99Designs for Audio (music, voice over, sound effects) Audio Catch is an online marketplace to source custom audio assets (music, sound effects, and voiceovers). Our crowdsourcing model allows customers from advertising agencies to film producers to register their projects and have artists compete for the right to score them. Audio Catch's value to our customers is that artists actually audition for customer projects before being selected to work on them and the budget, deadline, and media rights are all under the customer?s control.
