Employing Psychoacoustic Model for Digital Audio …
http://umpir.ump.edu.my/id/eprint/7256/1/CD7599.pdf
Digital Audio Watermarking is a technology to hide information in an audio file without the information being audible to the listener, and without affecting in any way the audio quality of the original file. In addition, to increase the quality of watermarked audio, psychoacoustic model will be employed as psychoacoustic model is
Audio watermarking based on psychoacoustic model and ...
https://ieeexplore.ieee.org/document/1442293/
A novel watermarking scheme for audio authentication is proposed in this paper. The scheme combines the psychoacoustic model with wavelet packets to adaptively select the best basis for wavelet packet decomposition such that the subbands are closest to critical bands, given the temporal resolution and computational limit. The proposed method can adaptively …

The proposed psychoacoustic model has direct application to digital perceptual audio coding as well as digital audio watermarking.For digital perceptual audio coding, greater extent of inaudible spectrum provided by the psychoacoustic model results more audio samples to be quantized to zero, leading to a decreased compression bit rate.

In this paper, we present a novel audio spread spectrum watermarking scheme where the watermark is extracted from the original file.By using the psychoacoustic model this technique efficiently takes advantages of masking phenomena in HAS, in order to embed an important amount of watermark data below the masking threshold of the original input ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In this paper, we present a novel audio watermarking scheme using direct sequence spread spectrum (DSSS) method by which we can embed a text message as a watermark into an audio signal imperceptibly. The watermark embedding and extraction are based on the psychoacoustic …

In this paper, a new perception-based watermarking scheme for MPEG-4 scalable to lossless (SLS) audio is proposed. Under the control of the psychoacoustic model, …
Psychoacoustic Model - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/psychoacoustic-model
The psychoacoustic model should use a separate, independent, time-to-frequency mapping instead of the polyphase filter bank because it needs finer frequency resolution for an accurate calculation of the masking thresholds. Both psychoacoustic models use a Fourier transform for this mapping. A standard Hann weighting, applied to the audio data ...
