Harman International: Why Clari-Fi Is Better
      #46564 - 06/11/14 09:35 AM

Sprint has partnered with Harman International to offer the HTC One M8 Harman Kardon Edition. Dinesh Paliwal, President and CEO of Harman International recently talked with Sprint on why HARMAN's Clari-Fi is a better technology that restores and "rebuilds" music fidelity lost during audio compression, and why for the first time in a mobile device, Clari-Fi yields richer, deeper and clearer sound quality for compressed digital music (like MP3 downloads or streaming services like Spotify). Here are some of the dialogue between Sprint and Harman:



NP: What exactly is Clari-Fi technology?
Dinesh Paliwal: Clari-Fi is a revolutionary application - for the first time in a mobile device that analyzes digital audio signals in real time and rebuilds them during playback. It does not mask the effects of heavy compression by adding new effects, but instead uses an algorithm to put back what is lost during the compression process. The result? High-quality audio from compressed digital files from any playback source.

Specifically, Clari-Fi removes unwanted added effects like echo and distortion; it restores the crisp detail and clarity of high frequency sounds like cymbals, which can be muddied in compressed sources; it sharpens dynamic sounds like percussion instruments, which can be smeared or dulled by compression; it takes a flat, compressed vocal and brings back the intimacy of the original performance; it rebuilds the stereo image that is often compromised by compression, creating a natural, wide soundstage; and it restores the musical depth that is lost when instruments and vocals are compressed to the same volume.

NP: Tell me, what are the differences that Clari-Fi technology has to offer users?
DP: Unlike other offerings in the market today that focus on using high-resolution file formats on their proprietary device, HARMAN's approach with Clari-Fi is to improve the listening experience for existing sources on all devices across the digital music landscape, seamlessly working with what listeners are already using.

Clari-Fi does not simply add equalization, unnatural reverb or bass boost to try to soften the effects of heavy compression. It does not try to mask the faults of the corrupt signal by adding new effects or blind "sweetening." Instead, it uses scientific probabilities based on the compressed content to put back what was lost. Simply put, the Clari-Fi algorithm doesn't perform gimmicks.

NP: Can you talk about any other features of Clari-Fi that customers might want to know about?
DP: In today's increasingly mobile world, audio formats have morphed from vinyl LP's and CD's to digitized data files downloaded to smartphones and streamed through satellite radio and music services like Spotify. This maximum mobility is made possible by compression processes that create smaller, more portable digitized music files. While compression technology enables easy access to audio content on the go, this process fundamentally alters the music source, discarding up to 90 percent of the audio content captured during the original recording. Clari-Fi was developed to address this deterioration of audio quality.
