- * Create a new Delay Locked Loop time filter
- *
- * feedback2_factor and feedback3_factor are the factors used for the
- * multiplications that are respectively performed in the second and third
- * feedback paths of the loop.
- *
- * Unless you know what you are doing, you should set these as follow:
- *
- * o = 2 * M_PI * bandwidth * period_in_seconds
- * feedback2_factor = sqrt(2) * o
- * feedback3_factor = o * o
- *
- * Where bandwidth is up to you to choose. Smaller values will filter out more
- * of the jitter, but also take a longer time for the loop to settle. A good
- * starting point is something between 0.3 and 3 Hz.
- *
- * @param time_base   period of the hardware clock in seconds
- *                    (for example 1.0/44100)
- * @param period      expected update interval, in input units
- * @param brandwidth  filtering bandwidth, in Hz
- *
- * @return a pointer to a TimeFilter struct, or NULL on error
- *
- * For more details about these parameters and background concepts please see:
