M4A vs WAV
Een uitgebreide vergelijking van M4A Audio en WAV Audio — bestandsgrootte, kwaliteit, compatibiliteit en welk formaat het beste past bij jouw workflow.
M4A Audio
Audio FilesM4A is an MPEG-4 audio container typically containing AAC or ALAC encoded audio. It is the standard format for iTunes purchases and Apple Music downloads.
Over M4A-bestandenWAV Audio
Audio FilesWAV is an uncompressed audio format that preserves full audio fidelity. Files are large but provide lossless, CD-quality sound. It is the standard working format in audio production and editing.
Over WAV-bestandenVergelijking van sterke punten
M4A Sterke punten
- Superior audio quality to MP3 at the same bitrate (AAC codec).
- Native support across Apple, iOS, Android, and Windows.
- Carries rich metadata: album art, chapters, lyrics, podcast bookmarks.
- Same container as MP4 — tooling overlaps with video workflows.
- Lossless variant (ALAC inside M4A) for audiophile archiving.
WAV Sterke punten
- Bit-perfect, uncompressed audio — the professional studio standard.
- Universally supported for playback, editing, and analysis.
- No re-encoding penalty — edit and save repeatedly with zero quality loss.
- Simple internal structure — easy to parse programmatically.
- Supports up to 32-bit float and 384 kHz sample rates.
Beperkingen
M4A Beperkingen
- AAC patents still active in some jurisdictions — licensing fees apply for encoders.
- Seeking in variable-bitrate M4As can drift without an index atom.
- Less universal than MP3 on older hardware (pre-2010 car stereos, cheap MP3 players).
- Container overhead is larger than a raw ADTS AAC stream.
WAV Beperkingen
- Enormous file sizes — 10 MB per minute for CD-quality stereo.
- 4 GB size limit for standard WAV (RF64/W64 variants extend it but break compatibility).
- No native support for cover art or rich metadata.
- Impractical for casual listening or bandwidth-constrained delivery.
