Cool application! I never heard of it. I will use it at a disco or a concert by my favorite singer. I found some apps on https://www.movavi.com/screen-recorder-mac/ that work exclusively to record video, webinars, calls. I think the QuickTime player is used to recording music, but I wouldn't say I like its slow functionality, low-quality sound recording, and large file size. I hope this one is a lot better. I am too excited to try it on my Mac, even if I had an old laptop version. Thanks one more time for sharing.
