The Core Audio Format is a container format for storing audio, developed by Apple Inc. It is compatible with Mac OS X 10.4 and higher; Mac OS X 10.3 needs QuickTime 7 to be installed.[1]
Core Audio Format is designed to overcome limitations of older digital audio formats, including AIFF and WAV. Just like the QuickTime .mov container, a .caf container can contain many different audio formats, metadata tracks, and much more data. Like the RF64, it is not limited to a 4 GB file size and a single .caf file can theoretically save hundreds of years of recorded audio due to its use of 64-bit file offsets.[2]
GarageBand, Soundtrack Pro, and Logic Studio use the .caf format for their loop and sound effects library, particularly for surround-sound audio compressed with the Apple Lossless (ALAC) codec. It is also what is used to send Audio Messages over iMessage on iOS and macOS.

DTS-HD Master Audio (DTS-HD MA; known as DTS++ before 2004) is a multi-channel, lossless audio codec developed by DTS as an extension of the lossy DTS Coherent Acoustics codec (DTS CA; usually itself referred to as just DTS). Rather than being an entirely new coding mechanism, DTS-HD MA encodes an audio master in lossy DTS first, then stores a concurrent stream of supplementary data representing whatever the DTS encoder discarded. This gives DTS-HD MA a lossy "core" able to be played back by devices that cannot decode the more complex lossless audio. DTS-HD MA's primary application is audio storage and playback for Blu-ray media; it competes in this respect with Dolby TrueHD, another lossless surround format.
CLever Audio Plug-in or CLAP is an open source software architecture, application programming interface and reference implementation suite for audio effect plugins as used in multimedia software such as digital audio workstations, audio editing software, and video editing software with integrated audio workflows. The specification and reference implementation was released in 2022 by the Berlin-based audio software companies u-he and Bitwig. CLAP was created as an open licensed alternative to proprietary audio plugin formats such as Steinberg's VST format, Apple's Audio Units format, or Avid Technology's Avid Audio Extension (AAX) format, designed for non-destructive parameter automation, multi-voice envelopes, true MIDI 2.0 support, better multi-core CPU performance and greater ease writing plugins in a non-proprietary licensing framework under the MIT License. CLAP is supported by 15 DAWs and 93 plugin producers who have produced 394 CLAP plugins.
Audio Units (AU) are a system-level plug-in architecture provided by Core Audio in Apple's macOS and iOS operating systems. Audio Units are a set of application programming interface (API) services provided by the operating system to generate, process, receive, or otherwise manipulate streams of audio in near-real-time with minimal latency. It may be thought of as Apple's architectural equivalent to another popular plug-in format, Steinberg's Virtual Studio Technology (VST). Because of the many similarities between Audio Units and VST, several commercial and free wrapping technologies are available (e.g. Symbiosis and FXpansion VST-AU Adapter). Celemony Software and PreSonus have also developed the Audio Random Access (ARA) extension, which works with both AU and VST, allowing greater integration between the plug-ins and DAW software.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
