Re: Echo/Spike at the End of Bounced .mp3's

2005-02-16 by msirt@earthlink.net

Thanks GA.  I think the next step for me would be to try a realtime bounce.  Hers's why 
some of your suggestions won't work for me.  Please comment further if I am missing any 
angles:

1) [Adjust start or end times in iTunes]:  Not enough time to do this one-by-one in a 
theatrical performance situation where cues need to be at one's fingertips (unless I'm 
unaware of  the ability for iTunes to save start & end times with each track of a playlist)

2) [Bounce to AIFF's]  Well, bye-bye HD space.  I know, I can convert the AIFF's to mp3's in 
iTunes, but wasn't Logic supposed to be the "all-audio-needs-addressed-within-a-single 
app-solution  (I don't understand why there isn't simple AIFF to mp3 conversion in Logic 
beyond bouncing (or is there))?

3) Re: the nature of the echo:  The echo does not seem to match the opening of the track, 
but rather has characteristics of the audio last heard (end of track) - like a 'hiccup' of the 
songs end (or maybe a 'burp')  Perhaps it's still some sort of buffer problem, but not 
related to cycling back to m 1.

It's comforting to hear that offline bouncing has recognized problems.  I'll just try the 
realtime approach on my next arrangement.

Thanks again,

MS
