Abstract
Described herein are audio capture systems and methods. One embodiment provides an audio capture system (1) including: microphones (9-11) positioned to capture respective audio signals from different directions or locations within an audio environment; a mixing module (7) configured to mix the audio signals in accordance with a mixing control signal to produce an output audio mix, wherein, upon the detection of vibration activity, the mixing control signal controls the mixing module (7) to selectively temporarily modify one or more of the audio signals to reduce the presence of noise associated with vibration activity in the output audio mix.
