I know from experience that if I have a high quality jpg that I can convert it to a tif and back to a low res jpg without really suffering any discernable artifact intrusion.
I'm wondering if the same holds true for aif/mp3.
You see I've got a bunch of low quality (recorded) talks, lots of boominess and background rumble. Some are in aiff but some are in high quality mp3, (that's high quality but crap recording).
If the analogy holds true it would suggest that I could convert the mp3 to aiff by importing into garageband (or audacity) and try to improve the sound then export an aiff and try to crush it down to a small mp3.
I know it's better to leave it as an aiff all the way through till the end but i'm wondering if pulling a 160kbps mp3 into GB then converting to a 32kbps mp3 is going to be that much worse than if it was an aiff to begin with yet badly recorded.
I'm not certain that I've made myself clear but I hope so
