The larger number means less compression and, in theory, better sound. To find out how compression levels (as opposed to formats) affected audio, I also saved. wma (Microsoft’s format), and the old standard, generic. m4a (which uses aac compression and is what you get from iTunes). To test music formats, I saved the clips with 128kbps compression in the three most popular formats. The other came from Joan Osborne’s cover of Bob Dylan’s “Man in the Long Black Coat.” One came from the first movement of Tchaikovsky’s sixth symphony, performed by the London Symphony Orchestra, with Igor Markevitch conducting. I ripped two 30-second clips from CDs for tests. Besides, this type of test is inherently subjective people respond to what they like. I only used two recordings and four jurors-hardly a scientific sample size. You should consider my results to be anecdotal, not definitive. A jury of musicians rated various compressed samples on how closely they resembled the original. To get a less biased judgment, I set up blind audio quality tests. They know they’re listening to a highly compressed song, so they blame the compression for every real or imagined flaw. Many people say they can hear the difference between music compressed at different levels, but their experiences could be shaped by their expectations. wma files, compressed to 160kbps, the whole album is less than 64MB, leaving room for 127 similarly-squeezed albums. You couldn’t fit 15 albums of equal length on an 8GB iPod Touch. wav files, they would take up 556MB of space. For instance, if you ripped Dire Straits’ album Brothers in Arms to your hard drive as uncompressed.
