2005年我在圣彼得堡参加一个音乐节用了一款不错的携带式录音机，当时用的是Korg MR-1那款，录音效果很好（是否好这时完全取决于所用的麦克风和，麦克风摆放位置以及录音现场的自然音响环境）。不但录音效果好，而且重放一样好。现在大家听Ipod等媒体播放器或者在电脑上听网上下载（即便下载到很高格式的录音母带），你的播放器或电脑声卡上的AD转换芯片首先就将再好录音的音源破坏和降级了，出来的自然是严重变质的声音。Korg DSD录音机是设计来作为专业录音用的，即便他被专业录音师认为不够专业，但是对于我们这些聆听者而言就是一个不错的发烧级媒体录放机，出门可以作为随身听，听从任何音源上转录来的高品质声音，回家接在解码器或者就用本机的模拟输出，都可以播放出上等的声音，不信就试试！正如，在电脑上看电子版的小说永远代替不了手捧一本印刷和封面设计精美的纸质小说。再好的媒体播放器也许永远代替不了听LP和听CD的感觉。今后幸存的CD可能是录音和制作精美的，比方说SACD/XRCD混合激光唱片。历史录音本身就无法讲究录音效果，还有廉价唱片和盗版唱片可能就会被网上在线听或者下载到媒体播放器上播放。这是我个人的猜想。
Korg-MR1000的介绍
The future is now. Wow!
This super-portable professional mobile recorder boasts extreme high fidelity 1-bit recording technology, delivering a mind-boggling 1-bit/5.6 MHz that literally doubles industry DSD recording quality standards. It's sure to become the gold standard of professionals who want to record and archive their final mixes in the studio, while its compact size makes it perfect for location recording, podcasting, live music and just about every other application this new century will demand.
1-bit recording is the newest wonder of the audio world and has been adopted for use in the SACD recording format. Its uncompromising fidelity, low noise floor, extended dynamic range, lifelike imaging and analog quality depth have been praised by top experts. Another benefit of the 1-bit format is that it can be converted to any other bit depth and sample rate without error or degradation. After recording and editing all your tracks in the DAW/hardware system of your choice, you can mix directly, or via an analog summing mixer, to the MR-1000. This gives you the superb fidelity of high-rate 1-bit technology, which preserves all the transients, nuances, and “air” from the original recording. It also comes bundled with powerful AudioGate software that lets you convert your 1-bit recordings and mixes into all of today's audio formats without degradation. Best of all, by archiving your data/mix in this new double-speed 1-bit format you're ready for the future. Even as playback systems and standards continue to evolve, you'll be a step or two ahead of them. It supports multiple recording formats including DSDIFF, DSF and WSD 1-Bit formats as well as multi-bit PCM format (BWF) with resolutions up to 24-bit/192 kHz. Its 40GB internal hard drive gives you a up to six hours of recording at the highest audio quality (1-bit 5.6448 MHz stereo), or approximately sixty hours at CD quality (16-bit 44.1 kHz). It sports combination XLR/ 1/4" input connectors with top quality microphone preamps, phantom power and built-in limiting, and offers both XLR and RCA outputs for maximum flexibility.
