functional_detect_pitch_frequency: Detect Pitch Frequency (functional)

In torchaudio: R Interface to 'pytorch''s 'torchaudio'

Detect Pitch Frequency (functional)

Description

It is implemented using normalized cross-correlation function and median smoothing.

Usage

functional_detect_pitch_frequency(
  waveform,
  sample_rate,
  frame_time = 10^(-2),
  win_length = 30,
  freq_low = 85,
  freq_high = 3400
)

Arguments

waveform	(Tensor): Tensor of audio of dimension (..., freq, time)
sample_rate	(int): The sample rate of the waveform (Hz)
frame_time	(float, optional): Duration of a frame (Default: 10 ** (-2)).
win_length	(int, optional): The window length for median smoothing (in number of frames) (Default: 30).
freq_low	(int, optional): Lowest frequency that can be detected (Hz) (Default: 85).
freq_high	(int, optional): Highest frequency that can be detected (Hz) (Default: 3400).

Value

Tensor: Tensor of freq of dimension (..., frame)
