You can use audio editing software to convert to stereo music. I used GoldWave to convert it. Many audio editing software can be used, such as: Audition1.5 Samplitude 8.0, etc... 1. First open GoldWave the main interface, and then click [Open] under [File] for the mp3 music you want to convert. 2. After the music is opened, click [New] under [File] to pop up the new sound dialog box. Adjust the sampling rate to 44100HZ and the length to the length of your music and then confirm. 3. Click on the mp3 music you opened, then click [Edit] [Copy], then click New Sound, click [Left Channel] under [Channel] under [Edit], and then click [[Left Channel] under [Edit] Paste] At this time, your mp3 music will be pasted to the left channel track of the new music. 4. Also click [Right Channel] under [Channel] under [Edit] and then click [Paste] under [Edit]. Then your mp3 music will be pasted to the right channel track of the new music. superior. 5. Click [Both] under [Channel] under [Edit], then mark the music part of the music track black and click [Delete] under [Edit] to delete the excess length. 6. Click the play button on the device controller to listen to your stereo music.

7. Turn off your original mono track, click [Save As] under [File] to pop up the Save As dialog box, find the drive letter you saved under Save In, change the file name to your music name, and select the save type. The type you need is such as: mp3, wav, etc..., then click save and it's OK! /soft/5236.htm Software link download address
