DeBird

Premium and Ultimate Edition Only

This feature is available in the Premium and Ultimate Editions only.

DeBird reduces unwanted bird song from recordings. The algorithm is based on deep learning and has been trained to separate bird noise from other sounds using an extensive training set. The default setting will immediately and fully automatically reduce bird noise. In many cases, however, you might not want to remove the noise entirely. You can also adjust the sensitivity of the bird noise detection. The sensitivity is adjustable for the full frequency spectrum or in frequency bands. A spectrum analyzer analyzes the incoming audio signal (the filled gray curve) and indicates the removed signal (the yellow curve):

Parameter Settings

• Sensitivity Curve

The sensitivity filter allows you to control the noise sensitivity in adjustable frequency bands. There are three filters available that you can toggle on or off using the buttons in the lower left corner of the spectrum analyzer:

• A low shelf filter
• A peak filter
• A high shelf filter

These work the same way as in parametric equalizers. You can modify the filter characteristics by clicking the handles (colored bullets) in the curve and move them around and the current frequency and gain settings of the frequency band is displayed. You can also change the filter slopes or the bandwidth of the peak filters. Click the handle of the filter you wish to modify. Arrows surrounding the handle will appear that you can use to change the bandwidth or the filter slope of the selected filter.

The sensitivity curve lets you change the noise sensitivity in separate frequency bands.

• Noise Floor slider (dB)

In many cases, it is desirable to leave some noise in the signal. You can use the Noise Floor slider to control this. The Noise Floor is set in dB specifies the maximum attenuation of the frequency components.

If you hear artifacts in your output signal, try increasing the Noise Floor slider to reduce the maximum amount of attenuation.

• Solo Noise

Click the headphones icon in the bottom right corner of the interface if you wish to monitor the noise signal that was removed.
