QuantAsylum's QA403 audio analyser has improved noise and distortion performance in comparison to its predecessors and the addition of a flatter response at band edges. This dedicated audio analyser is a driverless USB device; it is ready as soon as you plug it in. The software is free for the QA403, and due to its size, you can easily take it anywhere with you. This audio analyser has a low bandwidth, but a very high 24 bits vertical resolution!
Due to the 8 gain ranges input and 4 gain ranges output, the QA403 delivers consistent performance over wide ranges of in- and output levels. The QA403 supports a REST interface, which makes sure the programmability of this audio analyser is possible in nearly every language. The QA403 is isolated and USB powered, ensuring you are measuring your audio and not some ground loop in the background. If you think a soundcard is too much hassle for too few results, the QA403 is built for you.
