hi dears

I'm new to labview

how can i integrate this matlab code to labview

I want to create a flute tone using labview ...Please any idea's about sound and music will be great.

with best regards to u all .

s = 44100; % sample rate

T = 1/fs; % sample period

t = [0:T:2.0]; % signal duration (seconds)

fm = 4; % modulation frequency

fc = 440; % carrier frequency

% A en m zijn afvallende e-machten y(t)=exp(-t/iau)

A = 0.9*exp(-0.001/0.1); % unmodulated carrier amplitude

m = 0.7; % modulation index

% modulation signal

xm = m * A * sin(2*pi*fm*t);

% amplutide modulation

xc = (A + xm) .* sin(2*pi*fc*t);

% ring modulation

%xc = xm .* sin(2*pi*fc*t);

subplot(2, 1, 1)

plot(t, xc)

xlabel('Time (seconds)')

ylabel('Amplitude');

axis([0, 0.2, -1.6, 1.6]); % zoom in display

subplot(2, 1, 2)

N = length(t); % N = length of fft

f = [0:N-1] * fs / (N-1); % frequency vector

X = abs(fft(xc)) / N;

plot(f, X);

xlabel('Frequency (Hertz)');

ylabel('Magnitude Gain');

axis([0,1000,0,max(X)]); % zoom in display

grid

sound(xc,fs)

Go to Find Examples in the Labview Help menu.

Search for Matlab. Open MATLAB Script - Fractal example.

If you have Matlab installed on the system, and are using the Matlab script node within Labview, it will launch an instance of Matlab and execute whatever you put into the script node.

I see you have LV7.1.

If you are able to get LV8.0/8.20 Student edition, you may be able to run the Matlab code as is in a MathScript structure. It may require some modification.

Hello Kameran,

I tried to interpred your matlab code and give you a simple sample in labview.

Please let me know if it is what you want .

Hi Dears ..thanks for all your tips

I have tried JohnS example , thanks ...

f(t)=a*sin(2*pi*f*t)

f=130 roughly c8 on he organ keyboard

continous time =10000

i don't know what is wrong here , when i want to change the values exp. frequency ...it doesn't change the sound .

Hi Kameran,

use 'execution high lighting' and see what is wrong, then do a search on Data-Flow programming.

Hello Kamaran,

You can't change anything if the controls are outside the loop, and the vi is running.

I can't check this vi, i don't have (want) Matlab installed at home.

I think you need to think differently, but i'm not convinced what i am thinking is a correct thought !

Success!
