AG Audio Watermark Generator for Mac

AG Watermark Generator allows you to add several audio files to serve as watermark and play successively with the original track. You may choose the offset for the watermark, as well as the repetition interval. When configuring the output file, you may choose to apply the watermark to each file in the list, then save them as individual songs or to merge the output files. Moreover, you may adjust the audio quality, output folder and a prefix/suffix for automatically renaming the results.
