Agenda

About this themed webinar:

Are you interested in measuring the key characteristics of audio circuits but find the professional market's equipment too expensive? Then join our upcoming webinar on Affordable Audio Measurements! Alfred Rosenkränzer will show you how to measure audio circuits without breaking the bank, using free or low-cost audio measurement software and an external or internal USB sound card.

In this webinar, we'll share some hardware enhancements to help you improve the quality of your measurements. Learn how to use filters to get rid of noise shaping artifacts, Fliege notch filter to reduce distortion, and low or bandpass filters to clean up the generator signal at a specific frequency like 1 kHz. We'll also answer some of the most common questions about audio measurements, including how to handle uncalibrated inputs and outputs and how to prevent the digitizer from creating its own distortion.

Highlights:

Introduction to affordable audio measurement solutions
Hardware enhancements to improve the quality of your measurements
Tips and tricks for handling uncalibrated inputs and outputs
How to prevent the digitizer from creating its own distortion

Questions to be answered:

How can you handle uncalibrated outputs?
How do you handle uncalibrated inputs?
How can you get rid of noise shaping artifacts of the DAC?
How can you clean up the generator output for a specific test frequency?
How can you prevent the digitizer from creating its own distortion?

Giveaway:

As a bonus, five lucky attendees will have a chance to win an Elektor Audio Collection (USB Stick). This USB stick contains over 220 selected audio circuits published in Elektor between 1994 and 2009, providing a comprehensive collection of audio designs for home construction. Don't miss this opportunity to improve your audio measurements!
