Efficient Cross-Codec Framing Grid Analysis for Audio Tampering Detection

Document Thumbnail

In this paper we present an audio tampering detection method based on the analysis of discontinuities in the framing grid, caused either by manipulations within the same recording or across recordings even with codec changes. The approach extends state of the art methods for MP3 framing grid detection with respect to efficiency and robustness, and multi-codec support, adding mp3PRO, AAC, and HE-AAC schemes. An evaluation has been carried out using a publicly available dataset. A high performance is reported on both detecting tampering and codecs showing the usefulness of the approach in audio forensics.
