I just received my Andrea USB to use with my audio technica pro but I am getting horrible signal-to-noise ratio in the microphone test. It looks much worse than by using my RME Fireface. I have no doubt that my interface is much better but I was under the impression impression that the country would do better.

Do I need a specific software or driver? The driver installed is 6.1.7601.17514. The model is USBD2-A. I am also attaching the screenshot, the Andrea is on the left and the RME on the right.

Any feedback from the experts is greatly appreciated.

In the past, I have had problems with getting microphones to work well with onboard sound cards. I'm no expert on the matter by any means but, your problem could be caused by the onboard soundcard and the microphone not playing well together.

There are a lot of external soundcards that you can purchase from Knowbrainer store. You might want to take a look at them while you wait for someone more experienced to weigh in.

I am sorry but this is not an onboard card, I stated it is an Andrea USB card, the one suggested many people.

Sorry about that. I didn't catch that part of your post and initially. So, I took a look at your profile and it indicated that you were using the onboard soundcard. So that's why I thought the problem was due to the use of the onboard soundcard.

That being said, I now have no idea what your problem could be.

We removed your JPEG because it was a dead link but we are wondering which USB soundcard you actually purchased. Andrea Electronics makes 3 basic models which are the PureAudio full-duplex with a pigtail (on the left picture below), the 1\2 duplex (right picture) and another USB soundcard which looks like the 1\2 duplex but is actually a full duplex with 2 input jacks instead of the 3 input jacks which are present on the 1\2 duplex. We mention this because the later model has been known to be problematic and is a discontinued item.

Also note that the PureAudio USB soundcard we offer is the 2nd generation which includes a hotter input and has a pigtail. The 1st generation models do not include the pigtail and struggle on larger microphone elements such as the Pro 8HEmW.

                                      
You shouldn't need to download a driver with any Andrea Electronics USB soundcard. Additionally, you needn't be concerned about the signal-to-noise ratio, as long as you pass the Audio Check because the noise is outside of NaturallySpeaking's range.

thanks Lunis for your precious feedback. I am a bit confused because the picture of the 1/2 duplex you posted seems to show only two inputs exactly like the one I bought, it does not have an icon on the side of USB cable. This http://www.pcaspeech.com/onlinestore/usrimage/andreausbadap.jpg clearly shows 3 inputs and it is not the one I have nor looks like the one in your picture. I am just wondering if I should return this one I bought. Mine only has two inputs.

 I am trying to repost the picture http://imageshack.us/photo/my-images/607/andreaprotest.jpg/

 

PS: what is a pigtail?

Unfortunately our previous picture isn't very large but it is identical to the 1 displayed on the PCA website which is an appropriate 1\2 duplex model. Interesting as it sounds, the 1\2 duplex pod has 3 inputs and the full-duplex pod has 2 inputs. The 3rd input is at the bottom of the USB cable and is designed as a pass-through. The 1\2 duplex sound card only generates sound output but includes a patch cord which you can attach the output of your integrated soundcard to feed sound into it; creating a pseudo-full-duplex sound card. Unfortunately, this actually detracts from the accuracy so we deliberately leave the patch cord out of the equation to prevent end-users from trying this bad idea. Think of this approach as someone removing the cigarette from your mouth.

Bottom line: You purchased an overpriced full-duplex Andrea USB soundcard that was discontinued years ago. Unfortunately, this item is still available; even on the Andrea Electronics website but that doesn't mean it should be used. You'll find every
USB Pod that we recommend on our website under the previous link. If you don't see a particular model, it means that it didn't measure up to our standards. There are lots of other USB soundcards such as Plantronics and Logitech that are not powerful enough to drive a large microphone element like the Pro 8HEmW microphone. Sound Blaster and Turtle Beach also offer USB soundcards but unfortunately, only include a line input as opposed to an appropriate microphone input so we don't recommend them either. Now you know why we ONLY recommend the PureAudio USB-SA Pod and ANC USB Pod external USB soundcards for the Pro 8HEmW.

thanks again! I only paid $9 for this. Although I have to say the pic of your andrea is a bit misleading. I really don't see the icon pertaining to the third input, it should be seen because the other icon are easily discernible.

