Hi, About docs https://www.dtdevtools.com/docs/masteraudio/AudioMemoryAllocations.htm mp3 file take 2.4ms wav file take 0.02 seconds I think 2.4ms < 0.02 seconds. And see That's 120 times faster! Don't know it was a typo? 0.02 seconds should be revised to 0.02ms? According to document sound effects use .wav files ? How about compression Format to be use on android and iOS?
