Questions about WAV and MP3.
Check the format behavior, limitations, and follow-up options before processing a real file.
WAV stores raw PCM samples — about 10MB per minute of CD-quality stereo — which is ideal for editing but miserable for email, messaging, and storage. MP3 shrinks that dramatically at the Standard setting with little audible difference. Convert the delivery copy to MP3 and keep the WAV as your editing master.
