Sorry if this is a Fool Question...
for me, i alway use APE , MPC , OGG for backup my CD's into my HDD
this is not problem with APE ( bcoz it's lossless :-) )
Mr. BIG - Actual Size -02- Wake Up
Original Length ( Differant Samples ) ( Differant Times )
9827244 (+- 0) (+- 0:00.000)
MPC - Q8
9827136 (- 108) (- 0:00.003)
OGG - Q8
9827244 (+- 0) (+- 0:00.000) *i remember i have ever see this format have differant samples length... ( for this time i don't have long length song - -" sorry )
MP3 (Lame -Standard) 207 kbps (Average)
9830016 (+ 2772) (+ 0:00.062)
Look like with OGG , APE is best choice for me to keep samples length...
before i think about this my plan is convert my APE(s) to MPC but all my APE(s) have Trimed Digital Silence.... maybe i must add some Silence Sample to my APE(s) before encode them to MPC ?....
or my problem is Decoder ?
Thank you for all Reply.
(and sorry if this is fool question , my bad at english = =" )
At last i still stick with APE - -" hur hur....
Edit: added time for look easy - -"
Full Version: How to keep Original Song Length on Lossy Format ?
I just encoded a few files with MPC and decoded them. All had exact input and output lengths.
What version MPC encoder and decoder are you using?

it's v1.15r Alpha.
This is actually one of the major drawbacks, in my mind, to mp3 and wma (though wma supposedly has fixed the extra-samples in lead-in and lead-out thing in the new version 9 - but never mind b/c few "serious" people use it).
Anyway, there are ways to encode mp3 without changing the sample length (much, anyway), such as the gapless encoding option offered by speek's Lame frontend "all2lame". I don't know exactly what it's doing, but it seems to be something with the file header, b/c winamp can't accurately judge the time-length of files encoded as such, nor does it give correct read on the frame # or file encoding (i.e., it'll say 160 kbps or 96 kbps when I actually encoded at ABR 145 (so it should say something like VBR 142.4 kbps). What I generally do with mp3 is to encode normally (without the gapless option, even when I'm doing live concert or Pink Floyd or something that is gapless in the original) and trip any extra frames of silence off the end with mp3trim. But Vorbis is nicer (and mpc as well) for keeping the exact filelength, down to a single sample.

How do you decode the files ? Winamp + disk writer may cut the end of the last track of the playlist.
