MP3 vs WAV
MP3 · MPEG-1 Audio Layer III
MP3 is the universal lossy audio format — it plays on practically every device, app and car stereo ever made. Files are small and quality at 192kbps+ is transparent for most listening.
WAV · Waveform Audio
WAV stores uncompressed, lossless PCM audio. It's the studio-grade choice for editing and mastering, but files are large (about 10MB per minute of stereo CD-quality audio).
