Using my precision tools for assessing quality of audio devices and
algorithms I investigated iTunes SRC. The test report is at
http://www.dkab.net/iTunes report.pdf.
As compared to previous MBP built-in audio device report at
http://www.dkab.net/Realtek HDA report.pdf, the new report contains 4
additional analyses and charts. These are: a comparison between test and
response signals, differences between the two, and variations of amplitude
and phase with frequency. MBP built-in device report has also been updated
to contain the new analyses.
I have updated both reports. There are 2 new tests, Intermodulation
Distortion according to ITU-R and to SMPTE test specifications. There also
are some minor cosmetic changes and improvements in the reports.
Thanks/Mikael
