A flexible 3-input audio mixer that blends its inputs into a single mono or stereo output. Every input has its own linear Gain fader (default 1/3, about 0.3333, so the inputs sum to roughly unity out of the box) plus a per-channel decibel trim over -60dB..+30dB, and a shared max-gain range selector — 0.001, 0.01, 0.1, 1, 10, 100 or 1000 — sets how far each fader can travel, so one block covers anything from a gentle blend to heavy amplification. Per-channel mute, bypass and invert switches drop or flip individual sources.
The mixer sums its input channels one sample-frame at a time, scaling each input by its linear gain fader (bounded by the selected max-gain range) and its per-channel decibel setting, then writing the combined result to the mono or stereo output. Because every input is added together per tick, the block sits naturally inside WaveWarp's sample-per-sample engine.
