pyspeex-noise
Noise suppression and automatic gain control using speex.
from pyspeex_noise import AudioProcessor
auto_gain = 4000
noise_suppression = -30
audio_processor = AudioProcessor(auto_gain, noise_suppression)
# Process 10ms chunks of 16-bit mono PCM @16Khz
while audio := get_10ms_of_audio(): # you define this
assert len(audio) == 160 * 2 # 160 samples
clean_audio = audio_processor.process_10ms(audio)
