Once upon a time, I saw plans for a sound digitizer for the Mac. The plans seemed relatively simple. I know the software isn't exactly pleasant, but that's no problem either. Does anyone happen to have any info on plans for such a beast?

And it comes with a _great_ piece of software called SoundEdit, from Farallon Computing. Well worth the price for just the SoundEdit software alone. Now heres my question - what other sorts of sound digitizing gear is available for the Mac? The reason I ask is, MacRecorder is limited to a maximum sample rate of 22 khz. I'd like to sample something at a lot higher frequency - say 44 khz, which is getting up past CD quality. You really notice the limitations of 22 khz if you want to use the Mac as a sampler or the like. Especially if you listen to it through a reasonable amp or stereo. The Apple Sound Chip in the IIcx, SE/30, Portable etc is supposed to be able to do '44 khz stereo sound', so I can't see why you shouldn't be able to sample at that rate and play it back through the ASC. Email replies to me please - I will summarize to the net after Xmas.

A few weeks ago, I posted a request for information on a piece of hardware that can do a job similar to MacRecorder from Farralon. Little did I know that the "SID Trio" was hard at work. Last night on GEnie I ran across a file in the Mac file are (Page 606) that contained the complete schematics, component lists (with part numbers), instructions for construction and software for driving the device for SID (Sound Input Device). From the looks of the documentation, SID can be built for about $30, and I can't see that it lacks ANY of the functionality of the original MacRecorder. If anyone is interested in more info, check file 16001 (I think) on GEnie, or leave me a message and I'll post the address of the SID Trio.

If you use the serial port. How about somebody setting a new standard: 44.1 kHz sampling (mono or stereo) SCSI buffered/intelligent transfer At least standardize the communications interface so there is some clear path between the cheap (SID) and big (studio) digitizer/sampler units. This would also make it easy for software developers to support a wide range of devices, and possibly convince some of them to write some decent sound software. Come on Farallon, how about doing it right? Chris

The MacRecroder software SOUNDEDIT address this concern by providing support for stereo sound via two MacRecorders, each doing a particular channel at 22Khz...

But has anybody seen anything - hardware, software - that can handle over 22 khz?? Even Farallon's excellent SoundEdit program only handles up to 22khz. BTW, I know about the expensive NuBus boards that do everything short of signing you up for a record contract.

(PDE's I can remember, multiplication - that's another matter) Chris ps. priced a sampler lately? Some of them have a reason for being expensive, but most don't. pps. (ragge@nada.kth.se) I'll have to try an external clock on the serial port, thanks for the suggestion.

These are fully functional 44.1 Khz / 16-bit systems that both sample and generate sound. Option is available for DAT interface too.

Sorry. If you want real-time sample input, MIDI just can't deliver. MIDI is ~30K baud. That'll give you 3K samples/sec, or 1500 Hz. Oh well. I still believe that a good, cheap SCSI data IO device could be easily built. Let's see... SCSI transceiver, cheap 8-bit CPU (or even a 68K), 256K IO buffer, memory control, and a slot to insert your favorite card(s).

If you have a sampler, you can sample and edit to your heart's content (wd ?), then set the synth at bulk transfer and go for lunch. h+ -- --- Stay alert ! - Trust no one ! - Keep your laser handy ! --- h+@nada.kth.se == h+@proxxi.se == Jon Watte longer .sig available on request

If it is compatible with MacRecorder, i.e. will work with MacRecorder software, someone should sell them. Reason is that you can record stereo with MacRecorder, but you have to buy another copy of the whole hardware/software package just to get the additional sampling hardware. So, if anyone is going to make these things up in their garage, don't forget to make some extras and advertise them for sale. --dave yost yost@esquire.dpw.COM

Yeah, except that the Roland would sound like utter crap, be severely crippled in capabilities, and be an order of magnitude harder to work with unless you also buy a Mac to go along with it. You get what you pay for, but, then again, not everyone needs to record an album at home.

Mac II's have TWO 44.1Khz output channels. That is, the built-in hardware can produce stereo, 8-bit, 44.1 K samples/sec. When digitizing, the MacRecorder is limited to 22 K samples/sec. A Mac II (because of it's speed, probably) can simultaneously accept input from two MacRecorders at 22 K, giving stereo, 8-bit, 22 K samples/sec. -Justin vallon@sbcs.sunysb.edu
