The Audio Interchange File Format (AIFF) is unique and is often used
on Apple computers It can be little or highly compressed. I can encode
it from other file formats at anywhere between 16-bit,48 kHZ to 16-
bit, 8 kHz(suitable for fair voice reproduction only). If you record
material from web downloads on your computer, then you have to take
the format or formats offered. If you record from CD to the computer
HD , you need to use PCM(a high resolution wav) which is a clone of
the CD without loss of quality The WMP11 will do this. Then, if you
need a compressed format to put up on the web, if it is not the same
as the one you get from a download, you must convert from the wav you
got from CD or the format you got from download to AIFF or whatever
other format you want for the web. The amount of compression you use
will depend on if you want the music to be suitable for dialup as well
as broadband. Uncompressed audio files can be of huge MB size and take
up to hours to download on dialup. Thus there are many compressed
formats such as WMA and AIFF. If you are converting from a highly
compressed mp3 downloaded from the web, then it would be useless to
convert to say 16-bit, 44 Kz AIFF because the sound can be no better
than the original material. I use Easy CD-DA Extractor which will rip
from CD and convert between any of about 16 audio formats on the HD at
a wide range of compression settings for each. This is a pay program,
but there is a free trial version that allows you quite a few days to
try it out. You might find a free program to convert some file types
to AIFF on a Google search.
The QT player(an Apple product) and the real player will both play
AIFF. So will WMP 11, but it may require a codec download to do so.
AIFF does not seem to be very common on the web today, but still quite
a few with Apple computers still like and use it.

Stick to MP3, you can play those anywhere on any platform.
