Hi,
I'm trying to play 32-bit stereo and 24 bit stereo WAV files. As audio driver
can only support 16-bit, so I use below conversion functions. The ouput seems
to be fine but with lot of noise. Any ideas ?
static void convert_24_to_16sle(short *out, unsigned long len, char *in)
{
int nr_of_samples;
int i;
nr_of_samples = len / 3;
for (i = 0; i < nr_of_samples; i++) {
*out = ((short)in[1] | ((short)in[2] << 8));
out++;
in += 3;
}
}
static void convert_32_to_16sle(short *out, unsigned long len, char *in)
{
int nr_of_samples;
int i;
nr_of_samples = len / 4;
for (i = 0; i < nr_of_samples; i++) {
*out = (short)(*((unsigned long *)in) >> 8);
out++;
in += 4;
}
}
