Abstract

This paper presents a method for the reconstruction and playback of audio signals represented in a compressed structured format. The primary objective is to implement a universal mechanism for restoring the audio stream in system memory and enabling its real-time playback, regardless of the applied optimization scheme.
The developed software system supports loading compressed CUWAV-format files, converting their contents into a WAV-format audio stream, transmitting the stream to an audio output device, and visualizing the signal as a scalable waveform.
The proposed method allows the system to be used as a universal and extensible module within technical complexes for audio data analysis, monitoring, or archiving.

Keywords:

audio signal, structural compression, optimization, reconstruction, CUWAV format, informational content of sound, lossy compression
