Decibel Mixer

Functional Description
Single- or dual-input audio amplifier/router/mixer with adjustable channel gains specified in decibels (dB). Each channel can be independently muted or inverted (i.e. have its sign reversed).

NOTE: A gain specified in dB, denoted GdB, corresponds to the linear gain (i.e. the amplitude multiplication factor), denoted G, according to the formula: G dB = 20 log10 G. The logarithmic gain is most commonly used in audio since the human hearing response is logarithmic (in terms of perceived amplitude differences).

Algorithm
Signals are amplified (by muliplication by the appropriate linear gain factors), summed, and routed, using floating-point arithmetic throughout.
Signal Implementations
Audio signals Control signals Description
Single input single output mono-mono n/a Mono output obtained from the single mono input multiplied by the single gain (no mixing, just amplification)
Single input single output mono-stereo n/a Stereo output obtained from the single mono input multiplied by two separate gains (no mixing, just amplification and routing)
Single input single output stereo-mono n/a Mono output obtained by summing the channels of the single stereo input after multiplying each by a separate gain
Single input single output stereo-stereo n/a Stereo output obtained from the single stereo input multiplied by a separate gain for each channel (no mixing, just amplification and routing)
Double input single output mono-mono n/a Mono output obtained by summing the double mono inputs, after multiplying each by a separate gain
Double input single output mono-stereo n/a Stereo output obtained by multiplying the double mono inputs by a separate gain, then routing them to the left and right output channels, respectively (no mixing, just amplification and routing)
Double input single output stereo-mono n/a Mono output obtained by summing all four channels corresponding to the double stereo inputs, after multiplying each by a separate gain.
Double input single output stereo-stereo n/a Left channel output obtained by summing the left channels of the double inputs, after multiplying each by a separate gain. Right channel output obtained by summing the right channels of the double inputs, after multiplying each by a separate gain.
