Config

config

Configuration dataclass for PyGaborSTM.

Default values match Bellur & Elhilali (2017).

Config dataclass

Config(use_gpu: bool = False, sample_rate: int = 16000, n_filters: int = 128, f_min: float = 180.0, octaves: float = 5.3, tau_ms: float = 8.0, frmlen_ms: float = 16.0, rates: ndarray = (lambda: copy())(), scales: ndarray = (lambda: copy())(), resolution: str = 'low', rsf_frame_size_ms: int = 500, rsf_frame_shift_ms: int = 10)

Configuration for the full PyGaborSTM pipeline.

PARAMETER	DESCRIPTION
use_gpu	If True, use CuPy for GPU acceleration. Silently falls back to NumPy with a warning if CuPy is unavailable. TYPE: bool DEFAULT: False
sample_rate	Audio sample rate in Hz. Must match the input signal. TYPE: int DEFAULT: 16000
n_filters	Number of cochlear (gammatone) channels in the spectrogram stage. TYPE: int DEFAULT: 128
f_min	Lowest filter center frequency in Hz. TYPE: float DEFAULT: 180.0
octaves	Total frequency range in octaves. f_max = f_min * 2**octaves. TYPE: float DEFAULT: 5.3
tau_ms	Time constant (ms) for the leaky-integration stage of the spectrogram. TYPE: float DEFAULT: 8.0
frmlen_ms	Spectrogram frame length in ms (downsampling factor after y5). TYPE: float DEFAULT: 16.0
rates	Base set of temporal modulation rates (Hz). Used as anchor points; resolution may interpolate additional rates between them. TYPE: ndarray DEFAULT: ``STANDARD_RATES``
scales	Base set of spectral modulation scales (cycles/octave). Anchor points for resolution interpolation. TYPE: ndarray DEFAULT: ``STANDARD_SCALES``
resolution	Density multiplier for the rate and scale grids. Each level doubles the number of kernels along both axes. TYPE: (low, medium, high, ultra, max, overkill) DEFAULT: "low"
rsf_frame_size_ms	RSF integration window length in ms. TYPE: int DEFAULT: 500
rsf_frame_shift_ms	RSF hop size in ms. TYPE: int DEFAULT: 10
