Did some experimenting trying to learn and see the differences Karyn. OMG I was amazed at the quality just on Sound Cloud alone for MP3s. Ive always done Wave 44100/16 files for their uploads.
I tried Mastering with Wave and Mixdown to MP3s @ -
44100/16/192 & 44100/16/320 and I must say "WOW" what a difference.
One thing I have noticed is that the 44100/16/128 files sound rumbly/muddy.
Thanks a bunch for the info everyone!!!
Now I have to retrain my ears again LOL
