Seek issue (phase inversion test)

Coming from http://forum.cockos.com/showthread.php?t=31678


Load this project: seek-issue.rar (2.20 MB)


-> playback (from beginning of time selection)

It's not meant to "null out" completely. I just wanted to hear the differences between the original 48kHz 32bit float and the 44.1kHz 16bit dithered file.


So just watch the output levels on the master while playback.

=> Got it? Null out to about -67dB here. Fine.


-> now place the cursor somewhere else on the items while playback or start playback from a different position (not from the beginning of the items)

=> Now the files don't "null out" that good anymore. About 20dB to 30dB increase on the master output if playback isn't started from the beginning of the items. I'm getting values around -26dB then.


Only happens with items with different samplerates in the project. If all items have the same samplerate it doesn't happen.
