The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs ‘‘radio-   hybrid’’ measurements of air shower radio emission in coincidence with the surface particle detectors   and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be       incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This  goal has been achieved in a natural way by extending the existing Auger Offline software framework         with radio functionality. In this article, we lay out the design, highlights and features of the radio  extension implemented in the Auger Offline framework. Its functionality has achieved a high degree of         sophistication and offers advanced features such as vectorial reconstruction of the electric field,  advanced signal processing algorithms, a transparent and efficient handling of FFTs, a very detailed           simulation of detector effects, and the read-in of multiple data formats including data from various radio simulation codes. The source code of this radio functionality can be made available to interestedparties on request.
