Understanding Music File Types with ProSelect
ProSelect supports various types of music files for use in Slideshows and for playing Ambient Music (Pro version). Your computer my have many types of music files.
There are many music subscription services (Apple Music, Amazon Music, Spotify, etc.) available, but in most cases, they don’t let play the music outside of their app, unless the supported application uses a login system to verify the subscription. Even in apps that support this, they don’t allow ultimate control of the individual tracks.
Some services allow downloading of tracks for offline use, but these files are protected using Digital Rights Management (DRM) technology. The purpose of DRM is to prevent unauthorized redistribution of digital media and restrict the ways consumers can copy content they've purchased. From about 2003 to 2009 Apple used DRM in all files sold through iTunes limiting content usage and sharing. Those files used the extension M4P.
In 2009, Apple disbanded DRM while increasing the cost of music. Currently, music purchased through iTunes does not contain DRM limitations. Those files use .M4A extension.
Just because you purchased a file and it is “unprotected”, does not mean you have the right to legally use it in ProSelect. When a song is combined with images and or video, a Synchronization License is required. It doesn’t matter if the show is sold, given away, rendered, delivered on a USB, or just shown in your studio, it’s a violation of the terms under which you purchased the music. Technically, playing popular music in the studio just as background music, is too, a license violation. Think of it like delivering digital files to your customer for social media use and the next thing you know is the image is on brochures and printed as gifts for Grandma.
When using music, it’s always a good idea to respect the rights of content creators just as you would like your work respected.
