Step 1: After free downloading the software, double-click the file to open the installer and start the installation. In this step, you should accept the license agreement and click the Install button.
Step 2: Open your web browser and access the YouTube music you want to record, and then run the software. The smart program will automatically detect the music as you like.

Step 3: Now hit record without leaving the page. Once you hit record, the Audio Recorder is on standby and will automatically begin recording as soon as you press play in the browser. You can just press play in the browser and your job is done.
Tips: While recording, don’t worry about leaving the stream page. This will not affect your recording in any way. Free to open and surf on other tabs or windows, or even open a new browser.
The smart program will help you rip music from YouTube videos with the simple 3 steps. To view and test your newly recorded track, open the Audio Recorder main tray (that window that opened when you started the program). You will find the output quality as good as the original source.
How wonderful it is! Just free download it and copy music from YouTube videos by yourself!
