&lt;div&gt;''Part of [[Understanding AAC]]''&lt;br /&gt;
&lt;br /&gt;
This page describes the process of reconstructing [[PCM]] data based on the [[Decoding AAC CPE|decoded CPE parameters]] in an AAC bitstream. For the moment, this description focuses on what is necessary to reconstruct low complexity (LC) profile data.&lt;br /&gt;
