Opus, associated with Opus Audio, is an open, royalty-free audio codec designed for high-quality voice and music streaming. Introduced by the Internet Engineering Task Force (IETF) in 2012, it adapts seamlessly to various applications like VoIP, videoconferencing, in-game chat, and live music performances. Known for its versatility, low latency, and high compression efficiency, Opus is widely adopted in modern communication platforms and web applications, making it a cornerstone in contemporary audio technology.
The M4R file extension stands for MPEG-4 Ringtone and is primarily used for creating custom ringtones for Apple devices, particularly iPhones. This format, a variant of the standard MPEG-4 Audio (M4A), emerged alongside the introduction of the iPhone in 2007. M4R files utilize Advanced Audio Coding (AAC) for compression, ensuring high-quality sound in a compact file size. Their use is strictly tied to Apple's ecosystem, allowing users to personalize their device's ringtones through the iTunes platform. M4R's history is closely linked to the evolution of mobile technology and the personalization trend in smartphone usage.
