HRT dSp Digital Sound Processor

High Resolution Technologies (HRT) dSp is a digital Sound processor that provides significantly improved headphone sound quality for smartphones, tablets, and portable devices. The dSp was designed for smartphones, tablets and other portable devices running operating systems such as; Android Lollipop, Chrome OS, Windows, Apple OSX and others. The dSp incorporates proprietary digital Sound processing and conversion along with a high-performance headphone amplifier, all within an extremely portable form factor.

The dSp is designed for those who use their phones, tablets, laptops and other portable devices as their primary listening and viewing platforms and who seek the best-possible headphone or in ear listening experience for music, video, and gaming by providing improved resolution, spatiality, dynamics, and heightened realism.

The HRT dSp is compatible with all audio formats supported by portable devices thanks to its UAC (USB Audio Class) interface. The dSp’s extremely low power consumption allows for extended playing time and with its plug-and-play connectivity, eliminates any complex setups. The dSp supports all audio formats including MP3, AAC, FLAC, PCM, Apple and Windows lossless, along with all streaming audio and video formats, and is firmware-upgradeable to accommodate future updates.

Ideal for use with a wide range of headphones, the dSp draws from HRT’s pioneering R & D in the USB audio accessories category and decades of involvement in high-performance audio. The HRT dSp incorporates high-performance microelectronics and proprietary digital Sound processing software to deliver the very best listening experience possible from any in ears or headphones. With its included cables the dSp can also be used as an outboard digital Sound processor with desktop and notebook computers.

Please note that most i-devices which use the 30-pin connector, can also connect with the dSp but will require the USB iPad Camera Connection Kit (available from Apple stockists), and used in conjunction with the small cable supplied with the dSp.
