About formats

M4R is the designated ringtone format for Apple iPhone devices, introduced alongside the original iPhone in 2007. Technically, an M4R file is an AAC-encoded MPEG-4 audio container identical in structure to M4A — the only meaningful differences are the file extension and a duration constraint of roughly 30-40 seconds enforced by iOS. Apple chose this approach so existing AAC encoder infrastructure could produce ringtones without codec-level modifications, while the distinct extension prevents regular music tracks from appearing in the ringtone picker and vice versa. Creating an M4R involves encoding a short audio clip as AAC, trimming it to the allowed length, and renaming the file. iTunes (or Apple Music on recent macOS) and GarageBand both provide built-in workflows, and third-party tools like Audacity handle it equally well. Once synced or downloaded, the ringtone integrates with iOS settings for calls, alarms, and per-contact alerts. Practical advantages include effortless deployment to any iPhone through iTunes sync or AirDrop, high-quality playback from the AAC codec even at small file sizes, and the ability to assign individual ringtones to specific contacts for instant caller identification.

MAUD is an audio file format developed by MacroSystem for the Commodore Amiga platform, introduced in the early 1990s as part of their digital video and audio production tools. Built on the Amiga IFF (Interchange File Format) chunk architecture, MAUD files organize data into clearly delineated chunks — MHDR for the header, MDAT for sample data, and optional annotation chunks for metadata. The format supports mono and stereo layouts with bit depths of 8 or 16 bits and sample rates up to 48 kHz, which represented professional-grade specifications on Amiga hardware. Both signed linear PCM and A-law/mu-law encodings are available, offering a choice between fidelity and file size. MAUD saw primary use in the Amiga video production community, where MacroSystem Retina and VLab Motion boards demanded synchronized audio that the standard 8SVX format could not deliver. Conversion support exists today through SoX and libsndfile, ensuring vintage Amiga productions remain recoverable. Three distinct advantages stand out: clean IFF-based structure that any chunk-aware parser can navigate, 16-bit stereo capability ahead of typical Amiga audio, and lightweight overhead that left maximum CPU headroom for video rendering.
