I did some tests. 

I call [O] the original version (the one in SVN)
and [P] the version with your patch

---- classical (Leos_Ianacek - Lasske_tance) - orchestra, with 
-- speed 1.21
no audible artefacts in both 
-- speed 0.83
both versions give a slight tremolo character to the music; 
[P] slighlty (slightly!) more

---- swing (Michael Bouble) - voice and contrabass
-- speed 1.21, 0.83
[O] is quite fine, but
[P] adds a lot of tremolo
--

---- Pop ( Elton John - Your Song ) - voice, piano, guitar, strings
-- speed 1.21
[O]&[P] slight tremolo, almost unheardable
-- speed 0.83
[O] slight tremolo appears in some moments
[P] is possibly a little bit worse
--
(all of the above may be due to a low quality mp3 as well)

I think your patch need some study... unfortunately I do not (yet)
understand the code well enough to look into it.
