    Andrea Superbeam and 2 soundcards

    Hi!
    First a few words about my setup;
    I have 2 soundcards, 1 is the auzentech X-Meridian and the other is the onboard realtek ALC880.
    I play music using foobar plugin, utilizing ASIO through the X-Meridian (this is one of the major reasons I bought X-Meridian + its output quality). Movies, Windows sounds etc are send to onboard realtek, then output through SPDIF to X-Meridian SPDIF input, which is made directly available to the X-Meridian outputs. So, every sound is send through X-Meridian to my amplifiers (I do processing before that but it doesn't matter for what I'm trying to ask)

    Now, concerning mobile phone input, I use a cheap microphone (Nokia Visor Microphone) I got off ebay some years ago. I use the .net Bluetooth Mobilephone Plugin and mic is connected to onboard realtec (since it supports Acoustic Echo Cancellation). Bluetooth Mobilephone Plugin is very flexible in that it allows you to specify any system audio input/output device. For Acoustic Echo Cancellation to work, I have to specify onboard Realtec as output of the Mobilephone Plugin(Most soundcards that support this feature have this requirement). Again, no problem, since as I described above, onboard Realtec sends through SPDIF to X-Meridian SPDIF input.I would describe the Echo Cancellation results as satisfactory, meaning that I'm not planning to make major changes there.

    Now, moving forward to my question. In some days, DigitalFX 5 will be released and I'm planning to use RRVoice. I've made my mind and I'll buy Andrea Superbeam found Here . I'll not use the echo cancellation features of it, since that would require connecting the outputs of the Andrea USB soundcard. This is impossible in my setup and as I said I'm quite satisfied with the results of the onboard Realtek, plus I'm not willing to use any AD conerter in my sound chain(that would most likely induce noise). I'll use only the noise elimination features of the Andrea, so that I'll be able to effectively use RRVoice.

    So, how do you suggest my mic(s) setup should be?

    1) Use the existing mic (cheap NOKIA sunvisor mic) on the realtek for mobilephone and use the Andrea on its USB soundcard for RRVOICE, using its noise elimination features.
    2) Use a Y Splitter to share the ANDREA mic between the onboard Realtec and the ANDREA usb soundcard. I'm not sure if this is possible and I'm seeking for answers. Is there any risk destroying the Andrea mic or the soundcards' mic inputs by going this route?
    3)Totally avoid using Andrea usb soundcard and connect the Andrea microphone to the onboard Realtek, throwing away also the Nokia mic and enabling noise suppression on the onboard Realtek(of which I'm not sure if it's quite effective for RRVOICE).
    4)Something else. Preferably w/o using any AD converter in my audio chain and not buying something expensive.

    I'm mainly interested on option 2 above, but I explained my concerns. Hope someone has more knowledge on that!

    Use this microphone. It plugs into USB not your soundcard, so you can continue to use your existing soundcard. It comes with noise cancellation technology, which you should definitely use if you're using with RRVoice. I am using two of these with RRVoice (one in office and other in car) and they're terrific. See this post, this post and the couple of posts after it on the DFX thread.

    Thanks for the reply. Although not quite what I was asking. Mainly I'm wondering about any implications on connecting the Andrea Superbeam array mic on two soundcards' mic inputs.

    If its echo cancellation your looking for, the buy the Pheonix SOHO conference card. You mod it to get 5V power so you dont have to plug it into a pci slot, then you connect it to your existing onboard soundcard. Problem with the Andrea is that its all software driven so its going to cause slowdown. The SOHO is 100% hardware driven so no worries.

    Yes, Phoenix SOHO is a fantastic piece of hardware. Examining its specification , it's clear that is not suitable for my case. It stands between my soundcard and my amplifiers which cannot be implemented in my case. My main soundcard (X-Meridian) outputs 4 stereo channels (after some crossover VST plugins) and it's connected with SPDIF with my onboard soundcard which sufficiently does echo cancellation for me. So, no single stereo channel output for me, which means no SOHO.

