Abbrev Shorthand for Explanation
AB Audiobus An IOS software that allows to connect audio and midi application. Currently using the IAA protocoll for inter process communication. The AB app supports AU plugins and offers application switching and application state saving and remote control (see Audiobus features)
AB3 Audiobus 3 Third version of the AudioBus protocoll
ABF Audiobus Forum The main forum for IOS musicians and developers
AD Audio Damage A company offering audio plugins
AD Attack Decay A synthesizer envelop module with attack and decay parameter
ADSR Attack Decay Sustain Release A synthesizer envelop module with standard parameters, mainly used to shape the sounds amplitude with a VCA or the overtone amount with a VCF
AM Amplitude Modulation Sound synthesis: Modulating the volume of an audio signal with another audio signal (Wikipedia)
AP Auria PRO An audio and MIDI workstation app
ARP Arpeggio A synthesizer module that breaks chords into a sequence of notes
AT Aftertouch A midi message allowing to add additional pressure information to notes (per midi channel). The AT midi message affects all currently playing notes - there is a Poly Pressure midi message to allow per note pressure information
AU Audio Unit Apples audio plugin format for Audio and Midi plugins, currently version 3 (AUv3)
AU Host Audio Unit Host An application that can load plugins in the AUv3 format
AUM Audio Mixer An audio mixing app (like Audiobus) with support for user defined channel routing, supports IAAs and AUv3. AUM itself can be loaded in Audiobus to achieve state saving and process switching for IAAs
AUv3 Audio Unit Version 3 Apples audio plugin format for Audio and Midi plugins, there are several plugin subtypes types depending on the inputs and outputs of the plugin (see AU features, or for list of AUs and hosts)
BM3 Beat Maker 3 An audio and MIDI workstation app
CC Control Change A group of 119 midi message for parameter changes, sometimes also named continuous controller
CCK Camera Connection Kit A dongle to connect USB devices like audio or midi interfaces to the lightning port
CPP Chord Poly Pad A MIDI chords player app with AB3 state-saving support
CV Control Voltage Analog modular synthesizers use voltages to modulate the sound generation - mainly 1 volt/octave in Eurorack Modular Synth. The counterpart in the digital world are midi CC send between plugins. (see Wikipedia)
DAW Digital Audio Workstation A software used for recording, editing and producing audio files. (see Wikipedia)
EG Envelop Generator A synthesizer module generating a control voltage that varies over time. The start of the envelop is triggered by either a trigger pulse or a gate signal (see Wikipedia). There are different types of envelops like AD, ADSR
ENV Envelop Generator See EG
EQ Equalizer A plugin or app adjusting the balance between frequency components (Wikipedia)
FF FabFilter A company offering audio plugins
FM Frequency Modulation Sound synthesis: Modulating the frequency of an audio signal with another audio signal generates interesting (often inharmonic) overtones (Wikipedia)
GB Garage Band Apples free audio and MIDI workstation app
GUI Graphical User Interface A user interface that allows interaction through the use of graphical icons and visual indicators (see Wikipedia)
IAA Inter-App-Audio An Apple audio / midi protocoll to connect stand-alone, fullscreen applications (see IAA features)
LFO Low frequency Oscillator A synthesizer module that generates cyclic control voltages with a frequency below 20 Hz (see Wikipedia)
MIDI Musical Instrument Digital Interface A technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing and recording music. Each midi connection supports 16 channels to unidirectional transmit information. There are 8 types of messages. (See Wikipedia)
MOD Modulation Midi CCs and analog CV signals can be used to vary/modulate sound generation parameters
MPE MIDI Polyphonic Expression Part of the latest midi standard. It defines how to apply per note pitch bend and other controllers. Basically each each note gets its own midi channel and all information on that channel are related to just that note. The midi channel 1 (or 16) is reserved for control messages - two MPE instruments may share a 16 channel midi connection
NS2 Nano Studio 2 An app for IOS music production
OSC Oscillator A synthesizer module for generating audio signals. Audible signals are mainly generated by VCOs, control signals by LFOs
PB Pitch Bend A midi message to specify pitch bending - the value is applied to all playing notes of the midi channel
PC Program Change A midi message to change instrument patches (per midi channel)
PP Poly Pressure A midi message specifying per note pressure information (per midi channel)
RM Ring Modulator A synthesizer module applying multiplication between audio signals resulting in inharmonic overtones
SB Sugar Bytes A company offering audio plugins
SEQ Sequencer A synthesizer module that sends out notes and control voltages in discrete steps. The sequencer itself can be triggered with a clock of lfo signal
S&H Sample & Hold A synthesizer module that takes a sample from an input signal and holds this value until the next control pulse (see Wikipedia)
UI User Interface The user interface is the space where interactions between humans and machines occur (see Wikipedia)
UXD User Experience Design User experience design (UXD, UED, or XD) is the process of enhancing user satisfaction with a product by improving the usability, accessibility, and desirability provided in the interaction with a product (See Wikipedia)
VCA Voltage Controlled Amplifier A synthesizer module controlling the audio volume using control voltages. Most common modulator is an envelop generator to shape the sound
VCF Voltage Controlled Filter A synthesizer module for filtering audio signals where the cutoff frequency is controlled by a control voltage
VCO Voltage Controlled Oscillator A synthesizer module for generating audio signals where the frequency is controlled by a control volage. Often additional sound generation parameters like pulse width, slope or waveform can be controlled by other control voltages (see Wikipedia)
