In this episode of Sound Design Live I talk with sound engineer, producer, and trainer on network technology and Lake processing, Bodo Felusch. We discuss practicing using your audio analyzer at home without a PA, identifying a comb filter, and the importance of understanding the network your audio is traveling over.

I ask:

  • What is your favorite test track for checking crossover alignment between main and sub?
  • How did you get your first job in audio?
  • In your exercises for FFT (The Ultimate System Tuning Homework) you suggest that I shouldn’t be wasting my client’s time learning how to use my audio analyzer in the field, but this is one of the biggest challenges with learning system tuning, how do I practice at home when I don’t have a PA?
    • One of the very first things I learned from your FFT self-guided homework is that I can find the frequency and the time period of a comb filter by 1 / Frequency of first dip / 2. So if I find the first dip at 50Hz, that would be (1 / 50Hz / 2 = 10ms. How does this information help me in my sound system setup?
  • On coherence you say, “Now you don’t have friends in catering because your measurement signal is too loud.” How loud does my measurement signal need to be? Or how quiet can I make it so that I don’t loose friends in catering?
  • What is a Lake Controller? What is one of the most common mistakes people make who are new to Lake Controllers?
  • Why do I need to understand audio networks? Isn’t Dante and AVB just another fad that will go away in a few years?

Technology fails and you need to make decisions, fast, and fix it. Without knowing what is going on in the network, you will fail.

Notes

  1. All music in this podcast by Bodo Felusch.
  2. Hardware: Lake processor
  3. CRE = Chief Redundant Engineer
  4. Books: Factfullness from Hans Rosling
  5. Gapminder Test
  6. Quotes
    1. Now you don’t have friends in catering because your measurement signal is too loud.
    2. Do your homework at home.
    3. If you measure 10dB above the noise floor you will have a 3dB ripple. If you measure 20dB above you will have a 1dB ripple.
    4. Once you transport your show relevant signals over IT, and only IT, it makes sense that you know how a network works. Without knowing what is going on with the network, you will fail.
    5. We could both be replaced in an hour, and that’s good. There is no superstar in audio.
