. You can further focus the fundamentals by changing the normalization on the "Scale" line, but that can also add puddles of blue to other parts of your spectrogram while de-emphasizing the fundamentals. A value of 16384 focuses the fundamentals to a width of only a few Hz while still allowing for reasonably acceptable scrolling motion during playback on my 6th gen Core i3.

The vertical wheel increases and decreases the frequency range on the Y axis, while the horizontal wheel changes the measures per inch, expanding and contracting the X axis. There are zoom controls in the lower right corner of the spectrogram. With an audio file loaded, you'll see the waveform pane and the melodic range spectrogram pane. You can load an audio file through the File menu, through the second toolbar button, or by dragging and dropping a file onto the window.
