Convert pladdrr data frame to superassp format — pladdrr_df_to

Converts data frames from pladdrr (long format with time/frequency/value) to superassp's wide format expected for AsspDataObj tracks.

Usage

pladdrr_df_to_superassp(
  df,
  type = c("pitch", "formant", "intensity"),
  n_formants = 5
)

Arguments

df: Data frame from pladdrr R6 object's as_data_frame() method
type: Character indicating data type: "pitch", "formant", "intensity"
n_formants: Integer number of formants (default: 5, for formant data only)

Value

Data frame in wide format suitable for AsspDataObj

Details

Transformations by type:

Pitch: pladdrr returns (time, frequency) → superassp expects (time, F0)

Formant: pladdrr returns (time, formant_number, frequency, bandwidth) → superassp expects (time, fm1, fm2, ..., fm5, bw1, bw2, ..., bw5)

Intensity: pladdrr returns (time, intensity) → superassp expects same

Examples

if (FALSE) { # \dontrun{
sound <- pladdrr::Sound("audio.wav")
pitch <- sound$to_pitch_cc()
pitch_df <- pitch$as_data_frame()
wide_df <- pladdrr_df_to_superassp(pitch_df, type = "pitch")
} # }
