Detailed Description

Internal echo canceller state structure.

Contains all internal state variables and buffers for the MDF (Multi-Delay block Frequency adaptive filter) echo cancellation algorithm. This structure should never be accessed directly by users; use the EchoCanceller class methods instead.

Warning: Direct access to this structure is not recommended and may break encapsulation.

The documentation for this struct was generated from the following file:
