6 dB per octave below the cutoff frequency. The same calculation applies to both filters. The calculator assumes a low source impedance, which usually is small enough that it does not change the cutoff frequency. Treble cut - Low pass - RC filter: This RC filter rolls off the frequency res...

1 dB/octave will produce nearly 10 dB difference in desired value between 20 Hz and 20 kHz. Tilt is applied with bass boost and both will affect the bass gain. --sound-signature SOUND_SIGNATURE File path to a sound signature CSV file. Sound signature is added to the compensation curve. ...
Each analytical block comprises one band-pass filter 10, which forms an octave filter bank for restricting the frequency range of the input signal, and a level and frequency calculator 20 which calculates a level value and a single frequency value of the signal whose frequency range has been ...
would simply add the reduction in sensitivity to the measured signal strength. So, for example, if you measured a 150 kHz signal to be 85 dB, you would add another 3 db to get the corrected value of 88 dB. If the signal were at 300 Hz...

Restricting the spectrum to a frequency octave immunizes the system to this harmonic interference. The octave band selected is the lowest band that provides sufficient system information capacity for the multiple carriers, which is in turn determined by the characteristics of the demultiplexing filters....
