Unified filter bank for performing signal conversions

A method for implementing a unified filter bank that performs signal conversions, comprising:

• receiving signal conversion commands and accompanying data in relation to multiple types of compressed audio bitstreams;
• performing at least one transform as part of signal conversion for the multiple types of compressed audio bitstreams;
• performing complementary processing as part of the signal conversion for the multiple types of compressed audio bitstreams;
• and
• controlling the configuration of a reconfigurable transform component that performs the at least one transform, the configuration of complementary modules that perform the complementary processing, and the order in which the complementary modules are connected and executed.
