I will use NAudio in my project and I got a problem now.
I want WaveOut to play only one channel data (eg. right channel) when WaveStream is a stereo wave stream (mp3 encoding). How I can let WaveOut to filter it?
internal bool OnDone()
{
int bytes;
lock (waveStream)
{
bytes = waveStream.Read(buffer, 0, buffer.Length);
}
if (bytes == 0)
{
return false;
}
else
{
//Edit by charley at 2013/4/9
//左右声道是交替出现的，所以在间隔处用0填充
if (VolumnMode != 1)
{
for (int i = 0; i < bytes - 1; i += mVolumnSize)
{
if (VolumnMode == 2)
{
for (int j = 0; j < mVolumnSize; j++)
{
buffer[i + j] = mLeftVolumn ? buffer[i + j] : (byte)0;
}
mLeftVolumn = !mLeftVolumn;
}
if (VolumnMode == 3)
{
for (int j = 0; j < mVolumnSize; j++)
{
buffer[i + j] = !mLeftVolumn ? buffer[i + j] : (byte)0;
}
mLeftVolumn = !mLeftVolumn;
}
}
}
for (int n = bytes; n < buffer.Length; n++)
{
buffer[n] = 0;
}
}
WriteToWaveOut();
return true;
}
The headphone is not usb , and i dont get any event.
Its connected with jack .

You can use the MediaFoundationReader (currently in 1.7 preview release only) to do thisWhere can I download NAudio 1.7 ?
