Hi, all,
With all the iPods and other HD recorders out there, you'd think that one of them would have tumbled to the idea that you could also do decent recordings from a mic using one of their units. But from what I can tell, they use 4kHz sampling rates, low bit rates, etc. There are some minidisk recorders out there that have mini plugs for microphones, and apparently have a better quality that they record at. But...if you were looking for a basic mono or stereo recorder that had pretty decent sound, and was hopefully smaller than the typical DAT or cassette recorder, what would you look at?

But from what I can tell, they use 4kHz sampling rates, low bit rates, etc. Not at all. The iRiver HD units can record from an external mic in stereo at the standard 16/44.1 rate. Their principal limitation is that, although the gain is adjustable, there is no display to help you set the level, and the mic preamp might not have enough gain for recording string quartets or other "quiet" music. |

But...if you were looking for a basic mono or stereo recorder that had pretty decent sound, and was hopefully smaller than the typical DAT or cassette recorder, what would you look at? Well, I just returned from 11 days in China recording Beethoven, Vaughan-Williams, Wagner, Bizet, Mozart, and other oldies with a Marantz PMD670 with a 1 Gb CF chip. Sounds absolutely fine. Too bad the concert halls and the sound systems/"engineers" weren't up to the task. Other than the cell phones ringing in the audience(s), people taking calls and talking during the performances, and sound system howls, squeals, general overamplification to a near unbearable level, and the nearly unbreathable air, everything was great. Check out the PMD670. For about $800 (($700 for the machine plus $100 for the chip (actually $89 at Fry's with a $20 rebate))), you get a nice, usable solution if your problem is one that it will solve. T.

Have a look at Sony's Hi-MD. The full scoop can be found at http://www.minidisc.org It has pre amps (which have not been characterized yet by anyone so far as I know) does 44.1 kHz, can handle optical digital in and record to either their latest ATRAC compression (which hasn't fared too well at all against the competing codecs in listening tests) or, more interestingly, to 16 bit PCM. The recordings can be uploaded at high speed but they are encapsulated in a proprietary format and currently the only thing you can do is play an encapsulated PCM file with their app. There is a hack at the above site that claims to be able to reencapsulate them to .wav format and Sony has quietly announced their intention to ship a utility this fall that does the same. The medium holds about a gigabyte. There are other solutions coming down the pike from Tascam and I think from Yamaha that use CF media but they aren't here yet. If you don't need pre-amps there is also the iRiver line of HD recorders. Hard drives packaged so close to analog recording circuitry are problematic due to the high di/dt noise they generate. You won't find a HD unit with real pre-amps for this reason and even the line in devices have noise well above -96 dBFS. Bob -- "Things should be described as simply as possible, but no simpler." A.

Human imagination is insufficient to comprehend the totality
of the experience, both in terms of the musical experience - which, for the group, was quite a success - and the environmental factors of the Chinese reality. If I were to relate some of what I experienced, you would insist that I was making it up. My own imagination is insufficient to construct such things. Although lunch at the rotating observation deck of the Tianjin radio and television broadcasting tower (the 7th tallest in the world at the time they made that boast) was quite pleasant. Although I saw Allen & Heath (GL series) and Behringer (MX9000) mixing consoles, Toa and Cerwin-Vega speakers, it is my impression that the technical people I encountered are (understandably) unfamiliar with Western music and how it should be mic'd and amplified. Even though I was not responsible for setting up the stage and mixing the shows, I did have to reposition a number of mics in all venues and even tried to communicate proper levels, etc. which I was told afterward were virtually ignored. And don't get me started on the food and sanitary facilities. For the world's sake, I pray that things change by 2008 - and more than just on the surface.

Thanks, everyone for the great input. It looks like there are really good
solutions out there, but they are cost prohibitive. The Hi-MD stuff may be the simplest solution near-term, but one wonders about the kind of microphone you get when you buy a Sony ECM-MS907 Mic to go with it...at least they use OFC cable!!! ;-) "Church Audio" (an EBay-only store, I gather) has some alternatives for external preamps and microphones, but again...one wonders.

Well, I might just do that. Gotta decompress a little, and
get caught up on this end. At least the Airbus 340-600 is a nice ride there and back...It's about the only thing that didn't go wrong. Oh, wait - a three-hour delay at LAX outbound, and a one-hour delay after landing inbound because China Eastern didn't have a jetway available for de-planing (but that's not the airplane's fault). Amazingly enough, not once did either my bags or gear get examined - not even questioned. Before leaving, I stopped at customs and got a registration certificate to get the gear back in without hassle. Never needed it. A member of the group (this was a collection of over 100 musicians - orchestra and chorus, many Local 47, and many from other parts of the country, Australia and Canada) is putting together a Web site with pix from everybody. It'll take a little while for that to be completed, and I'll see if there is anything appropriate to be shared.

Shanghai at night, then on to Beijing. I was surprised how
dark their cities are at night. Having flown into many of our major metropolitan airports (LAX, JFK, DFW, etc.) I was expecting a real light show, especially into a city of 32 million people (SHA).

Yeah, it sounds great after I convolve the compensating FIR's I calculate from measurements with the recordings. The frequency magnitude response can be made very flat and the group delay very coherent. It's self noise is low enough to be generally useful and there's no distortion I can hear even in pretty high SPL live situations. I've not stuffed one down the throat of a sax yet but with a sax distortion would be pretty hard to hear anyway. :-) I've done enough experimenting with these measurement and computational techniques that the time coherence in a stereo mic is something that really stands out for me now. After this kind of compensation, things are precisely located rather than somewhere out there in the general direction of... Of course, the absolute accuracy of any stereo image depends on the overall directional nature of the configuration but the relative location of anything within that, perhaps warped, space is heard with less spatial smear after compensation. Something that makes a big difference with that mic is to remove the two screws holding the outer, protective shroud and sliding it off to more expose the capsules when in use. With it in place, there is so much HF dispersion that the time compensation is not nearly as effective. Even without compensation, the HF response of the mic is improved considerably by removal of that shroud. Bob -- "Things should be described as simply as possible, but no simpler." A. Einstein |

If, that is, you've got a DAW which can convert between stereo and mid/side and has stereo convolution. I had a little PC application in the works that would do that and optionally apply transformations to other mics ala Antares Mic Modeler but the coder and I had a falling out over control of the project and I let him go. The straw was when he insisted on clipping IEEE float results if they were greater than one and I couldn't talk him out of it. :-( Got a nice app very near completion for OSX too with a much more managable collaborator but got stalled on it a while back when I began working on some other things and have not come back to it.
