MixAudio

In general, the program meets my expectations. I was able to achieve the desired results with its help, using links to music files on YouTube in addition to hints.
What I miss: chat for contacting support, because sometimes there are unclear errors. The ability to delete unsuccessful variants from the generated 4 variants, leaving only the favorite one (usually one in each four). Possibilities to create a catalog for music with custom headings. Now they are sorted into three categories: all created, liked and downloaded. But even without this, the program deserves the highest rating, if you are satisfied with the global license for non-exclusive use of the created music
