hz2erb, erb2hz

Convert all elements of x from Hertz to ERB (equivalent rectangulare bandwidth) 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.

hz2erb

r_i,j = 16.7 * log₁₀(1 + x_i,j / 165.4)

erb2hz

r_i,j = 165.4 * (10 ^ (0.06 * x_i,j) - 1)

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.
