Calculates durations for all WAV files referenced in a SAP object's metadata
using parallel processing. Handles missing files gracefully by returning NA
durations and providing warnings.
Usage
compute_wav_durations(x, cores = NULL, verbose = TRUE)
Arguments
- x
A SAP object containing metadata and base path to audio files
- cores
Number of cores to use for parallel processing (NULL for auto-detection: total cores - 1)
- verbose
Logical flag to control progress messages and warnings (default: TRUE)
Value
Returns the modified SAP object with added duration column in metadata containing
wave file durations in seconds. Missing files will have NA durations.
Details
Key features:
Parallel processing implementation using parallel_apply
Automatic core detection with fallback to single-core processing
Progress tracking and missing file warnings
Preserves original object structure while adding duration information
