hz2erb, erb2hz

Convert all elements of x from Hertz to ERB (equivalent rectangulare bandwidth) Bark and vice versa.

Usage

hz2erb(x)

erb2hz(x)

x

a scalar, vector or matrix

Result

The result r has the same type as x and contains the converted elements of x.

hz2bark

Uses the algorithm published by Zwicker and Fastl (1990) to convert frequencies from Hz to Bark:

r_i,j = 13 * atan(0.76*x_i,j/1000) + 3.5 * atan((x_i,j/7500)^2)

bark2hz

Because the above formula is not directly invertable, an iteration algorithm is used to convert the x_i,j from Bark to the result r_i,j in Hz.

Note: Both functions are also available in the expressions used in the NUM and INT command.
