Are you interested in measuring the key characteristics of audio circuits but find the professional market's equipment too expensive? Then watch this webinar on affordable audio measurements. Experienced audio circuit designer and Elektor author Alfred Rosenkränzer shows 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.

Use Filters for Audio Measurements

In this webinar, Alfred Rosenkränzer shares some hardware enhancements to help you improve the quality of your measurements. Learn how to use filters to get rid of noise shaping artifacts. Employ a Fliege notch filter to reduce distortion and make good use of low- or band pass filters to clean up generator signals at specific frequencies like 1 kHz. Also, some of the most common questions about audio measurements are answered, including how to handle badly or uncalibrated inputs and outputs and how to prevent the digitizer from creating its own distortion.
