Matlab code is in description of this video. load handel.mat yRange -0.7,0.
Scale Selected Audio Data Play an excert from Handel's Hallelujah Chorus at 70 of its original volume. The shape of your graph should not change, since you have not altered any data, but simply changed the number of samples player per second. MATLAB plays the scaled audio with a bit depth of 16 bits per sample, if this bit depth is supported on your system. And then, in function Callback of the button created to stop the song, type: Theme Copy clear sound - 2 method This method is the best, in my opinion. Sampling and aliasing explained using audio signal in a MATLAB simulation. you can slow down or speed up the sound file by altering the frequency, in other words, changing your fs should do the trick.
#PLAY SOUND IN MATLAB HOW TO#
%File to play my voice to tell me to keep studyingīasically my question is is there a way to keep writing my same sound file to a different name, and then continuously play the new file? I thought about making a matrix, and then just use a "for" loop to traverse it then play the new file, but I don't know how to make a matrix out of sound files. In function Callback of the button created to play the song, type: Theme Copy sound (y, Fs, nBits) nBits usually is seted to 16 bits. However, when my program tries to replay the sound I get this error: ? Error using =>Īdioplayer>audioplayer.resume at 710Ī given audio device may only be opened once.Īdiorecorder>ay at
Right now I have it set to play every couple of seconds, just to get some bugs out of the system. I'm trying to create a MATLAB program to play a sound over and over again every couple of minutes.
