If you have a .wav file, you can easily convert it into MP3 using iTunes. Just open it up using iTunes, then right-click (control click on the Mac) on the song. Choose "Convert Selection to MP3". To figure out where iTunes saved the new MP3, choose File - >Get Info, then look at the Where section at the bottom of the Summary tab.
We are using Amazon's Mechanical Turk (MTurk) platform to do the transcriptions. It's easy to become a transcriptionist,all you have to do is visit mturk.com and sign up for an account - you don't need to have an Amazon account already, as when you sign up one will be created for you.
The next step is for you to take our qualification test. Click on the Qualifications tab at the top of MTurk's website (after logging in) and then find "CastingWords PPT". Click on "Take the Qualification test" and follow the instructions. When your test is accepted you will receive an email letting you know, then you're ready to transcribe!
