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

Usage

hz2erb(x)

erb2hz(x)

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); x_i,j is the frequency in Hz and must be greater than 0
erb2hz: r_i,j = 165.4 * (10 ^ (0.06 * x_i,j) - 1); x_i,j is the frequency in ERB and must be greater than 0
