I wrote a simple c++ program to generate a sine wave and write it to a signed 16 bit raw audio file: #include <fstream.h> #include <math.h> void main() { short wave[11025]; ofstream output("temp.raw", ios::binary); for (int sample = 0; sample < 11025; sample++) { wave[sample] = (short) (32767*sin(.01*sample)); output << wave[sample]; } } ..but it just produces noise. If the short (int) type is 2 bytes long, why won't this work? It works for an 8 bit file (char, if some numbers are changed).
