pydiogment.auga

• Description: amplitude based augmentation techniques/manipulations for audio data.

pydiogment.auga.add_noise(infile, snr)

Augment data using noise injection.

Note:

It simply add some random values to the input file data based on the snr.

Args:

• infile (str) : input filename/path.
• snr (int) : signal to noise ratio in dB.

pydiogment.auga.apply_gain(infile, gain)

Apply gain to infile.

Args:

• infile (str) : input filename/path.
• gain (float) : gain in dB (both positive and negative).

pydiogment.auga.fade_in_and_out(infile)

Add a fade in and out effect to the audio file.

Args:

• infile (str) : input filename/path.

pydiogment.auga.normalize(infile, normalization_technique='peak', rms_level=0)

Normalize the signal given a certain technique (peak or rms).

Args:

• infile (str) : input filename/path.
• normalization_technique (str) : type of normalization technique to use. (default is peak)
• rms_level (int) : rms level in dB.
