Tools: ADCTest

ADCTest is an open source software application designed to facilitate performance testing of analog-to-digital converters (ADC) against FADGI’s 2017 Audio Analog-to-Digital Converter Performance Specification and Test Method Guideline (Low Cost).

Developed by AVP in collaboration with Christian Landone, ADCTest is not intended for absolute, high precision testing for the purpose of comparing the performance multiple ADCs, or analyzing nuanced aspects of ADC performance. Instead, its primary purpose is to provide users with a low-cost and simple test tool that will be employed routinely. Routine performance testing, even with lower performance test tools, enables the identification of significant failures, the relative comparison of ADCs in certain cases, and the ability to establish a benchmark for a given ADC to track trends in performance over time.

ADCTest automates the testing protocol for all criteria listed in the FADGI low cost guidelines with a goal towards answering three basic questions:

  • Is my ADC/system failing?
  • How does my calibrated, healthy ADC perform relative to the guideline and other ADCs?
  • Is my ADC/system performing optimally relative to its own specifications?

For more information see the ADCTest introduction and user guide, titled ADC Performance Testing: Low Cost Application, Release 1 (PDF 1.72MB).
