blocksize: Select the Blocksize. This defines the size of the sent audio packages. You can choose a Blocksize between 64 and 4096 samples. A higher Blocksize might make your connection more stable, nevertheless, it also adds latency. We usually work with a Blocksize of 64 or 128 samples. Each peer can choose their own Blocksize.
recv buffer: Choose the ‘receive buffer’ by writing a number in milliseconds. This defines the buffer queuing and helps to circumvent internet jitter in the audio connection from the remote peer(s). If you hear drops in the incoming audio signal, you can increase the receive buffer. Nevertheless, a higher receive buffer also leads to higher latency. Each peer can choose their own receive buffer.
The resolution is preset to 16 bits and cannot be changed; the sample rate is given by your audio settings (see Section 2a above).
