NOISE_LOW_LIMIT

#define NOISE_LOW_LIMIT   4000

This file contains a template for the twoloop coder function.

It needs to be provided, externally, as an already included declaration, the following functions from aacenc_quantization/util.h. They're not included explicitly here to make it possible to provide alternative implementations:

• quantize_band_cost
• abs_pow34_v
• find_max_val
• find_min_book
• find_form_factorFrequency in Hz for lower limit of noise substitution
