Not at all upset with you. Just annoyed that this is getting more complicated than I was led to believe. I went from having a simple answer that no additional equipment would be needed beyond the USB mic, and I could use standard analog audio output to generate the test tones, to your response, thus it feels like it's going backwards.
As I understood it, the audio output portion (HDMI vs. whatever) was secondary; the initial impetus was about the INPUT portion, i.e. the USB mic obviating the need for additional gear (external soundcard, phantom power, etc). The HDMI output aspect was secondary "gravy" for people who were fascinated by the idea of being able to ping each channel individually. But when jevansoh originally introduced the topic it was not limited in scope to the HDMI output option; the specific form of signal generation wasn't really relevant. I don't know at what point the two merged but when it was initially discussed in the Audyssey thread the two were NOT linked.
Not sure, but maybe it was the part where Jason explicitly said that was the case when this was initially being pitched in the Audyssey thread?
Here's some more info for everyone.
While it is true that REW generates the signal internally, meaning you will have to hook your computer/laptop up to any available stereo input on your AVR, you will not need to use an external CD/DVD Player and CD/(DVD??) like you do with Omnimic/RTZ so that pretty much cancels each other out as far as I'm concerned.
There are no other "black boxes" needed. You will NOT need a full duplex sound card because you aren't using the sound card's mic input and speaker/line output at the same time, as you'll be using the USB Mic. So the built-in sound card that every PC/Laptop has works fine. (Using it this way myself on a cheap laptop)
Yes, the output/jack on the sound card is 1/8" stereo mini and Yes, the input on the AVR is RCA, but that is taken care of by a $3.00 1/8" to RCA Splitter/Y-Adapter that I bet most of you already have.
You will NOT need an "external" sound card. I'm SURE your PC/Laptop has a sound card and the one that is built-in is more than adequate if manufactured in the last 10 years or so. Promise! (My business is computer hardware/software, sales and service, in business since 1994, so I'm sure of this)
Yes, the front AUX is exactly what I use. If you want "easy" (actually, every method is very easy, but this is the long-term/in-use tried and true method) and only care about the front 3 channels as far as testing goes, then you can use a simple RCA cable, and 25' or so is fine, but I wouldn't go more than 50' max, and stay as close to 25' as possible.
Monoprice makes great ones and you can do the same for even less. All they do is use standard RG-6 Sat/CATV cable and put some RCA plugs on the end. I make my own for even less, but if you don't want to fool with it and don't need custom lengths, their prices cannot be beat.
You'll simply plug the mic in to your PC/Laptop (Up to 15' standard USB extension cable can be used and if you need longer than that, Monoprice again has wonderful and cheap options for amplified USB cables for much longer lengths) and then from the sound card in the same computer you'll run an RCA cable back into your pre-pro's AUX input.
No No no... NOT $200. You do not need any external sound card if using a USB Mic because you no longer need full duplex capabilities since you won't be using the sound card for "input" (that will be the USB Mic now) at the same time as "output." The output is all you'll be using on the sound card and I haven't seen a PC/Laptop since about 1997 that doesn't have a built-in sound card, so I'm sure you don't have to purchase anything but the Mic which is less than $100.
Yes, the headphone out is fine. You'll simply plug an RCA cable from that (may need a 1/8" to RCA adapter for a buck or so at Monoprice) into the front AUX on your Onkyo, then plug the Mic into a USB port on the same laptop and that's it! If doing it this way, you won't even need to fool with the ASIO driver because that's just for HDMI and if you want all 8 channels.
So, yeah, I think that was a reasonable inference on my part.
Well I guess you missed this exchange. It's disappointing to me that the scope has narrowed from the original introduction in the Audyssey thread such that it's now exclusionary towards those who don't have the HDMI output option.
Again, I don't understand why the OUTPUT aspect has to be linked with the input side. It's almost certain that I am misunderstanding something, but I though the biggest revelation of the process was the support for PnP (or almost) USB mics making the intro to REW much more accessible. What does it matter how the funny test tone sounds gets from the laptop to the speakers? If the speakers make noise, can't you measure it?
A microphone input (mic-in) on a soundcard is not suitable (many laptops only have mic-in).
OK, that's all warning about the mic INPUT portion. That's the part that is now obviated by the USB mic (as I understood it). All I'm talking about is the sound OUTPUT, the signal generation portion.
I'm not trying to be a dick, and I truly don't understand enough about the topic to know where I'm going astray, but I feel like what you are telling me does not jive with what was originally discussed during the genesis of this idea in the Audyssey thread.
