What is M4A?

M4A

M4A is MPEG-4 Audio container typically storing AAC or ALAC compressed audio. Part of MP4 family using .m4a extension for audio-only files. Supports metadata tagging, chapter markers, and album artwork. Better quality than MP3 at equivalent bitrates when using AAC codec. Default format for iTunes purchases and Apple Music downloads. Maximum 6GB file size.

  • M4A encodes audio using lossy compression at various bitrates
  • Lossy source limits AIFF quality ceiling—cannot restore removed frequencies
  • Sample rate and bit depth preserved or downsampled for AIFF compatibility

What is AIFF?

AIFF

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format storing PCM waveform data at CD quality (44.1kHz, 16-bit) or higher. Similar to WAV but Mac-native. Large file sizes (10MB per minute at CD quality) but perfect audio fidelity. Converting to other audio formats involves compression decisions.

  • AIFF encodes audio using lossless compression at various bitrates
  • Lossless audio data provides full fidelity for M4A conversion
  • Sample rate and bit depth preserved or downsampled for M4A compatibility
