LXSNDTEST is designed for measuring the characteristics of sound cards and A/D
converters of ATmega microcontrollers (for example Arduino), or for testing
circuits connected to a sound card. Tests include: pink noise response,
magnitude/phase response, and distortion, and a search function for finding
the appropriate analysis setup when two different devices are involved in the
LXSNDTEST runs under Linux, using the OSS sound card interface.
