A variable gain circuit includes: input/output terminals P1 and P2 configured to input/output a high frequency signal; a transistor having a signal terminal a connected to the input/output terminal P1, a signal terminal b connected to the input/output terminal P2, and a control terminal; bias terminals B1, B2 and B3, and a reference voltage terminal respectively set to a first variable voltage, a second variable voltage, a third variable voltage, and a fixed voltage that are independent of one another; an impedance element connected between the bias terminal B1 and the signal terminal a; an impedance element connected between the bias terminal B2 and the signal terminal b; an impedance element connected between the bias terminal B3 and the control terminal; and a first switch configured to switch between connecting and not connecting the reference voltage terminal and the control terminal.

Disclosed is a method of processing an audio recording for facilitating production of competitively loud mastered audio recording with reduced distortion. The method includes receiving an audio file comprising the audio. Further, the method includes providing a first attenuation to the audio recording to produce a first attenuated audio recording and routing the first attenuated audio recording onto an input of a first bus. Further, the method includes providing a second attenuation to the first attenuated audio recording available to generate a second attenuated audio recording and routing the second attenuated audio recording onto an input of a second bus. Further, the method includes providing a third attenuation to the second attenuated audio recording to generate a third attenuated audio recording. Yet further, the method includes processing the third attenuated audio recording to generate a track output. Moreover, the method includes transmitting the track output to the electronic device.

In live music performances it is desirable for a mixing console operator to be able to hear the result of all the processing of a single input signal provided by the various processing steps without the other input signals being present. This is achievable by providing a console (10) which processes an input signal independently of other input signals to produce an operator output signal (210), wherein the processing is arranged to be identical to that applied in combination to the same signal as it is processed, in combination with other signals, for the creation of an output mix (180).

Methods, systems, computer-readable media, and apparatuses for gesture recognition are disclosed for audio control. The gestures can be used for audio control in virtualized environments. The audio control can include generating a sound that mimics an effect of a modification of a sound wave that would occur if the gesture were performed in a non-virtualized environment.
