First post, newish user, diligent middle-age, tech-savvy student, recent upgrader from GarageBand. Please be gentle, and I'll buy the wine & dinner. I've dug through the user manual, and searched the net and these forums, but can't find an answer. I'm also aware that because of my inexperience there may be some details I will fail to mention in what follows, so I'll be happy to fill in any blanks...just ask away. I used Zamzar to grab & convert my friend's band's videoâ€”a live recording from the early '80s. It's saved as a .mov file on my desktop. I extracted the stereo track and saved it by itself as a 16/44.1 .aiff file. My goal is to boost the gain, tweak the EQ, and open up the stereo-field space a little. Nothing fancy nor expertâ€”I realize there's only so much shine you can put on a ball of earwax; it just needs to be a little more palatable, and louder. I've dragged the extracted .aiff track into Logic. Channel inserts are basic & native...Gain, Channel EQ, & Spread, that's it. I've tweaked it well enough, and exported as a 16/44.1 .aiff file. Here's where the head scratching begins. Monitoring the enhanced audio in LE8, it sounds decent enough for my needs; the overall volume (very little-to-no clipping), EQ spectrum and stereo spread is much better (to my ears, anyway), but when playing the exported .aiff file in a QT player, there's a marked difference in the EQ, i.e. more mid-to-high freq (say, in the 5-8kHz range). sizzle than I'm hearing in Logic. In A/B'ing the files, I've done the best I can in manually adjusting the output volume from each application, so they are reasonably similar in over all volume. Am I missing some output &/or export considerations in Logic, or is there a reason why QT would interpret the file differently? Many thanks in advance for your participation...I'm loving the learning process!
