Function reassigned_spectrogram

Source 
pub fn reassigned_spectrogram(
    y: &[f32],
    sr: Option<u32>,
    n_fft: Option<usize>,
) -> Result<Array2<f32>, AudioError>
Expand description

Computes a reassigned spectrogram for improved time-frequency resolution.

§Arguments

  • y - Input signal as a slice of f32
  • sr - Optional sample rate in Hz (defaults to 44100)
  • n_fft - Optional FFT window size (defaults to 2048)

§Returns

Returns a Result containing an Array2<f32> representing the reassigned spectrogram, or an AudioError if computation fails.

§Errors

  • AudioError::InsufficientData - If signal length is less than n_fft.
  • AudioError::ComputationFailed - If STFT computation fails.

§Examples

let signal = vec![1.0; 4096];
let reassigned = reassigned_spectrogram(&signal, None, None).unwrap();
