I hope you help some one but it sure the heck confused the heck out of me ? ?
why are you doing the ripping that way.
i just tape from line in and save as a 44 16 hrz pcm wav.
then use which ever wave editor i decide to use that i have. and get rid of the blank space. but i always leave 2 seconds of it on the front and end of the song.
i have found that defragmenting the system messes up the song if there is no blank space on the ends.
( at least on my computer it does.)
but then i have a good loud file i can use with which ever encoder program i have that is working at the time. to encode them to the ogg or mp3.
i do how ever use 128 bits as the lowest amount and 320 bits for the highest on my files. but that is just my tastes.
so for the voice only you can set the lowest for 96 bits and the highest for 128 bits. that will give the encoder the choice and it should not make a file that speeds up that way.
now mind you i said should? which is to mean it can do what it wants. and if you know murpheys law. then that too applys
