I have an MP3 file and I would like to see the file's binary.
How can I do this (preferably on a Mac)?

5Questions on Stack Exchange are generally expected to show evidence of own research effort. The first hit for me on Google searching for display file as binary is Display contents of file as binary on Stack Overflow. That question has a few possibilities as answers; do any of them do what you want, and if not, what is it that you want that is different? (For one, this answer appears to do exactly what you want, if you have Ruby available.)– userSep 13, 2013 at 19:19

3@MichaelKjörling in the OP's defense, I'm pretty sure ruby is not installed by default in OSX and it the answer in question will be scary to a non coder. Also consider that the OP is clearly not a coder and your google results depend on your own search history and you need to know what to search for, the OP did not even know that this is called 'binary'.– terdonSep 13, 2013 at 19:35

1@terdon The original question title did use the word 'binary', so there must have been some familiarity with the term. I know Google hit ordering depends on the previous search history, which is why I said it was the top hit for me. I don't know what comes with a default OS X installation, but even so, the Ruby answer isn't the only one there and a simple "I found this, this, and this, but when I tried them all I got was the error message X" would have shown own effort to answer the question before asking (the "research effort" part of the question voting reasons).– userSep 13, 2013 at 19:40

@MichaelKjörling absolutely, the OP could definitely have done more research. I am just pointing out that said research would be harder for the OP than for you or me. Your basic complaint is absolutely valid.– terdonSep 13, 2013 at 19:43

@terdon Ruby 1.8.7 is shipped with OS X, by the way. (Such is Python 2.7.2)– slhckSep 14, 2013 at 9:28

You can use xxd for this. Open a terminal and do this:
xxd -b foo.mp3
This will give you output like the following:
0000000: 01001001 01000100 00110011 00000100 00000000 00000000 ID3...
0000006: 00000000 00000001 00111011 01011001 01010100 01001001 ..;YTI
To get only the 1s and 0s and no spaces or extra information, do this:
xxd -b foo.mp3 | cut -d ' ' -f 2-8 | sed 's/ //g'

Thanks for this but it not working. It say " xxd: Classique.MP3: No such file or directory ". In My folder the file name is Classique.MP3. So i paste " xxd -b Classique.MP3 | cut -d ' ' -f 2-8 | sed 's/ //g' " in terminal. Did i do something wrong Sep 13, 2013 at 20:02

@MaximeArchambault yes, you need to navigate to the correct folder. For example, if you have
Classique.MP3in a folder calledMusiquethat is in your home directory, you will need to usecdto go into that directory. Open the terminal, and typecd /Users/Maxime/Musiqueand then run the command. See here.– terdonSep 13, 2013 at 20:36 -
@MaximeArchambault this really should work, feel free to ping me (post a comment here) and I can try and help you in he chatroom (même en français si tu veux).– terdonSep 14, 2013 at 1:07
