Small series first to introduce the concept of stereo mixing. As a simple example: computer generally has three channels, left channel (left horn), right channel (right speaker), stereo channel, audio and video files may sound will be due to a different sound, and stereo channel is about two channels together audible, for example, in the play MP3 file, Play background music on one side and play the voice on the other. The premise of using stereo mixer is that sound card needs to support mixing function. If the computer does not support mixing, the audio device will be affected. Small series to introduce XP system sound card does not support the blending function of the solution.
The method is as follows:
1, the mouse clicks the XP system "starts" the menu, chooses "runs" the option;
2, in the Open Operation dialog box, enter the "REGEDIT" character command, press OK key;
3. In the Open Registry Editor, expand to the left:
HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, control, Class, {4d36e96c-e325-11ce-bfc1-08002be10318},
0005, settings, filter, rear options;
4, in the same folder under the new two binary values: named "Digitalinputmonitor", "Digitalstereomix";
5, two key value of the data are set to 1;
6, shut down the Registry Editor, restart the computer, this time "volume control" in an extra item "input Monitor";
7, recording control of a more than one option "stereo mixing", when the recording selected to "Stereo mixing" can realize the mixing function!
Although the XP system sound card does not support the mixing function is very troublesome, but uses the above method to make the difficulty easy. I hope this method can help you, and I hope you can try to use this method.
