Black line: unfiltered, uncentered breathing trace.
Green lines: stimulus onset for this trial, and for next trial.
Red/blue lines: expirations/inspirations.
Pulled out as "zero-crossings" (45th percentile) of 50Hz lowpass-filtered breathing. Computed for
each audio file. Currently no correction for duration, etc.
y-value corresponds to 45th percentile of filtered waveform.
Filter Description:
Stim phase: whether stimulation occured during inspiration or expiration. "Error" if breath segmentation
failed for some reason.
Putative call: whether this trial contains breath amplitude in 98th percentile of file (Not all trials
pulled out actually have a call).
Wav filename: matches any part of original wav filename.
