Use this option to join several audio files, regions or several copies of the same file. Batch Join can be used to join both files open in WavePad and outside files. The order of the joining files can be handled through drag and drop. In the joining process the maximum channel count and the sample rate are taken from the selected files. For example, if we join one mono and one stereo file, the merged file will be a stereo file. If we join two files with sample rate 44100 and 64000, then the merged file will have the sample rate of 64000. After the join process the merged file is opened in WavePad.
