How would you go about building a Music Recognition app

I am trying to build an app to recognize a song based on a user input. I would like to know how I should go about building this app. I have an idea that I must have the songs already in a source such as a database or cloud to compare them but what and how should I make the comparison isn't plain. I have seen apps for iPhones and other smart phones have this feature and even some websites but I am at a loss to how they actually manage to do this. Any help is appreciated.

Solution 1

What sort of user input? Do they whistle, hum or attempt to sing into a microphone? Do they type in part of the lyrics?

If you do not explain clearly no one will be able to help.

I want a user to input an file ie mp3 , mp4 etc

If what you want to do is get the information about the mp3 e.g. Artist, track length, cover art etc then that is 'relatively' easy. There are online databases with all that information although I do not know if they are free for sure but suspect that they are. If you have a CD Ripper program it will almost certainly have in it's settings somewhere a list of the databases to search. Have a look at the list and then research those sites.

If you want to actually compare the audio/music then IMO it is almost impossible. There have been lots of questions about it here and I have not seen one answered completely. I may have missed one that was though so you should search this forum using compare audio files as the search phrase and read through the threads.

I would also want to know about the copy right information. If the track is named differently or miss spelled this would be hard to catch or match and thanks for the prompt response

I cannot help with Copyright issues except to say that it is important and that it is good that you are considering this aspect.

As for the rest, if you download the Header and trailer information/specification from here --> http://www.wotsit.org/list.asp?page=15&fc=0&search=&al= you will see that 'good' mp3s have a trailer record of 128 bytes which contains that stuff and I don't think just renaming the file would cause that to change. (you can also get information, with a bit of explanation, here -->http://www.mpgedit.org/mpgedit/mpeg_format/mpeghdr.htm.

Good luck.

Is there a know way to read this with asp.net or does it have to be a 3rd party library

Henry Minute 6-Apr-11 12:09pm

You could write your own but I suspect that there are several 3rd party libraries out there if you google around for something like c# read mp3 header trailer (substitute vb for c# if desired)
