WAV vs AAC
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).
AAC · Advanced Audio Coding
AAC is the lossy codec inside most .m4a files and streaming audio. It sounds better than MP3 at the same bitrate, but isn't as universally playable on older or non-Apple hardware.
