about these formats
AIFF
AIFF is an uncompressed audio format developed by Apple. Like WAV, it preserves full audio quality but produces large files. AIFF is common in professional audio production on macOS.
M4A
M4A is an audio container used by Apple's iTunes and QuickTime. It typically uses AAC compression for better quality than MP3 at the same bitrate. M4A is common in podcasts and Apple Music downloads.
