improve the accuracy of silence detection process. Let SW =EW •ZCRW where EW 1 and ZCRW are respectively the normalized energy, and the Zero Crossing Rate of the window “W”. Thresholding SW could extract silence segments. Fig2.1, background noise – music (a), and detection using our variable “S” ( b ), and by simply

Given sampling rate of 8000 it will split the audio by detecting audio lower than 40db for period of 1 sec. Or, you can trim the audio "silent parts" using: librosa.effects.trim(y=buffer, frame_length=8000, top_db=40)

Silence/noise detection for speech and music signals. Abstract:This paper introduces a novel off-line algorithm for silence/noise detection in noisy signals. The main concept of the proposed algorithm is to provide noise patterns for further signals processing i.e. noise reduction for speech enhancement. The algorithm is based on frequency domain characteristics of signals.

Silence detection and removal is an essential building block of any multimedia video conferencing system. It reduces the bandwidth requirements of the underlying network transport service and helps to maintain an acceptable end-to-end delay for audio. We analyze the requirements for a silence detection algorithm hosted on a multimedia communication system, …
