Public Member Functions | |
| GoertzelConfig (const AudioInfo &info) | |
| Copy constructor from AudioInfo. | |
| virtual void | clear () |
| void | copyFrom (AudioInfo info) |
| Same as set. | |
| bool | equals (AudioInfo alt) |
| Returns true if alt values are the same like the current values. | |
| bool | equalsExSampleRate (AudioInfo alt) |
| Checks if only the sample rate is different. | |
| virtual void | logInfo (const char *source="") |
| operator bool () | |
| Returns true if all components are defined (no component is 0) | |
| bool | operator!= (AudioInfo alt) |
| Returns true if alt values are the different from the current values. | |
| bool | operator== (AudioInfo alt) |
| Returns true if alt values are the same like the current values. | |
| void | set (AudioInfo info) |
| Copies the values from info. | |

Detailed Description
Configuration for Goertzel algorithm detectors.
This structure extends AudioInfo to include Goertzel-specific parameters. It defines the frequency detection behavior, audio format, and processing parameters for the Goertzel algorithm implementation.

◆ block_size
| int block_size = 205 |
Number of samples to process per block (N) - affects detection latency and accuracy
◆ threshold
| float threshold = 0.5f |
Detection threshold for magnitude (normalized samples, typically 0.1 to 1.0)
