I have a couple of hi-res files (24/44) that seems to have audio volume drop-outs at certain points, as if it is an over-reacting dynamic clip prevention. If I try the same file in Foobar 2000, I do not get the sound drop-outs. Dithering is turned on, ReplayGain is on "album", and I tried it both with and without clipping prevention, but both times I got the drop-outs.

The file is too large to attach here, but I can provide it via other means. They are tracks from Steven Wilson - The Raven That Refused to Sing. I resampled and dithered the official 24/96 release to 24/44 using iZotope RX 3 Advanced. I can provide both resampler and dither settings if desired, or I can just provide the effected tracks (title track, "The Watchmaker", both near the end), or the files themselves.
This task depends upon

Reason for closing:  Out of Date
Additional comments about closing:  No test file or response, but probably the issue is just too slow of a CPU for (unspecified) format and DSP effects selected.

I'd suggest linking a part of the file that has the problem, or else making a shorter sample that has it. Otherwise its basically impossible to tell you anything, I don't even know what format you're using. Could be anything from your CPU being too slow to decode the file to a bug in one of the decoders.
