## rms

rms — Determines the root-mean-square amplitude of an audio signal.

## Description

Determines the root-mean-square amplitude of an audio signal.

## Syntax

    kres rms asig [, ihp] [, iskip]

## Initialization

ihp (optional, default=10) -- half-power point (in Hz) of a special internal low-pass filter. The default value is 10.

iskip (optional, default=0) -- initial disposition of internal data space (see reson). The default value is 0.

## Performance

asig -- input audio signal

rms output values kres will trace the root-mean-square value of the audio input asig. This unit is not a signal modifier, but functions rather as a signal power-gauge.

## Examples

    asrc buzz    10000,440, sr/440, 1 ; band-limited pulse train
    a1   reson   asrc, 1000,100       ; sent through
    a2   reson   a1,3000,500          ; 2 filters
    afin balance a2, asrc             ; then balanced with source
