What‘s an INDEX?
Some CDs are provided with an index marking system which
divides tracks or discs into smaller segments. This is especially
useful when you want to locate a certain point within a long
track (in classical music for example). The index search function
works only when you use a commercially available indexed discs
(usually indicated on the label).

Sharp roll-off and slow roll-off
Digital filters can be roughly classified into sharp roll-off
types and slow roll-off types, according to their cutoff
characteristics.
Digital filters can be roughly classified into sharp roll-off
types and slow roll-off types, according to their cutoff
characteristics.
Sharp roll-off filters quickly cut off noise over 22.05 kHz
generated during sampling. This is a superior way of
completely reproducing signals below 20 kHz and is the
basic principle behind digital audio.
On the other hand, slow roll-off filters cut off noise
generated during sampling, and are able to hold pre-
ringing and post-ringing (a kind of sound smearing) in
the impulse response signal to a minimum.

Note
The Digital Filter function primarily changes characteristics
outside the audible frequency. They cannot affect changes within
the audible frequency such as those provided by the tone controls
of the amplifier. Therefore, with certain combinations of
hardware and software, there may be no noticeable effect after
switching the filter.
