Illustration of the extraction procedures applied to recording FFRs. Left row represents waveforms of FFR data at every extraction stage, and right row represents the corresponding spectrograms of FFR data at the same stage. Waveforms of signal from top to bottom are raw FFR data, subtracted data, wiener filter data, lowpass filtered data, and time-compensated data
