EQ curve and spectrum
Why can an EQ boost raise Peak?
EQ response
InputOutput
- Gain at the center frequency
- 3.00 dB
- Input waveform Peak
- -7.93 dBFS
- Output waveform Peak
- -6.92 dBFS
Boost increases sines near the center frequency. Their combined amplitude and phase change waveform Peak; an EQ gain value is not the overall Peak.
An RBJ peaking bell filter at 48 kHz, not native pedal voicing. The spectrum shows five synthetic sine waves; a sine or bin amplitude is not the filtered-band Peak in a Rigs meter.
How to read this experiment
The lab filter is not engine voicing. An FFT-bin amplitude is not filtered-band Peak and does not guarantee that the cause of overload can be identified.
