In the previous chapter, we imported audio assets, both music and sound effects, and configured these optimally. As discussed previously, it is most important that music is configured for Streaming as the Load Type, and the Compression Format should be set to Vorbis. This ensures that Unity doesn't load the complete track into memory, which would be performance prohibitive, especially for mobile devices and legacy hardware.

But mixers give you more control over different audio types and their independent volumes and balance (SFX, music, voice, and more).
