PROSTUDIOMASTERS is an online music store for high-resolution audio downloads in PCM / AIFF, FLAC and DSD / DSF formats.
High-resolution audio offers the highest-fidelity available, far surpassing the sound quality of traditional CDs. When you listen to music on a CD or tracks purchased via consumer services such as iTunes, you are hearing a low-resolution version of what was actually recorded and mastered in the studio. ProStudioMasters offers the original studio masters — exactly as the artist, producers and sound engineers mastered them — for download, directly to you.
You may need additional software / hardware to take full advantage of the higher 24-bit high-res audio formats, but any music lover that has heard 16-bit vs 24-bit will tell you it's worth it!
