| Abstract | ||
| In this paper we introduce Algorithm to encode and hid un information within high quality digital audio signals . first, The digital audio signals are compression and encoded based on MDCT (Modified Discrete Cosine Transform ) Algorithm , to investigate the masked coefficients of the spectrum that are assumed to be not transmitted in the basic access of broadband network ,the proposed algorithm introduced the most significant concepts in high-quality digital audio encoding or compression in MPEG systems. It involves computers masking curve s(v) of high quality digital audio signals which are experimentally recorded at 32 KHZ sampling rate and quantization of 16 bit/sample to generate blocks , each with size of 1024 samples (32 msec duration). Second the information of text are scanned in file to encoding it into encode text file ,this file are encoded into(0,1)bit using many sub-programes to intered it with audio file codes in the recever the decoding program. | ||
