Conversion Settings ShareSets are a powerful method in streamlining audio format settings for a certain type of audio. By changing sample rate, channels, or format you can significantly reduce your memory usage, and with automatic settings you can give a Conversion Settings ShareSet a sort of mindset to estimate proper settings by itself.
