Load audio file as pladdrr Sound object — av_load_for

Simple wrapper to load audio files directly with pladdrr. Handles time windowing via pladdrr's native extract_part() method.

Usage

av_load_for_pladdrr(
  file_path,
  start_time = 0,
  end_time = 0,
  window_type = "Gaussian1",
  relative_width = 1
)

Arguments

file_path: Character path to audio file (WAV, AIFF, FLAC, MP3, etc.)
start_time: Numeric start time in seconds (default: 0 = beginning)
end_time: Numeric end time in seconds (default: 0 = end of file)
window_type: Character window shape for part extraction (default: "Gaussian1")
relative_width: Numeric relative width of window (default: 1.0)

Value

A pladdrr Sound R6 object

Details

pladdrr reads audio files directly via its C++ backend (no av needed). Supported formats: WAV, AIFF, FLAC, MP3, NIST (via native readers), or any format via av package fallback.

If time windowing is requested (start_time > 0 or end_time > 0), the function uses pladdrr's extract_part() method with appropriate windowing.

Examples

if (FALSE) { # \dontrun{
# Load entire file
sound <- av_load_for_pladdrr("speech.wav")

# Load with time windowing (1.0 to 3.0 seconds)
sound <- av_load_for_pladdrr("speech.wav", start_time = 1.0, end_time = 3.0)

# Use with pladdrr functions
pitch <- sound$to_pitch_cc(time_step = 0.01, pitch_floor = 75, pitch_ceiling = 600)
} # }
