`functional_detect_pitch_frequency.Rd`

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

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

- 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`

).

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