| Abstract | With the booming of smartphone and high-speed wireless networks in recent years, audio streaming and sharing become convenient and inexpensive, so that digital media is gradually replacing physical media. This trend has also led to more attacks to digital audio and its application. MP3 double compression, achieved by decompressing and recompressing audio to a different compression ratio, is a typical manipulation of audio for malicious purposes. In this paper, we propose an approach for detecting both up-transcoded and down-transcoded MP3 audio files and revealing the real compression quality based on statistical patterns extracted from quantized MDCT coefficients and their derivatives. To minimize the false prediction caused by individual characteristics of diversified audio clips, we generated reference audio signals by recompressing and calibrating the audio, and measured the differences between signal-based and reference-based features. Support vector machines and dynamic evolving neural-fuzzy inference systems were applied for binary and multi-class classifications. The experimental results show that our approach effectively detects MP3 double compression and exposes the audio processing history for digital forensics. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
