Take audio from YouTube
From SoundTaxi
With SoundTaxi you have a great opportunity not only to download any video, also you can extract any audio from YouTube videos. All you need to do is to follow a few simple steps.
First of all, please open SoundTaxi settings, find "Encoder for video files" and select AAC – MPEG4 Audio or MP3 – MPEG Layer-3 Audio as output format from the drop-down list.
Also you can select a desired “Compression Quality” for MP3 and M4A files from the drop-down list. The highest compression quality is 320 kbps, but if you need to reduce the size of converted files – 170 kbps is the optimal value.
Close the settings by clicking "OK".
Open YouTube video in Internet Explorer, then select "Tools -> Rip YouTube file embedded in this page" from the menu.
The audio will be taken from Youtube automatically and converted by SoundTaxi.
Note, you need SoundTaxi Pro+VideoRip edition to take audio from YouTube videos.
