Abstract—In this paper, a new idea for speech information hiding using fractional cosine transform (FRCT) is proposed. We find in our analysis that the 3rd parameter of FRCT presents property of high frequency, then we put forward two methods for em

In this research paper we discuss the application of the modified discrete cosine transform (MDCT) to audio compression, specifically the MP3 standard. MDCT plays
a very important role in perceptual audio coding. We also discuss all of the four

We numerically investigate the propagation properties of ring Airy Gaussian beams (RAGBs) with cosine modulated optical vortices (CMOV). In comparison to the common RAGBs without any modulation, the dynamic propagation of RAGBs with CMOV exhibits a u
