Detect specific sound in MP3 file -- 2

Job ID: 34837221

Budget: $250 – $750 USD

Detect specific sound in a MP3 file. It gives you three options and you have to return an integer of correct answer.

The current challenge for these audio samples is "crowdsound." Any option that has a "crowdsound" is the correct answer. Project must be easy to introduce new sounds!

I prefer this to be coded in .NET/C#, but I'm open to other languages.
