+%         audioQualityMeasures(xRef,xTest,fs,options)
+%
+% Inputs:
+%    - xRef: reference signal
+%    - xTest: test signal (to be compared to xRef)
+%    - fs: sampling frequency
+%    - optional parameters [default]:
+%        - options.ENABLE_PEMOQ: flag to use PEMO-Q or not [true]
+%        - options.pemoQExec: name of PEMO-Q executable ['"./PEMO-Q v1.1.2 demo/audioqual_demo.exe"']
+%        - options.PESQExec: name of PESQ executable [''./PESQ/pesq'']
+%        - options.EAQUALExec: name of EAQUAL (PEAQ) executable ['./EAQUAL/eaqual.exe']
+%
+% Note that PEMO-Q and EAQUAL programs are Windows executable and that
+% under unix, they can be used by means of wine (Windows Emulator). One
+% just have to have wine installed.
