On my system there is a problem with low-frequency background ‘beats’ on Realtrack 2336 (Viola, Background, Pop Ev 085). It takes the form of a beat and then a double-beat - in time - although not on every note played. It can be heard on various of the ‘raw’ viola audio tracks relating in the Realtracks folder. In my case vla001.flac and many others in the same folder show the effect clearly. I wonder if it is caused by foot-tapping?

After upgrading to ‘Audiophile’ I no longer have the .wma versions to check if it is present on those.

Wonder if anyone could check their files, please, to see if effect is noticeable, or if I have a low frequency ‘quirk’ with mine?
