Wav export for itunes bit rate1/6/2023 ![]() ![]() In any case, doubling the bitrate from 128 kbps to 256 kbps won’t make music sound twice as good, because the smaller file already has the most important information. (To compare different bitrates for yourself, click here or here.) All these variations make it difficult to say for certain whether 256 kbps will sound noticeably better than 192, or 160, or 128 kbps. The sound quality of a file at any bitrate also depends on the compression program or “ codec” used to create it some work better than others. Similarly, you’re not going to hear the difference in a car, where tonal quality is already murky, but you might if you’re wearing your noise-canceling headphones. For example, music with delicate timbres-a string quartet, say-might sound noticeably choppy at lower bitrates, whereas compressing an AC/DC song might not be so bad. CDs operate at 1,411 kbps, more than 10 times the rate of MP3s.) But a listener’s ability to distinguish sound quality depends on many factors, like age, hearing ability, and attentiveness, not to mention the style of music and where one listens to it. (The bitrate measures how much digital information gets transmitted every second. Studies ( PDF) have found that as long as you’re using high-quality encoding software, music compressed to a bitrate of 128 kbps or more is “transparent”-in other words, most listeners can’t distinguish it from CD quality. Will people be able to hear the difference? The luxury tracks will cost 30 cents more than the standard downloads. Record label EMI and Apple announced Monday that iTunes will soon offer premium music files, which come without copy protection and have a bitrate of 256 kbps instead of the usual 128 kbps. ![]()
