The diploma thesis aims on the matter of data hiding (steganography) in audio records. It describes general steganographic principles and aims further on the specifics of data hiding in audio records and also aims on the LSB steganographic technique and suitability of different types of audio records to be used with this technique. The thesis also describes a laboratory exercise focused on steganography in audio records and influence of related aspects on the final audio record which contains secret data. Further, the thesis describes a program that was created especially for the laboratory exercise, from the design, functional as well as implementation-related view. Within the exercise, students will be able to examine how the amount of data to be hidden in the audio record and different ways of data hiding will affect quality of the resulting audio record, and therefore they can become more familiar with the matter of steganography based on the LSB method used in audio records.
