Batch Process Sounds in Parallel — process_sounds

Apply analysis to pre-loaded Sound objects in parallel. Use when sounds are already in memory.

Usage

process_sounds_parallel(
  sounds,
  analysis_func,
  n_cores = NULL,
  threads_per_worker = NULL,
  ...
)

Arguments

sounds: List of Sound objects or external pointers
analysis_func: Function. Analysis function to apply. Should accept a Sound object/pointer and return results.
n_cores: Integer. Number of CPU cores (default: auto)
threads_per_worker: Integer or `NULL`. C++ threads each worker may use for Praat kernels. `NULL` (default) auto-divides cores among workers to avoid oversubscription; set `1` to force single-threaded workers.
...: Additional arguments passed to analysis_func

Value

List of results

Examples

# \donttest{
sounds <- list(
  Sound$create_tone(frequency = 220, duration = 0.2),
  Sound$create_tone(frequency = 440, duration = 0.2)
)

# Process using at most 2 cores (CRAN example policy)
results <- process_sounds_parallel(sounds, function(s) {
  pitch <- s$to_pitch()
  pitch$get_mean(0, 0, "hertz")
}, n_cores = 2)
#> Processing 2 sounds using 2 cores (2 thread(s)/worker)
# }
