Hi, Dexster allows to mix audio from memory or from another audio file. To use the mixing feature, load one of the audio file. Once loaded, make selection of the waveform area to be mixed, click on Edit Menu -> Mix from File and select the second audio file. You may also select Mix if you have copied any audio into the memory. Please let me know if you need further assistance. Thank you
Best Regards;
