Origins and expansion
The company was privately founded by David and Norman Chesky of the audiophile recording company Chesky Records, and is based in New York, NY. The service was launched on March 21, 2008, initially offering only CD-quality 44.1khz audio files in AIFF format from a small offering of independent record labels, including audiophile record company catalogs from Chesky Records, Reference Recordings, 2L, and blues labels like Alligator Records. Shortly after its initial launch, HDtracks began offering higher sample and bit rate recordings such as 96 kHz/24bit, 192 kHz/24bit and other higher resolution than CD sound files with a focus on jazz, classical music, adult-oriented rock, and historic recordings targeting adult consumers looking for an alternative to lesser-quality compressed mp3 files.
