Robust Audio Watermarking for Copyright Protection

This paper introduces an audio watermark encoding system that is robust to commonly used audio compression techniques such as MP3, AAC and OGG. The watermark is embedded by applying MPEG Layer 2 Model 2 psychoacoustic masking in an iterative way. The decoding is performed by using a correlation based blind decoding algorithm supported via a wavelet denoising module. Unlike most of the existing ...

Adaptive Audio Watermarking Scheme for Copyright Protection

Audio Digital Watermarking for Copyright Protection

When dealing with copyright protection for audio, watermarking can be considered to label the digital medium, by hiding information into the data. To make the watermark imperceptible and robust against some signal processing, we propose in this paper a new method based on frequential substitution, for which the bit error rate is lower than those obtained with existing methods. For such a purpos...

A Novel Audio Aggregation Watermarking Algorithm Based on Copyright Protection

A novel algorithm of audio aggregation watermarking was proposed in this paper for copyright protection. The algorithm not only protects copyright of a single audio in audio aggregation but also protects copyright of the whole audio aggregation. The experimental results showed the watermark of aggregate audio can resist to some attacks, for example, deleting audio, and substituting audio; at th...

Generating Sheet Music From Audio Files

This paper describes a method for using supervised learning to generate sheet music from audio files of single instrument melodies. Support Vector Machines were used to detect the presence of up to 88 notes with one-versus-all classification. We also outline preliminary steps toward transcribing a whole melody by using a sliding window to detect note changes in an audio sample.