    In any case, I'll order the Andrea and see if I can connect it to my onboard ALC880. It might support beam forming (it supports echo and noise cancellation for sure). If it supports stereo microphones like Andrea Superbeam, I might go that route. If not, I might use 2 microphones.

    Not too sure if I can be of much help with your exact question, but hopefully I can clear one thing up a little bit.

    The Andrea mic that kbreeden linked to above:

    It does have a dongle, and sometimes incorrectly referred to as a sound card. It is NOT a sound card.

    It is a USB interface, that lets you plug the 1/8 stereo jack (Think headphone plug) into a USB port. The Andrea is a powered mic, and will not work plugged directly into a sound card. I just tested it here, by plugging it into my mic port on my motherboard. I fired up MS Sound recorder and talked VERY loudly into the Andrea mic. When I play it back, I can hear myself talking into the mic, but just barely.

    The USB device that comes with the Andrea is an amplifier, as well as having circuitry to perform the noise canceling. It does not have any audio output at all. It does not interfere with any other sound cards installed on your system.

    As for you saying you do not need noise canceling, I would rethink that if you want to use it for voice recognition in the car

    Here is a demo I did showing the Andrea with the noise canceling turned off, and on. Here is the demo.

    On my particular setup, I have a standard mic plugged into the mic in jack on my mother boards built in sound card. I use that mic to record the audio for my front facing web cam. I also have the Andrea mic plugged in via USB that I use for voice recognition. When you go into any program that allows audio recording, and you use the pull down to select the device to record from, it shows the standard mic on your sound card, as well as the Andrea.

    In the screen shot below, you will see I am also using the ReatTek on board sound card that you are using.

    Thats interesting.... I have the Andrea Mic also, but never used the dongle. When i would try to use Mic for voice recognition, it would say there is a mic there, but nothing ever picked up. So its my guess that all though the SOHO is powered, it doesnt have enough power to power the Andrea? How can I solve that issue? I think the MoBo itself supports stereo mics, so it should provide power to them, right?

    Maybe I should rethink my install. Do you have to use the Andrea software? Can I just install the drivers, then connect the SOHO to the Andrea dongle?

    Hijack,

    You ought to try it with the Andrea software. I havent noticed any meaningful degradation of performance with the software. In fact, in taskmanager CPU usage doesn't even register for Audiocommander.exe, the Andrea software, when I issue a voice command.

    Maybe because English is not my native language, I might wasn't clear on that. I need the Andrea ONLY for noise suppression(or noise cancellation or whatever is called). I'll definitely use RRVoice as stated on my first post once you release DFX5 .I just don't need the Andrea for echo cancellation since my onboard Realtek ALC880 does the job fine for me, using a cheap NOKIA sunvisor mic.

    In any case, your post was very helpful, since it clarifies that ANDREA mic doesn't work with your onboard Realtek, so most propably it won't work for me also. So, that makes me use a similar setup as yours. I'll use ANDREA with the usb adapter (Or the other one which is bundled with a USB soundcard) for RRVOICE and make use of its noice cancellation features only, this means no echo cancellation on ANDREA. Then I'll use the standard cheap NOKIA microphone I'm already using for echo cancellation. Only disadvantage is that I'll have to use 2 mics, but if that is all it takes, I'll go for it since ,on the paper at least, it's gonna work.

    Thanks again! That definitely helped me.

    By the way, John, I saw that you're using This version which has the USB-SA soundcard bundles. I believe this version is a true soundcard, as it has output also. The other version has just a SUMA adapter. It's not clarified anywhere, but I believe that both versions support noise cancellation (filters), but only the USB Soundcard version (USB-SA) supports echo cancellation. This is implied by the fact that for echo cancellation to work, the soundcard has to compare its input to its output, effectively "removing" what appears on its output FROM the input to make echo cancellation work.

    Do you have any more info on that?

    No, John is using the one with just the adapter as discussed in the posts I linked to earlier. He and I had this exact discussion on the DFX thread a couple of days ago.
