Audio Compression Based on Discrete Cosine Transform, Run ...
https://www.ijeit.com/Vol%204/Issue%201/IJEIT1412201407_08.pdf
Abstract— Audio compression addresses the problem of reducing the amount of data required to represent digital audio. It is used for reducing the redundancy by avoiding the unnecessary duplicate data. In the present work a low complexity and efficient coding scheme based on discrete cosine transform (DCT) is proposed.
Compressing Audio with the Discrete Cosine Transform

discrete cosine transform . Specifically, we only retain those coefficients that cumulatively sum to a large part of the signal energy. Here, the signal is an audio file, where only 13% of the DCT coefficients are needed to represent 97% of the signal energy. After compression, the resulting audio is hissy but still legible.

—Audio, compression, quantization, lossy and lossless compression, transforms coding, wavelet transform, DCT coding . I. INTRODUCTION. The sound can be represented by electrical form called Audio. Audio is sound within the range of human hearing. The human ear can recognize frequency ranges from 20 Hz to 20 kHz [3]. There are two reasons make ...
Audio Compression Using DCT and DWT Techniques
https://www.iiste.org/Journals/index.php/JIEA/article/viewFile/12440/12768
Speech compression is performed in the following steps. • Transform technique • Thresholding of transformed coefficients • Quantization • Encoding Transform Technique DCT and DWT methods are used on speech signal. Using DCT, reconstruction of signal can be done very accurately; this property of DCT is used for data compression.

basic ideas behind compression methods, such as mp3. 14.4 Computing the model interpolation coe cients with the DCT Let the vector bcontain one second of sampled audio, and assume that the sampling rate is Nsamples per second (bis of length N). It is tempting to proceed just as in the simple example above by setting up an interpolation model
The Use of FFT and MDCT in MP3 Audio Compression

Overview of MP3 Codec MP3 stands for MPEG-1 Audio Layer III. Created in 1994 by the Moving Pictures Expert Group (MPEG). It is a lossy compression, meaning that not all of the original data is preserved after the compression algorithm is finished. MP3 is also based on ideas from the field of psychoacoustics. The idea is that the the
