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.

WVE is the audio format native to the Psion Series 3 family of personal digital assistants, released by British company Psion PLC beginning in September 1991. These clamshell PDAs included a built-in voice recorder, and all dictation functionality relied on WVE files to store captured sound. Each file begins with the ASCII signature "ALawSoundFile**" followed by a minimal header, then raw A-law encoded audio sampled at 8 kHz — a rate inherited from digital telephony standards. At 8000 bytes per second, a one-minute recording occupies just 480 KB, which was essential given that Psion devices stored data on SRAM cards typically ranging from 128 KB to 2 MB. The A-law encoding provides reasonable speech clarity within these tight storage constraints, prioritizing intelligibility over high-fidelity reproduction. WVE files can be converted to WAV or other modern formats using SoX, Awave Studio, or specialized Psion file utilities. While the format is firmly a product of early-1990s handheld computing, it holds historical significance as one of the first audio recording formats designed for pocket-sized consumer devices. Collectors and researchers studying mobile computing history occasionally encounter WVE files when recovering data from legacy SRAM media.
