#define | INITIAL_SAMPLE_BUFFER_SIZE 512000 |
| Initial size of the sample buffer which is used for decompression of compressed sample wave streams - this value should always be bigger than the biggest sample piece expected to be read by the sampler engine, otherwise the buffer size will be raised at runtime and thus the buffer reallocated which is time consuming and unefficient.

#define | GIG_EXP_DECODE(x) (pow(1.000000008813822, x)) |
