Free audio signals software for windows

RightMark Audio Analyzer 6.2.1 is designed for you to test an audio performance of your sound card. Frequency response, THD, dynamic range, noise level, stereo crosstalk tests. User friendly interface and comprehensive manual. The program is already used by many internet sites to make reviews of sound cards.

RMAA suite is designed for testing quality of analog and digital paths of any audio devices, be it a sound card, an MP3 player, a consumer CD/DVD player or an acoustic set. The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. A more common mark is also provided for those unfamiliar with measured technical parameters.

A new version is the result of two years of development by best experts in digital audio. RMAA 6.0 raises the bar of comfort and functionality for spectrum analyzers.
