MATLAB: Handling audio files

noise removal

I'm working with audio files for noise reduction. I have my audio file and reference signal of different lengths. How to make the input and desired vectors of same length in matlab?

Best Answer

Check this out:

% v1, v2 - two vectors are given
len1=length(v1);
len2=length(v2);
%
LEN=min(len1, len2);
V1=v1(1:LEN);
V2=v2(1:LEN);
% V1, V2 are vectors with same length

Try this:

% Define component cell arrays.
v1 = {'a'; 'b'; 'c'}
v2 = {'d'}
v3 = {'e'; 'f'}
% Find out how  big cell array needs to be.
lv1 = length(v1);
lv2 = length(v2);
lv3 = length(v3);
rows = max([lv1,lv2,lv3])
% Instatiate cell array of the max size.
v4 = cell(rows, 3)
% stuff each column in.
v4(1:lv1, 1) = v1;
v4(1:lv2, 2) = v2;
v4(1:lv3, 3) = v3;
% Print out results
fprintf('\n\nHere is the output cell array:\n');
v4

In the command window:

Here is the output cell array:

v4 = 
    'a'    'd'    'e'
    'b'     []    'f'
    'c'     []     []
