Trim_dB is a simple freeware VST2 & VST3 volume trim plug-in. It works by applying the logarithmic decibel system to an audio input from 0 to -96 decibels. There is an LED meter which has an RMS dB output, as well as a mute button.

Trim_dB is a very simple plug-in and works using some of the most basic DSP logic.

The following represents the mathematics of the logarithmic scale, the DSP difference equation in both block and C++ format:

Mathematics:

dB = 20log(x)
x = 10^db/20
where "x" is an input from -96 to 0.

C++:

m_fVolume = pow(10.0, m_fVolume_dB / 20.0);
