Volume control/limiter block
The "volume limiter" block is a peak and/or RMS-based limiter, typically at the end of a DSP flow, that helps
keep signal levels, on average, below a certain level. A limiter can be extremely useful in audio applications;
from driving loudspeakers within its rated power, keeping the amplifier IC temperature controlled to making
music and voice sound louder and more intelligible.
