Analysis of short-term autocorrelation function (From the 'wrassp' package)
acfana.Rdacfana function adapted from libassp
Usage
acfana(
listOfFiles = NULL,
optLogFilePath = NULL,
beginTime = 0,
centerTime = FALSE,
endTime = 0,
windowShift = 5,
windowSize = 20,
effectiveLength = TRUE,
window = "BLACKMAN",
analysisOrder = 0,
energyNormalization = FALSE,
lengthNormalization = FALSE,
toFile = TRUE,
explicitExt = NULL,
outputDirectory = NULL,
forceToLog = useWrasspLogger,
verbose = TRUE
)Arguments
- listOfFiles
vector of file paths to be processed by function
- optLogFilePath
path to option log file
- beginTime
= <time>: set begin of analysis interval to <time> seconds (default: 0 = beginning of file)
- centerTime
= <time>: set single-frame analysis with the analysis window centred at <time> seconds; overrules BeginTime, EndTime and WindowShift options
- endTime
= <time>: set end of analysis interval to <time> seconds (default: 0 = end of file)
- windowShift
= <dur>: set analysis window shift to <dur> ms (default: 5.0)
- windowSize
= <dur>: set analysis window size to <dur> ms; overrules EffectiveLength parameter
- effectiveLength
make window size effective rather than exact
- window
= <type>: set analysis window function to <type> (default: BLACKMAN)
- analysisOrder
= <num>: set analysis order to <num> (default: 0 = sample rate in kHz + 3)
- energyNormalization
calculate energy-normalized autocorrelation
- lengthNormalization
calculate length-normalized autocorrelation
- toFile
write results to file (default extension is .acf)
- explicitExt
set if you wish to override the default extension
- outputDirectory
directory in which output files are stored. Defaults to NULL, i.e. the directory of the input files
- forceToLog
is set by the global package variable useWrasspLogger. This is set to FALSE by default and should be set to TRUE is logging is desired.
- verbose
display infos & show progress bar
Details
Analysis of short-term autocorrelation function of the signals in <listOFFiles>. Analysis results will be written to a file with the base name of the input file and extension '.acf'. Default output is in SSFF binary format (track 'acf').
