If for some reason you need to record sound from the Google Chrome tab, then in this post you will find a solution.
Chrome Audio Capture helps you record sound from the Chrome tab.
After installing the extension, you can immediately start recording. Open the tab you want to record, click the Chrome Audio Capture icon and click the Start Capture button.
At the end of the recording, click Save Capture. Recording can be started and stopped using hot keys. You cannot close the tab before saving the audio, otherwise the file will be lost.
If desired, in the settings you can change the quality and format of the audio. Additionally, you can disable the recording limit of 20 minutes, but the developer does not recommend this. The limit is due to the memory limit available for Chrome.
