Audio low-level descriptors (LLDs)

This module encapsulates multiple audio low-level descriptors into a streamlined and modular implementation.

Prerequisites

• librosa
• matplotlib
• numpy

(see requirements.txt. Install with pip install -r requirements.txt)

Importing low-level descriptors

import lowleveldescriptors as lld
descriptors = lld.Audio('path_to_your_audio_file')

# Extract pitch with the pitch detection algorithm (PDA)
descriptors.pda()

Low-level descriptors

Speech

• Average Absolute Amplitude (AAA)
• Root mean square (RMS)
• Zero crossing rate (ZCR)
• Pitch detection algorithm (PDA)
• Harmonic to noise ratio (HNR)

Sound

• Spectral centroid
• Spectral bandwidth
• Spectrograms (Linear, Log-frequency, Mel)
