About M4A to AIFF Conversion
Converting M4A to AIFF decodes the compressed audio (AAC or ALAC) inside the M4A container and writes it as uncompressed PCM in Apple's AIFF format. AIFF stores raw audio samples in big-endian byte order with no compression, making it the standard working format for macOS audio production. This conversion is essential when importing iTunes or Apple Music files into professional DAWs that require uncompressed input for editing, processing, or mastering.
Why Convert M4A to AIFF?
Professional audio workflows in Logic Pro, Pro Tools, and Ableton Live on macOS often prefer AIFF as the working format because uncompressed PCM avoids any CPU overhead from real-time decoding during playback and recording. AIFF is also required for some CD mastering software, broadcast audio delivery, and archival standards that mandate uncompressed format. If you have an M4A library and need to bring tracks into a production environment, AIFF is the standard target.
Common Use Cases
- Importing Apple Music or iTunes purchases into Logic Pro for remix or mashup production
- Preparing voice memo M4A recordings for professional editing in Pro Tools
- Delivering uncompressed audio masters to a recording studio that works exclusively with AIFF
