[Original] using Adobe audition for inner recording

[Indicate the source for reprinting.ArticleIntegrity]

If you want to extract the sound from some videos, inrecord is undoubtedly the best method. Adobe audition (Au) is one of the most powerful audio editing tools. I used it for a while, just to process some basic audio effects, such as trimming and adding effects. I found it quite easy to get started, and it is not worth mentioning because it has powerful functions, today, I want to extract an audio clip from an rmvb video. The first thing I want to think about is to use au for inner recording. After a bit of work, I will get it out and write it down here, to help those confused friends:

First, you need to set an audio record to a recording track:

In multi-track editing mode, click the letter "R" in a sound track to set the sound track to a recording track. At this time, the AU will ask you to save the session and just take a picture.

Next, double-click the volume icon (speaker) at your system tray, select "option" → properties, select "Recording" in the "Adjust volume" group, and click "OK ":

In the displayed dialog box, select the stereo mix item:

Now you can go back to AU. In this case, you need to open the video file you want to extract a piece of audio and play the one you want to extract, click the AU recording icon to start recording (red icon ):

The following work should not be said. After the recording is completed, the audio can be processed subsequently.
