Microphone frequency response correction profile.
Each profile provides 16-channel gain corrections to flatten the frequency response of a specific microphone. Derived from manufacturer datasheet data.
Set on Processor via setMicProfile() — the correction is applied inside EqualizerDetector before per-bin normalization.
| Enumerator |
