WAV is an uncompressed, lossless audio file format co-developed by Microsoft and IBM in 1991 based on the Resource Interchange File Format (RIFF) container structure. WAV files store raw, uncompressed pulse-code modulation (PCM) waveform samples, making them the standard reference container for studio recording, music mastering, and broadcast engineering. Because WAV files undergo zero lossy encoding, they preserve 100% of the acoustic frequency spectrum, dynamic range, and stereo imaging. WAV files can be opened effortlessly on Windows via Windows Media Player, macOS and iOS via QuickTime and Apple Music, and in all digital audio workstations (DAWs) including Pro Tools, Ableton Live, Logic Pro, and Audacity.
M4A is an audio-only multimedia container format popularized by Apple in 2001. Built upon the MPEG-4 Part 14 standard, M4A files contain audio streams encoded with lossy Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). Apple adopted the .m4a file extension to differentiate pure audio files from general .mp4 video containers. M4A is the default recording format for iPhone Voice Memos and iTunes purchases. M4A files open seamlessly across all Apple macOS and iOS applications, Windows Media Player on modern Windows, Android media players, VLC, and QuickTime.
