Ambience

Inspired by the element of air, it resonates with the environment. Ambience is an input module that can amplify sound to the module level through its built-in mic, an external mic, or line input. It generates envelope follower signals, gate signals, and pulse signals from the input, and all signals are adjustable.

 
The built-in microphone picks up ambient sounds, which are amplified through sound gain and output as module-level audio at the sound output. The mic jack is powered and can accept polarized microphones that require power, as well as line or module audio. When module audio is inserted, the optional gain knob may cause clipping and overdrive effects on the signal. After a signal line is inserted into the mic jack, the built-in microphone is isolated. The sound output is internally connected to the envelope processing section. When there is an external signal input in the envelope processing section, the internal connection of the sound is disconnected.

​

The envelope processing section generates an envelope following signal from the input audio, which is output at the envelope output. The decay, threshold, and gain of the envelope following signal are adjustable. When the voltage of the envelope following signal is higher than the set threshold, a high voltage signal is output at the gate; otherwise, 0 is output. The threshold can be set through the gate verf. Note that setting the threshold too low will result in a continuous high level at the gate output, and setting it too high may result in a continuous 0 output. When the gate output rises from a low level to a high level, a pulse signal is output at the trigger port.
