What Are AU Plugins?
AU or Audio Unit is an audio plug-in format developed for macOS and iOS. In many ways, it can be considered the Mac equivalent of VST plug-ins. Like VSTs, AU plug-ins span the range from software instruments to effects units. They may generate sounds, as in the case of software synthesizers, or they may process audio, as in the case of reverb or delay plug-ins. Whether used to generate sounds or to process them, AU plug-ins are capable of low-latency performance, with practically real-time output.
