## spechist

spechist — Accumulates the values of successive spectral frames.

## Description

Accumulates the values of successive spectral frames.

## Syntax

    wsig spechist wsigin

## Performance

wsigin -- the input spectra.

Accumulates the values of successive spectral frames. At each new frame of wsigin, the accumulations-to-date in each magnitude track are written to the output spectrum. This unit thus provides a running histogram of spectral distribution.

## Examples

      wsig2    specdiff    wsig1         ; sense onsets
      wsig3    specfilt    wsig2, 2      ; absorb slowly
               specdisp    wsig2, 0.1    ; & display both spectra
               specdisp    wsig3, 0.1
