The Korg MR-1000 portable recorder was announced late last year. Now that it is readily available, I thought I’d discuss some of its unique features. I would also like to point you to an excellent white paper that focuses on unique aspects of digital audio that in the end will help you to understand some of the advanced features included in the MR-1000.

This device is marketed as a recorder that delivers audio at a 1 bit/5.6 MHz super spec. 1-bit recording is one of the latest advancements in digital audio. In the past, this has been adopted for use in the critically acclaimed SACD recording format that provides pristine fidelity. The specified white paper explains in detail how a file format with a 1-bit [reduced] resolution benefits by supporting super-high sample rates. For example, 2.28224 MHz and 5.6448 MHz with the MR-1000.

The supported file formats are: WSD, or Wideband Single-bit Data. This format was created by the One-bit Audio Consortium, and it accommodates all formats of one-bit audio data without limitations in channel number or sample rate. Also, DSF, or DSD Stream File. Korg states that increasing numbers of software titles will support this format in the future, including shareware and freeware. Lastly, multi-bit PCM [BWF] format up to 24bit/192kHz.

Korg’s included AudioGate™ software bundle supports RT conversion and playback of 1-bit files, and can convert 1 bit recordings to familiar AIFF and WAV file formats with user defined bit rates.

The recorder features a 40 gig internal hard drive, combo XLR/1/4″ inputs with preamps, 48v Phantom Power and Limiting. Outputs include dual XLR and unbalanced standard RCA. USB 2.0 connectivity provides high speed media transfer. $1199 US.
