Hii everyone

i wanna ask you

How to trim audio in Matlab to get the desired audio duration?

for example, the original audio duration is 17.9984 seconds and we want to cut it to 17.5500 seconds

thank you

Express the desired length in thems of samples (here ‘Fs’ is the smapling frequency in Hz) —

desiredLength = 17.5500;                        % Seconds
L = Fs * desiredLength;                         % Samples/sec * sec = Samples
trimmedAudioMatrix = OriginalAutoioMatrix(1:L,:)

.

Alright Mr, thank you

it works

But I want to ask you one more question

How do I change the Fs(sampling frequency ) according to what I want Mr?

for example, the original audio Fs is 16000Hz and we want to changed it to 44100Hz

Thank you Mr

You can use the resample function: https://www.mathworks.com/help/signal/ref/resample.html

[x,fs] = audioread(<path_to_file>);
p = 44100; q = fs;
y = resample(x,p,q); % y is not at 44100Hz.

@Srikar Sastry is correct. The resample function will work here.
