The Recording Industry Association of America (RIAA) today issued a first-ever tally of high-resolution (“hi-res”) music titles available in the U.S.

According to new data compiled by the RIAA from its member labels, more than 33,500 albums representing nearly 400,000 tracks are currently available in Studio Quality formats to stream or download in the U.S. These figures represent a 29% increase over a year ago, as major labels are now releasing some 1,000 albums per month in Studio Quality formats.

Studio Quality is defined as a category encompassing both Hi Res Audio (48khz/20-bit or higher) and the studio production format of 44.1kHz/24-bit audio.

Studio Quality formats are already widely available for some of the U.S.’s most popular music of all time:

• 77% of RIAA’s 100 Highest Gold & Platinum Certified Albums
• 79% of one major streaming service’s Top 100 All-Time Streamed Tracks
• 78% of the SoundScan’s Top 100 Albums of 2018
  68% of one major streaming service’s Top Weekly Tracks
