How to can I change axis from samples to time?

19 views (last 30 days)
I have loaded my audio file with the following code "handles.myRecording = audioread (uigetfile('*.*','Load a File'));" Next I use "plot(handles.myRecording);" to plot the graph, but the x axis is in samples. How can I change it to time?

You should also have a sampling frequency (Fs) variable in your audio file. To convert the index vector to a time vector:
samples = 0:10; % Sample Indices Vector
Fs = 44100; % Sampling Frequency (Hz)
t = samples/Fs; % Time Vector (seconds)
I assume a value for ‘Fs’ here, yours may be different.
