In recent years, the music market has changed from CD to digital distribution. MP3 is the representative compressed sound source of online music distribution services. MP3 formatted quality is inferior to uncompressed sound sources. Because MP3 formatted quality has less information. This manuscript describes the difference between compressed sound sources and uncompressed sound source by use of EEG analysis. This time, we prepared two types of different solo sources of binaural recorded instruments, presented by headphones, and let multiple subjects listen to compressed sound sources and uncompressed sound sources with different bit rates. At this time, we analyzed how the brain waves derived from subjects differed using wavelet transformation and reported on it as a result of examination.
