Sender algorithm (audio):

1. Capture N samples.
2. Compute the D-levels DWT of the array of samples. The DWT should be orthogonal.
3. Compress the samples (now represented by an array of DWT coefficients) using a bit-plane encoder. Supose P planes. Generate a packet of code-stream for every plane of bits.
4. X <- P-1.
5. Send X+1 packets over UDP.
6. Given a maximum latency L, receive (over UDP) the number of packets X transmitted on time (before the maximum latency).
7. Go to step 5.
