# DATA_ZWICKER1961 - Data for the Bark scale

## Usage

data = data_zwicker1961;


## Description

data_zwicker1961 returns the data points defining the notion of critical bands. The output data consists of the frequency limit of each band in Hz.

To get the bandwidth of each channel, simply use:

bw = diff(data_zwicker1961);


The first entry has been modified from the original paper: It was originally 20 Hz, but in Zwicker and Fastl 1999 this was changed to 0 Hz.

The data can be plotted using

data_zwicker1961('plot');
