About MP4 and WAV
MP4: MP4 is the universal video format. With H.264 video and AAC audio it plays on every iPhone, Android phone, smart TV, browser, WhatsApp, Instagram and YouTube.
WAV: WAV stores uncompressed PCM audio, so it keeps every bit of the original sound. Files are large, but WAV is the standard for audio editing, studios and professional software.
