Transform your recorded music into crisp and clarion tracks with today’s melody-tuning side deal: for $15, you get professional sound mastering for one song at Diamondisc Audio (a $30 value). Up to 10 Groupons may be used to master 10 separate songs.

Thanks to 14 years of sound-mastering experience, the staff at Diamondisc Audio knows how to skillfully imbue recorded music with sparkling alacrity while ensuring that each track booms with attention-grabbing verve. Each Package D offers premier 32-bit mastering that sheds glitches, static, pops, and tics from upbeat ditties and shredding anthems while also keeping songs meticulously EQ’d by adjusting highs, mids, and low frequencies before compression and normalization. Tube compression and multiband limiting infuse jams with eyebrow-raising warmth, punch, and clarity—and CDs will also be mastered by removing noise between songs, fixing gaps, and cleaning up fades. Additionally, aspiring musicians can rest easy knowing their precious tunes are in the hands of chief engineer Doug Diamond, who has worked with notable recording artists such as Stevie Nicks, Meatloaf, The B-52s, and Michael Jackson. Clean up muddled tracks and showcase professionally polished harmonies with today’s sound-bending side deal.
