RightMark Audio Analyzer 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.
Testing is accomplished by playing the test signals and recording them after they pass through the testing chain.
Here are some key features of "RightMark Audio Analyzer":
Spectrum analyzer options are:
· FFT size: variable size of FFT block (in samples) from 128 to 262144
· Resolution: calculation width of each spectrum frequency bin
· Zero padding of audio data before spectrum analysis. Interpolates spectrum and displays it more precisely
· FFT overlap: Overlapping of FFT blocks in time domain. Higher overlapping leads to slightly better spectrum averaging
· FFT window: FFT weighting window selection. Weighting windows affect the level of spectral side-lobes and frequency spreading of spectral main lobes
· Kaiser window beta: Adjusts the shape of Kaiser window. Higher betas lead to better suppression of side lobes (useful when spectrum has high peaks), lower betas lead to slighlty better frequency resolution.
What's New in This Release: [ read full changelog ]
· updated Intel high performance library to IPP 6.0.2;
· accelerated tests IMD + noise (swept sine) and THD + noise (set of tones), these tests work up to 4 times faster now.
