Mp3
is a method of compressing audio files in
such a way that the audio quality isn't
compromised too much, yet file storage is
increased. In other words, instead of one
lecture or two exhortations fitting on a
CD, one can convert the audio files to mp3
and store thirty talks
on a single CD. The sound quality is reasonable
to good depending on the quality of the
source, which is the reason for these CD's.
The
original talks came from old tapes, some
dating back to the 70's. The tapes, although
many being the master copies, had faded
sound together with a lot of ambient noise.
To minimise the noise and enhance the speach
an equaliser and normalisation filter was
applied to each file. The files were saved
as wav files which is the format used for
normal audio CD's. The wav files were then
encoded and compressed into mp3 files using
a format that makes them compatible with
mp3 enabled devices. |
The
mp3 file format has worldwide recognition
and acceptance, and has been adopted by
most electronics manufacturers.

| Files
are either stored on a minature hard
drive, solid state memory chips or
removable flash memory sticks.
Flash memory sticks are the preferred
option as they are reliable and more
convenient.
Files have to be transferred from
a computer onto the mp3 player. |
