Filtering applied to an audio signal before storage or transmission to
improve the signal-to-noise ratio at high frequencies.
An embodiment of an encoding process.
Entropy, the average amount of information represented by a symbol in
a message, is a function of the model used to produce that message and
can be reduced by increasing the complexity of the model so that it better
reflects the actual distribution of source symbols in the original message.
Entropy is a measure of the information contained
in message, it's the lower bound for compression.
Variable length lossless coding of the digital representation of a signal
to reduce statistical redundancy.
EFM (Eight to Fourteen Modulation)
EFM is a storing scheme developed by Philips and Sony. It provides redondance
of data in order to increase reliability. It is used in DVD.
