Technical Questions

FAQ about nerdy stuff
What should I name my .wav file? What about tagging?
Nowadays that’s done in Distribution. We live in a glorious post-CD world where distribution companies like Distrokid, Tunecore, and more will put in your music on a hundred sources at once. It’s their job to make sure all the titles, accreditations, track order, and more all show up correctly on every platform and in every file type.
What are Apple Digital Masters (ADM) and why do I want it?
Apple Digital Masters, previously known as Mastered for iTunes (MFiT), is a fantastic future-proofing mastering standard pioneered by Apple to ensure all music is archived at maximum quality. It also is designed that your music will play through internet radio and lossy formats without clipping. MFiT certified masters also get preferential placement in the iTunes store. Alex Santilli is an Apple Certified mastering engineer and all music mastered here will benefit from the technical advances of ADM, but only 24-bit ADM masters are ADM certified.
Doesn’t every song need to as loud as possible?
Thankfully, the loudness wars are over. Every internet and terrestrial radio will make sure all songs are played back at the same loudness regardless of how ‘loud’ it is mastered. Making songs too loud will only ensure that they don’t ‘hit’ when being played on radio. A master of reasonable loudness will sound better on radio than a loud master.
