For those who care concerning the high-quality sound or transferability of your music archive, you will wish to examine the varied import choices. These help you weigh up the scale of the imported music file in opposition to the constancy of the sound and the diploma to which they will be suitable for a software program and apart from iTunes and the iPod. This text focuses on importing from CD, however, the recommendation applies equally to file you have downloaded or created your self.
To entry the iTunes’ Importing choices, open Preferences (from the iTunes menu on Mac; from the Edit menu on PC) and click on on the Importing tab on the high. The 2 most necessary choices are these in drop downs. They help you select which file format/compression kind to make use of, and the bitrate. For those who’re unsure what a file or bitrate is, learn on.
iTunes at present affords 5 file-format import choices: AAC, MP3, AIFF, Apple Lossless, and WAV. If any of those do not seem in your listing of choices, you are most likely operating an outdated model of iTunes. Obtain and set up the newest model.
Briefly, AAC is finest for each day iPod and laptop use; MP3 is barely worse on the bitrate, however, may be performed on any digital music participant or laptop (and burned onto MP3 CD); Apple Lossless is for constancy fanatics; and AIFF and WAV are solely actually for importing tracks with the intention of burning CDs.
Observe that each one file codecs may be burned to audio CDs and performed again in regular hi-fis – it is solely when sharing precise music records data with non-iTunes or non-iPod tools that compatibility turns into a problem.
The bitrate is the quantity of knowledge that every second of sound is decreased to. The upper the bitrate, the upper the sound high quality, but additionally the extra disk area the observe takes up. The connection between file dimension and bitrate is principally proportional, however the identical is not true of sound high quality, so a 128 Kbps observe takes half as a lot area as the identical observe recorded at 256 Kbps, however, the sound will probably be solely very marginally totally different. Nonetheless, marginal variations are what being a hi-fi obsessive is all about.
The default import setting in latest variations of iTunes, listed as “top quality”, is AAC at 128 Kbps. Most individuals will probably be completely happy with this mix (which is normally mentioned to be roughly equal to MP3 at 160 Kbps), however when you’re into your sound in a severe approach it will not be fairly ok. Notably when you hearken to high-fidelity recordings of acoustic devices, akin to properly recorded classical music, and when you join your iPod or laptop to an honest residence stereo, it’s possible you’ll discover AAC 128 Kbps results in a definite lack of presence and brightness in your favorite recordings. If that’s the case, both go for the Apple Lossless Encoder or follow AAC and up the bitrate. The perfect factor to do is to run a comparative experiment with a suitably well-recorded observe.
