I have digital recorders what outputs SPDIF, not optical but the same format. I want to bring the audio into a PC using USB.
I can find converters for USB to SPDIF, and USB to analog or analog to USB.
I can find one box that converts SPDIF to optical, then add another box that converts optical to USB.
The recorders are " Fostex VF08". The input & output are 75 ohm coax digital stereo.
The old DAT recorders also use this format and have the same problem.
Thanks RonS.

 

PCM2906 has S/PDIF in USB out.

A bunch of the Burr-Brown/TI USB codec chips include S/PDIF I/O, but finding boxes that bother to implement input is another story. There's the ART USB Phono Plus which looks just about perfect.
A cheaper option is the ADS Tech RDX-150 Instant Music; it's pretty close to a copy of a B-B reference design and has both line and Toslink I/O; there's a bunch on ebay, but I've found them them at thrift stores for as little as $4.

Alternatively, if you have a computer with expansion slots (PCI, PCI-E), various Soundblaster cards included S/PDIF inputs on an expansion header. I've added Toslink input to an Audigy 2 ZS with just a cable and Toslink receiver. Some deluxe cards shipped with a "Live Drive" module that mounts in a drive bay or externally and makes use of that expansion header; I scored one of those for my Audigy at a computer recycler. Given that old but still capable computers are basically free these days, if you can afford the desk space, consider setting up an older dual-core system for A/V capture and editing.

 

I may get a RDX150 and remove the Toslink optical IO parts.
I can find optical "light pipe" SPDIF to USB boxes but I need coax to USB. The PCM2906 can directly drive a coax 75 ohm cable or drive a Toslink fiber optic transceiver.

This project just got kicked down the road a month, but I need to do something soon.
Thanks for the help.

 

I just found Fosi Audio Q3 and Q4. Thanks, bassbindevil I found it on ebay.
I can't see any difference between Q3 & Q4. (delta $10.00)
It has the COAXIAL in and USB so I think it will work.

I found it on Amazon also, but unfortunately the USB is apparently only an input.



You might look at this.
You may have to convert from digital audio to optical TOSLINK, and then to USB.

I think you are right. Just saved me $50. I read through 39 Q&A and no one is using it to input into the computer, only output from the computer Thanks.

 

I now have a "Edirol UA1D SPDIF Digital Audio to USB". It is old but works.

If you want something new and better. Look at " Focusrite Scarlett 18i8 ". It includes mic preamps, line in and out, headphone jacks and more. Get versios -2 or -3 but not -1.
