RightMark Audio Analyzer
RightMark Audio Analyzer is a handy piece of software that can perform quality analysis for any audio equipment connected to your computer., whether it is the sound card, the headphones, your CD/DVD player or the speaker system.
In order to test the audio devices, the program uses frequency analysis algorithms. It can perform both playback and recording tests for the PC sound card or other audio equipment, thus detecting possible output distortions.
All the playback or recording devices are automatically detected by RightMark Audio Analyzer and displayed in a drop-down menu, allowing you to choose the item you want to test, as well as the sampling modes (rate and capacity).
The main interface bundles all the configuration options and the test lists. Before playing the test signals, you can choose to normalize them, in order to eliminate different signal levels.
There are several tests that you can perform. Frequency response and total harmonic distortion allow speaker system testing, but you also have tests for your system subwoofer and other devices. Thus, you can run an intermodulation distortion test, crosstalk measurement (suitable for testing the stereo quality of mobile phones) or the swept frequencies test.
After all testing is complete you can view the values of all the selected parameters in the 'Test results' window. One advantage is that you can load test results for multiple devices, which allows you to compare them. Furthermore, each set of results can be viewed and analyzed using spectral graphs.
The program also features a FFT frequency analyzer, which you can use to view the spectrum of a WAV file at a linear scale.
RightMark Audio Analyzer is capable of analyzing, playing and recording test signals to determine determine the signal quality of any device. The tests it performs ensure that you get the best audio signal from any audio equipment.
