Mostly everyone rips at 128kbps AAC and it sounds fine to them, either 'cause they don't know any better or because it's a matter of personal choice. I had all my music ripped at 256+kbps (extreme with CDex on my PC) but noticed that it was taking a bit long to update my iPod, transfer music, and it was draining battery life quite a lot. I've recently started to rip my collection again, this time at 128kbps AAC. I've played each clip (128 & 256+kbps) and can't really notice a difference, can't. I've tried this with different types of music. I feel I'm cheating myself by going with the higher kbps if I can't hear the difference, but then I feel I'm not getting the best by ripping at 128kbps. What bitrate does everyone use?
