سنعرض في هذا البحث طريقة جديدة لتضمين العلامة المائية الرقمية في ملفات الصوت ذو النوع wav باستخدام تحويل الموجة المتقطع مع طريقة استخراجها. و سندرس جودة و متانة هذه الطريقة ضد الهجمات الأكثر شيوعاً كفلاتر تمرير الترددات المرتفعة و المنخفضة, إضافة ضجيج غوص الأبيض, إعادة التكميم, و مقاومة الضغط من النوع MP3 و ذلك من خلال قياس معدل طاقة الإشارة إلى الضجيج (PSNR) و معامل الارتباط (NC).
In this paper, we propose a new method to embed digital watermarking in audio files, using Discrete Wavelet Transform (DWT) and the way to extract the watermark data. The method efficiency is measured using Peak Signal –to-Noise Ratio (PSNR) , Normalized Correlation Coefficient (NC). The advantage of our method is the robustness against several attacks and compression.

A digital watermark is a signal that is embedded into digital data
(text, image, audio, video) in a manner that allows it to be extracted
later. This is done by embedding a pattern which contains the
author's data into the digital data.
In this r
esearch, we propose a comparison between three types of
transformations for embedding a watermark in the frequency
domain into digital images in an efficient and secure method that
allows the watermarking any type of digital images with good
perceptibility.
Epilepsy is a chronic neurological disorder that occurs in the brain،
and affects approximately 2% of people around the world، where
epilepsy patients face a lot of difficulties in everyday life due to the
occurrence of seizures. Electroencephalog
ram (EEG) is used in
the automated detection of epileptic seizures، which has
Characteristics of non-linear and non-stationary. In this research،
we conducted automated detection of the seizures from the scalp
EEG signals using a Level 5 Discrete Wavelet Transforms DWT to
analyze the signal and extracting statistical features (maximum،
minimum، mean، average ، standard deviation، the ratio between
the mean values) and Categorizing using artificial neural networks
ANN for classification. The suggested detection method has
89.85% detection accuracy with 90.60% sensitivity ، and 89.1%
specificity.
The sound is an essential component of multimedia, and due to the needto be used in
many life applications such as television broadcasting andcommunication programs, so it
was necessary for the existence of audio signal processing techniquessuch as
compressing,
improving, and noisereduction.
Data compression process aims to reduce the bit rate used, by doing encoding
information using fewer bits than the original representation for transmitting and storing.
By this process,the unnecessary information is determined and removed, that means it
gives the compressed information for useable compression, which we need as a
fundamental, not the minutest details.
This research aims to study how to process sound and musical signal. It's a process
that consists of a wide range of applications like coding and digital compression for the
effective transport and storage on mobile phones and portable music players, modeling and
reproduction of the sound of musical instruments and music halls and the harmonics of
digital music, editing digital music, and classification of music content, and other things.
Abstract We introduce Generative Spoken Language Modeling, the task of learning the acoustic and linguistic characteristics of a language from raw audio (no text, no labels), and a set of metrics to automatically evaluate the learned representations
at acoustic and linguistic levels for both encoding and generation. We set up baseline systems consisting of a discrete speech encoder (returning pseudo-text units), a generative language model (trained on pseudo- text), and a speech decoder (generating a waveform from pseudo-text) all trained without supervision and validate the proposed metrics with human evaluation. Across 3 speech encoders (CPC, wav2vec 2.0, HuBERT), we find that the number of discrete units (50, 100, or 200) matters in a task-dependent and encoder- dependent way, and that some combinations approach text-based systems.1
This research aimed to study the possibility of using a digital
camera in estimating soil color and compare it with Munsell soil
color chart, and then study the correlation between soil color as
important classification properties and soil content of organic
matter, soil content of total carbonate and soil Texture.
