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 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)
