Again, I failed to see the logic in adding said features.
Please consider effect for adding a small delay in either channel controlled by a custom tag field. I often find commercial releases with 10-20 ms delay between L-R.
This delay between channels is added intentionally - in purpose of widening stereo basis. Stereo widening effects (like making stereo from mono signal) are always based on adding interchannel delay. So such DSP will be destroying effect rather than sound tuning effect.

If it's a DSP filter, do you have it in your chain? If not, do you have additional processing enabled when converting?
I don't know anything about foo_dsp_effect its inner workings, but why does Pitch Shift (and perhaps other effect-filters too, I don't know) change the duration?Original test sample: 25.500s / 1124550 samplesSoundTouch plugin: 25.488s / 1124032 samplesEffects DSP (Pitch Shift) plugin: 25.479s / 1123640 samplesAvisynth (TimeStretch): 25.500s / 1124550 samples(!)For everyday listening it's no problem, but for encoding I obviously prefer Avisynth at the moment.
Does foo_dsp_effect's de-emphasis recognize dBpoweram's pre-emphasis flag?
The tag "PRE_EMPHASIS" must be used on content which is supported by FB2Ks decode processor services, for this to work. Pre-emphasis can be signified in your media with the values "1" or "0".
