Controlling Drum Bleed with Laser Vibrometry

Document Thumbnail

Using multiple microphones to capture the sound of multiple drums on a drum kit is common practice. As well, the bleed captured by such a setup is a common problem for sound engineers. Gating is often used in an attempt to manage drum and instrument bleed into individual drum channels. However, the overlap in amplitude and frequency content of different drums makes gating based solely on the microphone audio difficult and unwanted triggering of the gate is a common problem. By measuring the physical vibration of the drum head using simple laser vibrometry and using this signal to run the sidechain of a gate, the dynamic range of the gate’s signal follower is increased and false triggering is easier to avoid. This allows for more precise control over each drum channel’s tone and dynamics
