|🔸 Description||Opus is a lossy audio coding format developed by Xiph and standardized by the IETF, designed to efficiently code speech and general audio in a single format while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end ARM3 processors.||MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio. However, it can also be used to store other data such as subtitles and still images. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files.|
|🔸 Technical details||Opus supports constant and variable bitrate encoding from 6 kbit/s to 510 kbit/s, frame sizes from 2.5 ms to 60 ms, and five sampling rates from 8 kHz (with 4 kHz bandwidth) to 48 kHz (with 20 kHz bandwidth, the human hearing range). In addition, an Opus stream can support up to 255 audio channels, and it allows channel coupling between channels in groups of two using mid-side coding.||Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of non-protected content. M4A is often compressed using AAC encoding (lossy) but can also be in Apple Lossless format.|
