Korg MR-1 review: Korg MR-1

Once you get past Korg's DSD recording feature, there's little else the MR-1 can brag about as a portable audio recorder. The Korg MR-1's built-in battery holds a measly 2-hour charge, the internal hard drive caps out at 20GB, the audio input jacks have to be adapted for most microphones or line-input cables, the included microphone feels like an afterthought, and the power adapter is larger than the product it's powering.

However, the Korg MR-1 does have excellent recording format support, supporting several proprietary high-resolution files such as DFF, DSF, and WSD, as well as common file types such as MP3 (192Kbps/44.1kHz) and WAV (up to 24-bit/192Khz). Once your recordings have been transferred to your computer, you can use Korg's included Audiogate audio software (Mac/PC) for converting the files into your desired final format.


The Korg Audiogate software is basic and offers little in the way of editing. It's necessary, however, if you want to convert recordings made in the DFF, DSF, or WSD file format, into more useful WAV and MP3 files.

Performance
It's hard to find fault with Korg's unprecedented recording quality and file format resolution, but the MR-1's poor suitability as a truly mobile device makes it tough to recommend. Rated at 2.5 hours of battery life while recording WAV files, or just 2 hours for DSD file recording, the Korg MR-1 just isn't cut out for the demands of mobile recording. To be fair, running an audio chip at the unprecedented 2.82MHz required to handle DSD audio must require some serious power--but if you can't take it away from a wall socket for more than 2 to 4 hours, then its usefulness is limited as a mobile solution. As of January 2008, Korg is now shipping the MR-1 with an extra external battery pack that doubles the device's recording time. Unfortunately, the external battery pack adds awkward bulk and still places the MR-1's battery life short of the 12 hours boasted by the Sony PCM-D50. To make matters worse, we also found the Korg MR-1's charge time to be painfully long. During our unofficial preliminary testing, it took the Korg MR-1 between 3 to 4 hours to reach full charge using the included power adapter.

The small lavalier condenser microphone included with the Korg MR-1 barely taps into the device's sonic potential. Recordings made using the microphone in both indoor and outdoor situations were riddled with microphonic artifacts caused by movement of the cable, or transference from the surface the microphone was placed on (using the included stand). If you're determined to use the Korg MR-1 for nature or concert recording, expect to shell out some money for a better microphone.

Final thoughts
Beyond Korg's innovative DSD recording feature, there's no reason to choose the Korg MR-1 over its less-expensive competition. To Korg's credit, the MR-1 is the least expensive way to capture and transfer recordings at a pristine 1-bit, 2.8MHz resolution; however, audio professionals will likely prefer the rugged construction and standard inputs of the Korg MR-1000.
