Extract All Acoustic Features for TextGrid Intervals (Batch, SIMD) — textgrid_interval_all_features

Comprehensive batch extraction of pitch, formant F1/F2, and intensity statistics for all intervals in a single call, as an alternative to calling `textgrid_interval_pitch_batch()`, `textgrid_interval_formant_batch()`, and `textgrid_interval_intensity_batch()` separately.

Usage

textgrid_interval_all_features_batch(
  textgrid_xptr,
  pitch_xptr = NULL,
  formant_xptr = NULL,
  intensity_xptr = NULL,
  tier_number = 1L
)

Arguments

textgrid_xptr: External pointer to TextGrid
pitch_xptr: External pointer to Pitch (optional)
formant_xptr: External pointer to Formant (optional)
intensity_xptr: External pointer to Intensity (optional)
tier_number: Tier number (1-based)

Value

Data frame with all available features per interval

Details

Duration calculation and statistics aggregation use SIMD where applicable.

Examples

sound <- Sound$create_tone(frequency = 180, duration = 1.0)
pitch <- sound$to_pitch()
formant <- sound$to_formant_burg()
intensity <- sound$to_intensity()
tg <- textgrid_create(0, 1, "phones")
tg$insert_boundary("phones", 0.5)
tg$set_interval_text("phones", 1, "a")
tg$set_interval_text("phones", 2, "b")

stats <- textgrid_interval_all_features_batch(
  tg$.xptr, pitch$.xptr, formant$.xptr, intensity$.xptr, tier_number = 1
)
