<p>Erobbin: </p> <hr /> <div>{{wikipedia|Advanced Audio Coding}}<br /> AAC is a codec designed to provide better compression than [[MP3]]s, and are improved versions of [[MPEG]] audio. AAC actually refers to two similar codecs - MPEG-2 AAC and MPEG-4 AAC.<br /> <br /> AAC has many, many options avaliable and is heavily customisable depending on the desired output.<br /> <br /> It has some advantages over MP3 - it has a greater range of sample frequencies, up to 48 channels and higher coding efficiency. It also has much better handling of frequencies above 16 kHz.<br /> <br /> Depending on the AAC profile and the MP3 encoder, 96 kbit/s AAC can give nearly the same or better perceptional quality as 128 kbit/s MP3.<br /> <br /> MPEG-4 AAC is used by [[iTunes]] and [[iPod]] (see also [http://www.apple.com/mpeg4/aac Apple webpage on AAC]).<br /> <br /> In addition, the Sony PSP (PlayStation Portable) has added AAC support with version 2.0 firmware update, which was released in August 2005 .<br /> <br /> VideoLAN uses the [[FAAC]] (encoder) and [[FAAD]] (decoder) to provide support for AAC audio.<br /> <br /> <br /> ''Some of the text on this page is originally from Wikipedia - see [[wikipedia:AAC|AAC (wikipedia)]]''<br /> <br /> <br /> == Related Links ==<br /> * [[HE-AAC]]<br /> * [http://www.audiocoding.com/ FAAC and FAAD]</div>
