Yes, resample is your function. To downsample x from 44100 Hz to 22050 Hz: y = resample (x,1,2); (the "1" and "2" arguments define the resampling ratio: 22050/44100 = 1/2) To upsample back to 44100 Hz: x2 = resample (y,2,1); Note that the resample function includes the necessary anti-aliasing (lowpass) filter.

The sampling freq of these files are 48k. I need to read all the audio files one by one and resample them to 8k and then write all output audio files in different folder. For the single file, i did like this but i need to do for all.
Resampling - MATLAB & Simulink - MathWorks
https://www.mathworks.com/help/signal/ug/resampling.html
The basic syntax for resample is. y = resample (x,p,q) where the function resamples the sequence x at p/q times the original sample rate. The length of the result y is p/q times the length of x. One resampling application is the conversion of digitized audio signals from one sample rate to another, such as from 48 kHz (the digital audio tape standard) to 44.1 kHz (the compact disc …

For the single file, i did like this but i need to do for all. [y,Fs] = audioread('C_01_ECHO_FA.wav'); y_resamp = resample(y,8000,48000); audiowrite('C_01_ECHO_FA_new.wav',y_resamp,8000); Best Answer. This should do what you want. [y,fs]=audioread('file48000.wav'); audiowrite('file8000.wav',y,8000); Related Question.
