abgate 1.2.0-2build3 (arm64 binary) in ubuntu oracular

 abGate is a LV2 noise gate plugin in the LV2 format to manage
 noise. A noise gate is a component which attenuates an audio
 signal when it falls below a set threshold, so it can be
 applied to an audio track which has one or more periods of
 silence where no noise should be apparent.
