+
+This extension contributes the following settings:
+
+* `spectrogram.rgbColor`: Set color for rendering spectrogram
+* `spectrogram.showDuration`: Show duration in treeview/file explorer. Disabling it would load file items faster if the directory has many audio files
+
+## Known Issues
+
+Autoplay policy prevents starting the song from selecting the audio file in the treeview.
