| #define INPUT_RATE_DEFAULT 1000 |
Input rate.
It is an float used by the variable "rate" in the range [INPUT_RATE_DEFAULT/INPUT_RATE_MAX, INPUT_RATE_DEFAULT/INPUT_RATE_MAX] the default value being 1. It represents the ratio of playback speed to nominal speed (bigger is faster).
Internally, the rate is stored as a value in the range [INPUT_RATE_MIN, INPUT_RATE_MAX]. internal rate = INPUT_RATE_DEFAULT / rate variable Default rate value
