Audio / .Net Audio Issue on Live Stream

« on: May 05, 2017, 04:40:06 pm »

Hello,

Im really fresh to SFML, so first I want to say thanks for such a great Project.
Actually, Im implementing a Live Voice-Chat over the Internet(with SFML.Net) and already got it working.

When the Voice-Packet is send over the Network, it will be handled by the server which returns it with some more informations. On Client Side I extract these informations and call a Sound-Playing-Function with the voice samples as a byte array(for networking).
Well the packets coming in right here are in a really short intervall (100ms)

this code handles the packets and playing them:

private void PlayAudioData(byte[] data, float[] myposition, float[] mydirection, float[] talkerposition, bool self)
        {
            //set my position
            Listener.Position = new Vector3f(myposition[0], myposition[1],myposition[2]);
            //rotation not implemented in protocol right now
            Listener.Direction = new Vector3f(mydirection[0], mydirection[1], mydirection[2]);
            //if i muted the speaker then dont play
            if (outMuted)
                return;
            //convert audio data back to short
            short[] sdata = new short[(int)Math.Ceiling((double)data.Length / 2)];
            Buffer.BlockCopy(data, 0, sdata, 0, data.Length);
            //load into the buffer
            buffer = new SoundBuffer(sdata, 1, this.SampleRate);
            sound = new Sound(buffer);
           
            //set speakers position
            if(self)
                sound.Position = new Vector3f(talkerposition[0]+1, talkerposition[1]+1, talkerposition[2]+1);
            else
                sound.Position = new Vector3f(talkerposition[0], talkerposition[1], talkerposition[2]);
            sound.RelativeToListener = false;
            sound.MinDistance = 1f;
            //loudness regulation, lower value = louder sound from distance
            sound.Attenuation = 4;
            sound.Play();
        }

the Problem is, that after each Sound.Play, a short clicking sound appears (like abrupt voice-stopping).
With 100ms packets right here, this disturbing sound appears 10 times a second.

Is there a way to solve this problem?

thanks
