I'm doing some research, and I'm particularly interested in the way bit combinations work in .mp3 and .flac files, can I find common bit combinations in .mp3 files, can I do that with .flac files, can i compare both of them? That kind of stuff.
In the experiment I will be checking 4 types of playlists of different artist and genres. The former will be provided both in .mp3 format and also .flac. The playlists song contents will be analyzed with decoders and the number of bit combination occurrences collected. Due to the number of songs in the playlist and the bitrate of them varying (at least I assume that) I will divide the collected results, firstly, by number of songs and, secondly - bitrate. All off this would be repeated for all the other playlists. The given results should then show if common bit combinations exist and whether .mp3 and .flac formats share them.
Can anyone of you tell me what i can use with processing to find this out or any other alternatives?
