A novel high capacity data hiding technique for digital audio is proposed. Imperceptibility of the embedded data is ensured based on the masking property of the human auditory system (HAS). Audio signal is decomposed into subband signals, some of which are selected for embedding data using finite-length impulse response approximations to allpass ...

Genre classification of compressed audio data
2008 IEEE 10th Workshop on Multimedia Signal Processing, 2008This paper deals with the musical genre classification problem, starting from a set of features extracted directly from MPEG-1 layer III compressed audio data. The automatic classification of compressed audio signals into a short hierarchy of musical genres is explored. More specifically, three feature sets for representing timbre, rhythmic content and

Wavelet-based indexing of audio data in audio/multimedia databases
Proceedings International Workshop on Multi-Media Database Management Systems (Cat. No.98TB100249), 2002The phenomenal increase in the amounts of audio (and multimedia) data being generated, processed, and used in several computer applications have necessitated the development of audio (and multimedia) database systems with newer features such as content-based queries and similarity searches to manage and use such data.

Fast Audio Feature Extraction From Compressed Audio Data
IEEE Journal of Selected Topics in Signal Processing, 2011We describe an efficient system, which directly extracts features from compressed audio material. It consists of a time-frequency conversion method and a feature extraction algorithm. The conversion method provides the feature extraction algorithm with a suitable complex spectral representation directly from the compressed domain, and further allows to

Advances in data compression are creating new possibilities for applications combining digital audio and digital video. These applications, such as desktop authoring environments and educational or training programs, often require access to collections of audio/video material. This paper introduces audio/ video, or “AV”, databases and discusses the key

This paper describes the LSB technique for secure data transfer. Secret information can be hidden inside all sorts of cover information: text, images, audio, video and more. Embedding secret messages in digital sound is usually a more difficult process. Varieties of techniques for embedding information in digital audio have been established.

Audio data processing apparatus and audio data distributing apparatus
The Journal of the Acoustical Society of America, 2008A distribution unit 1 divides PCM audio data in plurality of divided data. Each divided data has overlapping sections overlapping with previous and following divided data. An MP3 encoding unit 2 encodes each divided data individually into MP3 data. A filtering process at the time of encoding is executed by using the overlapping sections as similar ...

Joint watermarking of audio-visual data
2001 IEEE Fourth Workshop on Multimedia Signal Processing (Cat. No.01TH8564), 2002Both audio and video watermarking enable copyright protection with owner or customer authentication and the detection of media manipulations. The available watermarking technology concentrates on single media like audio or video. But the typical multimedia stream consists of both video and audio data.

Exposing audio data to the web
Proceedings of the 19th international conference on World wide web, 2010The HTML5 specification introduces the audio and video media elements, and with them the opportunity to change the way media is integrated on the web. The current HTML5 media API provides ways to play and get limited information about audio and video, but no way to programatically access or create such media.

An improved technique for hiding data in audio
2014 Fourth International Conference on Digital Information and Communication Technology and its Applications (DICTAP), 2014This paper presents an improved technique for hiding data in audio. The proposed method modifies the amplitude of the cover audio file to embed the secret message. To increase the security of the proposed scheme, we use a key to adjust the hiding technique.
