Visualizing Filters (Patreon)

This video tutorial demonstrates how to visualize and understand the behavior of different filters in Bitwig using a Poly grid and a spectrum analyzer. Here's a summary:

1. Setting Up the Test Environment:Utilize a bully grid and a spectrum analyzer with specific settings (large resolution, slow speed, 3 dB/octave tilt for pink noise).
   Create a sine oscillator modulated by an LFO to observe filter effects.
   
2. Using Comp Filter:Apply a comb filter, adjusting volume and feedback.
   Observe the comb filter's effect in the frequency spectrum, particularly its ability to create overtones and harmonics, useful for physical modeling.
   
3. Exploring Different Filters:Experiment with various filters like 'Fizz' and observe changes in frequency domain.
   Adjust parameters to see real-time changes in the spectrum.
   
4. Visualizing Filter Effects:Compare visual representations of filters in Bitwig with other software like Serum.
   Note the use of reverb filters and convolution for different sound modeling.
   
5. Understanding Filter Characteristics:Analyze different filters, such as 'Rasp', to understand their unique features and frequency responses.
   Observe how adjusting filter settings alters the sound spectrum.
   
6. Investigating Further:Examine different modes and types of filters (e.g., bandpass, low pass) and their impact on sound.
   Notice how changing filter poles affects steepness and sound character.
   
7. Conclusion:Emphasizes the importance of visualizing filters for a better understanding of their impact on sound.
   Encourages experimentation with various settings to explore different sound textures.
   

This tutorial is useful for visual learners and those interested in the technical aspects of sound design in Bitwig.
