“…Hiding data in audio was investigated in many related papers, e.g., in papers [25][26][27][28][29], the simplest LSB techniques were studied, which, nevertheless, have some advantages. By encoding the LSB of the container, you can hide a very large amount of data.…”

“…In [27], an LSB was proposed with an adaptive number of hiding bits for each audio sample (depending on the size of the hidden data, the size of the covering carrier, and the signal-to-noise ratio). In [28], binary data values were hidden in different places to increase security. In [29], the LSB technique was supplemented with data encryption.…”

Direct spread spectrum technology is traditionally used in radio communication systems with multiple access, for example, in CDMA standards, in global satellite navigation systems, in Wi-Fi network wireless protocols, etc. It ensures high security and reliability of information transfer. In addition, spread spectrum technology provides the transmitted signals with a noise-like appearance, thus hiding the semantic content of the messages. We researched this technology for other implementations. The purpose of our study was to investigate new technologies for hiding data in multimedia files. In particular, we investigated the direct spread spectrum in the context of the development of methods for hiding data in audio containers. We considered various spreading sequences (chip codes) and also explored their use for hiding information in audio files. We conducted experimental studies and estimated the bit error rate (BER) in the recovered data. The article also evaluates the distortion of an audio container by the peak signal-to-noise ratio (PSNR). The results of our research enable us to find out which method of forming chip codes gives a lower BER with equal PSNR. We provide recommendations on the formation of spreading sequences to reliably and safely hide informational messages in audio files.
