i write a matlab code to take input though sound card. When i run this code i get 2 type of error in two different PC,s Please help me for this any one Code is this
AI=analoginput('winsound'); addchannel(AI,1); Fs = 8000; set(AI,'SampleRate',Fs) duration = 2; set(AI,'SamplesPerTrigger',duration*Fs); start(AI); data=getdata(AI); delete(AI) xfft = abs(fft(data)); mag = 20*log10(xfft); mag = mag(1:end/2); [ymax,maxindex]=max(mag);
When i Run this I get this error
Error ??? Error: "data" was previously used as a variable, conflicting with its use here as the name of a function or command. See MATLAB Programming, "How MATLAB Recognizes Function Calls That Use Command Syntax" for details.
This error in old pc and second error in new pc is this
??? Error using ==> playsnd Frequency must be a scalar
Error in ==> sound at 58 playsnd(y,fs,bits);
