WAV — Waveform Audio File Format
| File extension | .wav .wave |
|---|---|
| File category | audio |

| MIME type | audio/wav audio/x-wav |
| Developer | Microsoft, IBM |
WAV (Waveform Audio File Format) is an uncompressed audio container developed by Microsoft and IBM, introduced with Windows 3.1 in 1991. WAV stores raw PCM audio data — typically 16-bit or 24-bit samples at 44.1 kHz or 48 kHz — making it the standard format for professional audio editing, broadcast production, and sound archiving. Because WAV is uncompressed, files are large (approximately 10 MB per minute at CD quality), but no encoding artifacts are introduced, ensuring pristine audio fidelity. WAV is natively supported by Windows, macOS, and virtually all digital audio workstations including Audacity, Adobe Audition, and Logic Pro.

M4A — MPEG-4 Audio File
| File extension | .m4a |
|---|---|
| File category | audio |
| Programs | Apple iTunes VLC media player Windows Media Player foobar2000 Winamp |
| Tech description | https://en.wikipedia.org/wiki/M4A |
| MIME type | audio/mp4 audio/x-m4a |
| Developer | Apple Inc. |
M4A is an audio-only file container based on the MPEG-4 standard, introduced by Apple in 2004. The .m4a extension distinguishes audio-only files from .mp4 files that contain video. M4A files are most commonly encoded with the AAC codec, offering better audio quality than MP3 at the same file size. Lossless encoding using Apple Lossless (ALAC) is also possible within the M4A container. M4A is the default format for music purchased from the iTunes Store and Apple Music. It is natively supported on all Apple devices, and plays on Android, Windows, macOS, VLC, foobar2000, and Windows Media Player.
