MP3 vs WAV
Which audio format should you choose?
MP3 wins on universal support on every platform. WAV wins on lossless, studio-grade quality. For most general use, pick whichever is more compatible with your existing tools — file size and quality differences are usually small at the same encoding settings.
When to use MP3
Choose MP3 when you need music playback on every device or podcast distribution. Its strengths: universal support on every platform, and very small file sizes.
Pros
