– Upload uncompressed degraded (under test) audio file in .wav format;<br>
– Select what file(s) to test against what file(s) from available
uploads;<br>
– Check default set of AQuA parameters and applies changes by turning
corresponding switches on/off or providing numerical values
for where appropriate;<br>
– System invokes AQuA engine and makes on the fly test by comparing two
audio files;<br>
– After test execution service creates correspondent records and test
report files that one can download and listen to them (via embedded Jscript
player with a waveform view), parameters used for the test,</span></p>
