Matlab question:

clc close all clear all [inputData, fsample] = audioread('EA.wav');

I want to take inputData and shift all frequencies by an amount.

Positive Frequency shift +500Hz

Eksample: if i have a frequency range from 50 to 1000 in inputData.... i want to shift it, so the frequency range ends up as 550 to 1500.

Negative frequency shift -40 Hz

Eksample 2: if i have a frequency range from 50 to 1000 in inputData... i want to shift it, so that frequencies end up in the range of 10-960.
