Evaluates recording files for potential problems. Sound levels are calculated for a small section of each recording file, this is typically done to check for recorder malfunction. Additionally times between the starts and ends of files are calculated, this is typically done to check for gaps in data.
evaluateRecordings(
wavFiles,
sampleWindow = c(60, 120),
octave = c("tol", "ol"),
channel = 1,
freqRange = NULL,
calibration = NULL,
sensitivity = 0,
progress = TRUE
)a dataframe containing the sound level and data gap measurements for each file
file paths to wav files to evaluate, or the directory containing the wav files
start and end (in seconds) of the time window to use
for analysis, e.g. c(40, 100) will use a 60 second window starting
40 seconds into the file
type of sound level to calculate, either 'tol' for
third octave level or 'ol' for octave level
channel of the file to use for analysis
if not NULL, a vector of two numbers giving the
range of frequencies to use for analysis (NULL will use the full
available range)
if not NULL, the frequency dependent calibration
to apply. Must have "frequency" and "gain" (in dB), can either be a .tf
file, a CSV file with columns for frequency and gain, or a dataframe with
columns frequency and gain
the sensitivity of the recording device in dB, this is typically a large negative number
logical flag to show a progress bar
