== Details == thumb|500px|Block diagram of the SILK encoder Skype Limited announced that SILK can use a sampling frequency of 8, 12, 16 or 24 kHz and a bit rate from 6 to 40 kbit/s. It can also use a low algorithmic delay of 25 ms (20 ms frame size + 5 ms look-ahead). The reference implementation is written in the C programming language. The codec technology is based on linear predictive coding (LPC). The SILK binary SDK is available.
