Level Detection

audio_dspy has support for audio level detection, similar to what might be used for a compressor, limiter, gate, or other similar dynamics processor.

Processing Audio

Processing audio through a level detector can be implemented as follows:

from scipy.io import wavfile
fs, x = wavfile.read('drums.wav')
x = adsp.normalize(x[:,0])
plt.plot(x, label='input')

for mode in ['peak', 'rms', 'analog']:
    y = adsp.level_detect(x, fs, mode=mode)
    plt.plot(y, label=mode)

plt.title('Level Detection Example')
plt.xlabel('Time [samples]')
plt.legend()
