# acousticProminenceRatio

## Syntax

## Description

`[`

also returns a logical vector specifying which frequencies are prominent tones according to
ECMA-418-1.`pr`

,`prFreq`

,`isProminent`

] = acousticProminenceRatio(`audioIn`

,`fs`

)

`[`

measures the prominence ratios in a time-varying signal. This syntax also returns a vector
of timestamps for each time segment in the input signal.`pr`

,`prFreq`

,`isProminent`

,`timestamps`

] = acousticProminenceRatio(`audioIn`

,`fs`

,`TimeVarying`

=true)

`[___] = acousticProminenceRatio(___,`

specifies options using one or more name-value arguments. For example,
`Name=Value`

)`acousticProminenceRatio(x,fs,FFTLength=2048)`

computes the prominence
ratios with an FFT length of 2048.

`acousticProminenceRatio(___)`

with no output arguments
plots the prominence ratios of the frequencies in the signal.
