# sig_transposedtone - Transposed tone test stimuli

## Usage

ts = sig_transposedtone(fc,fm,dur,fs);


## Input parameters

 siglen Length of signal fc Vector of carrier frequencies (Hz) fm Vector of modulation frequencies (Hz) fs Sampling frequency (Hz)

## Output parameters

 outsig transposed tone (column vector)

## Description

sig_transposedtone(siglen,fc,fm,dur,fs) generates a transposed tone test stimuli as defined in Kolrausch et. al (1997).

By default, the output is normalized to have an RMS value of 1, but this can be changed by passing any of the flags from the normalize function.

Some example parameters as used in a study by Santurette:

siglen = 44100;
fc     = 5000;
fm     = 435;
fs     = 44100;
outsig = sig_transposedtone(fc,fm,dur,fs);
