That’s up to you. Most clients want a digital file that can be downloaded from a web page or FTP site. SoundTrax uses Dropbox to deliver client files quickly & securely over the web. We prefer to give you an uncompressed .wav or .aif file, but we can also output mp3 and other “lossy” formats if needed. We can also deliver your project on a CD- or DVD-ROM, or as a master CD-audio disk. For video, we usually deliver a digital audio file that you can easily drop into your editor. We can also output your project in the same Quicktime format as a .mov file.
