From the Manufacturer
The latest addition to Sony's family of portable audio recorders, the PCM-D50 recorder adopts many of its features and style from the highly acclaimed PCM-D1 model, including rugged construction and cool design. It's the ideal choice for making live musical, nature sound and field recordings. The PCM-D50 is a 96 kHz/24-bit recorder fitted with two-position (X-Y or Wide) stereo microphones, 4 GB of internal flashmemory and a Memory Stick Pro-HG Duo™ slot for additional storage. Operating on four AA alkaline batteries, it provides 14 hours of record operation at 44.1kHz 16bit recording. Unique features such as a two-position stereo microphone, a prerecord buffer that records five seconds of audio before hitting the record button, digital pitch control, and A/B segment/ repeat offer great portable possibilities for songwriters, musicians and journalists. To complement the PCM-D50 recorder, new optional accessories include a remote control, tripod stand, and microphone windscreen.

Features:

• Superb Recording Quality
  The PCM-D50 is a 96kHz/24 bit linear recorder that records in standard .WAV file format and surpasses standard DAT sound quality. A low signal-to-noise ratio provides virtually noise-free recording quality.
• Expandable Memory
  With a 4GB built-in memory, the PCM-D50 records up to six hours when recording in 44.1kHz 16bit CD quality mode. And the Memory Stick Pro-HG Duo Slot provides up to 4GB memory expandability.
• Built-in Microphones
  The PCM-D50 recorder comes equipped with a high sensitivity, built-in, two-position electret condenser stereo microphone with flexible rotation for either X-Y or Wide stereo positions.
• Playback Functions
  The PCM-D50 recorder provides MP3 playback, a special Digital Pitch Control feature that slows down playback without changing pitch, and an A/B segment repeat feature that allows you to mark and repeat segments.
• Versatile Recording Functions
  The Dual Digital Limiter feature helps prevent distortion, a pre-record buffer records five seconds of audio before hitting the record button, and Super Bit Mapping technology helps achieve, wide, dynamic range.
• PC/Macintosh Compatible
  The PCM-D50 utilizes a simple drag and drop file transfer via high-speed USB connection.
• Rugged Construction
  Constructed of lightweight metal (aluminum), the PCM- D50 recorder is built rugged to withstand the demands of pro applications.

Customer Reviews

Excellent new toy
[[ASIN:B0016NCRW4 Sony Professional Portable 24-bit Linear PCM D50 Audio Recorder

This is a wonderful tool. Being a professional musician, I've been
looking for something in this price range, and this product is the
one I've been waiting for.

It's small, portable, and rugged. The microphones are excellent
quality, and it's easy to use. As a tech-averse geezer, even I'm comfortable
with this product. Highly Recommended.

Functional and Sturdy MD/Portable DAT Replacement - Finally!
Quality-wise, this is the MiniDisc replacement people have been looking for. Sony kept out extras such as quad mic setups, overdubbing, MP3 recording, and cheap XLR inputs to focus on getting the basics right: clean mic input, useful limiting, durability (metal casing--what most MiniDisc units had, but few flash recorders currently have), and clean playback (accurate monitoring). A perk is that it has great battery life (very frequent recording and playback throughout the day = change the batteries once every 2-3 days.)

Skip the rest and get this if you want to spend less than $1200 to replace your old MiniDisc or portable sub-$600 DAT setup. If you want something better, save for the Sound Devices 702/722 (oddly numbered like the old Sharp MD 702/722 units).

I've now recorded rehearsals and individual practice sessions (orchestra/trombone) and can say this unit does an adequate job of recording. It's not great like a multi-mic, pro recording chain setup can be, but it fails to introduce noise into recordings when one uses external mics or the internal mics; other flash recorders (Edirol, Zoom, Tascam) seem to do a less than adequate job by including noisy mic preamps.

After waiting through years of noisy mic pre's in the first generations of flash recorders, I couldn't ask for more. But the Sony has three additional features that are great: there are manual controls for many basic functions; the unnoticeable limiter makes it difficult to peak; variable speed playback is toggled with a manual control. Musicians will love that a manual control toggles the variable speed playback. It is simple to listen back at half-speed (or slower)--and, like some other flash recorders (and unlike the $20-$50 tape recorders), it retains pitch. The limiter records two tracks, 20dB apart and seamlessly splices the tracks together when your levels are too high; on playback, it is hard to tell when it is activated. This makes it simple to record sessions that involve speech and live music, though I suspect editing will need to still be done to level it out. (As an example, such a setup would work for recording an interview where a violinist speaks and plays, but editing would be needed to level out the same type of interview with a brass player because brass vs. voice is often a 30dB+ difference--more than the 20dB the Sony limiter handles.)

The Bad
The mics are sensitive to air movement. This works well by itself when left inside in one place (like a normal condenser mic is setup indoors), with a windscreen, or with an external mic that is either less sensitive to air movement or has a wind screen. (Walking around while recording generates wind noise that allows other sounds to pass through while high wind outside will cover up all other sounds.)
The Sony is bulky and heavy for a portable device. This is noticeable compared to the late, tiny MiniDisc units (such as the RH1). Hopefully as the technology improves, this caliber of flash recoder, like the early portable MiniDisc recorders (remember those?), will become smaller with time.
Not So Bad: The unit requires Memory Stick Duo (Pro or Pro-HG) flash memory, but it is not much more expensive than regular SD cards (about $10-15 more) and the unit comes with 4GB of internal memory (under 2 hrs @ 24/96 or under 6 hours @ 16/44).

Reality
You can't have ultra-portable at this quality level yet. If you want a quality recorder now, spend the extra $100-200 and get the Sony to avoid buyer's remorse. If you're looking for a fun, small recorder, look at the Zoom H2 or Tascam DR-1. If you have the perfect setup and can wait for a smaller version of this, wait a while and see if the Sony gets smaller in a later model (or if another company puts the same quality into a smaller package).

Great for garage bands
Just to add to all the glowing in depth reviews out there, this recorder works perfectly for extremely loud rock music in a basement with really terrible acoustics. I can hear all the instruments distinctly and there is no noise on the recordings.

The user interface is great. The best I have seen on any complex hand held device. The layers of menus are not too deep and the buttons are labeled clearly for both their recording and navigation functions.

You will be pleased.
