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.[1]
Audio Units allows sound file audio time stretching and pitch scaling (e.g., timestretch), sample rate conversion, and streaming over a local area network. It also comes with a set of AU plug-ins such as EQ filters, dynamic processors, delay, reverb, and a Soundbank Synthesizer Instrument.
AU are used by Apple applications such as GarageBand, Logic Pro, Final Cut Pro, MainStage, Soundtrack Pro (discontinued), and most 3rd party audio software developed for macOS such as Ableton Live, Amadeus Pro, Ardour, Audio Hijack, DaVinci Resolve, Digital Performer, Gig Performer, REAPER, and Studio One.

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.
B-Step Sequencer is a multitrack software MIDI step sequencer that is available as either a standalone application or in audio plug-in format (VST and Audio Units). Primarily used to create melodical sequences to trigger soft or hardware synthesizer, whether in a studio environment or live on stage, it has a user interface based on pattern and TR music sequencers.
Audio equipment refers to devices that reproduce, record, or process sound. This includes microphones, radio receivers, AV receivers, CD players, tape recorders, amplifiers, mixing consoles, effects units, headphones, and speakers. Audio equipment is widely used in many different scenarios, such as concerts, bars, meeting rooms and the home where there is a need to reproduce, record and enhance sound volume. Electronic circuits considered a part of audio electronics may also be designed to achieve certain signal processing operations, in order to make particular alterations to the signal while it is in the electrical form. Audio signals can be created synthetically through the generation of electric signals from electronic devices. Audio electronics were traditionally designed with analog electric circuit techniques until advances in digital technologies were developed. Moreover, digital signals are able to be manipulated by computer software much the same way audio electronic devices would, due to their compatible digital nature. Both analog and digital design formats are still used today, and the use of one or the other largely depends on the application.
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.
