Separates a Wave object into windows of a defined length and runs a function on the window section. Windows may overlap, and the function can make use of 'parallel' package for multi-core processing. It will also show a progress bar if the 'pbapply' package is installed.
Usage
windowing(
wave,
window.length = 1000,
FUN,
window.overlap = 0,
bind.wave = FALSE,
complete.windows = TRUE,
cluster = NULL,
...
)
Arguments
- wave
A Wave object or filename. Using filenames may save loading an entire large file into memory.
- window.length
The length of the analysis window (in samples).
- FUN
FUN to be applied to windows.
- window.overlap
The overlap between successive windows (in samples), a negative value will result in a gap between windows.
- bind.wave
If TRUE and FUN returns wave objects, then these are combined into a single object
- complete.windows
If TRUE (default) the final window will not be processed unless it has a length equal to window.length.
- cluster
A cluster form the 'parallel' package for multi-core computation.