 

How is this older version problematic?

Per your request, we have changed the icon on our USB soundcard page but this soundcard has been around for a long time. The original icon was the only available picture for the 1st few years. We simply don't spend a lot of time updating pictures on our website. Our office manager Tom takes care of most of the day to day website changes but keeping up with the latest digital recorder, microphone, soundcard and speech recognition technologies is a bit of a challenge. To our knowledge, none of our customers have ever commented that the picture is misleading but we concede that you have a point. However to be fair, most of our customers are not looking for a $9 non-Windows 7 compliant, out of production USB soundcard either . We are not picking on you but rather pointing out that it is sometimes better to purchase from a specialist rather than looking for the best deal from liquidators because there's usually a good reason when the price on something is too good to be true.

Please don't take this the wrong way but we really don't have enough time to experiment with discontinued technology when we have numerous other viable lower-priced solutions. When the original full-duplex Andrea Electronics soundcard was 1st released, it was a $60 item. Part of the reason for the higher price tag is because Andrea Electronics created the 1st full-duplex USB soundcard that included an additional specialized hot chip that injected the USB soundcard driver into the OS rather than using a generic driver or having to install software. When this soundcard was originally released, it was designed to support Windows 98 NT and XP. Andrea Electronics ceased production on this unit around the turn-of-the-century because it was too expensive to produce. Our best guess is that the driver is incompatible with Windows Vista or Windows 7.

Lunis, you are correct in so many ways. However having already spent quite a bit for the microphone I had to work with a limited budget. Thanks for changing the picture I'm sure future customers will appreciate that. Just to follow up with the initial problems I had, now the sound card is performing quite well. The signal to noise ratio is much better now, it really depends on what type of environment I do the audio Wizard. Initially I was doing it in a noisier environment. Now I get very good results just at home with minimal environmental noise. So just in case someone else wonders this Andrea USB is working just fine, maybe it's not the top of the line but a good option.

Lunis
what are the differences between the two sound cards that you mentioned above? I'm looking for something to go with the Audio Technica headset. Ideally I would like something that would allow me to speak very softly. I was also thinking it would be nice if one of them had an input that would allow me to plug earbuds into it, since the Audio Technica does not come with any earphones. I was looking at the pictures posted on the shop and I cannot tell for sure if they both have an audio out input.

The 1\2 duplex ANC USB Pod external USB soundcard is our favorite for the Audio-Technica Pro 8HEmW because it's only 1\2 duplex, doesn't steal your sound system and is all you need. We also like the fact that it's a little hotter than any other USB soundcard (which gives you the option of speaking at a lower volume level) but if you are looking for small profile, we recommend the full-duplex PureAudio USB-SA Pod external soundcard because it's about a 1\4 of the weight and size of the 1\2 duplex Andrea soundcard. Note that both soundcards work equally well.

I was browsing the Andrea Electronics website after I read your comment earlier. And I noticed that on their second generation soundcard the website that it had enhanced noise cancellation features. I thought I had read on this forum that most of the soundcard's were pretty much the same except for a few minor differences.

Does the second generation soundcard really have anything in it that allows it to have a better noise cancellation ability?

That’s called advertising. The only current USB soundcard that offers additional noise filtering, is the Buddy 7G USB Pod which unfortunately, doesn't work on large diaphragm microphones like the Pro 8HEmW.

That is exactly what I was thinking. Is there any more word on the speechwhere soundcard that is supposed to be coming out?

We suspect that the SpeechWare USB soundcard is minimally several months away because we have not yet seen the prototype.

Hi everyone,

I own the andrea 1/2 duplex usb and the AT PRO and it works pretty well with a soft voice input in noisy office environments.

It seems like that is the soundcard to get if you want to be able to dictate very softly. Not meaning to disregard all the advice, I decided to go with the Andrea Electronics pure audio soundcard. I am hoping to use the headset at work, so I thought it might be a good idea to be able to plug a pair of earbuds into the soundcard. This way I would be able to use the read that command to be able to proofread my dictation. I know that I could always use speakers to get the job done but I would like to be able to use the command without potentially bothering anyone else.

i confirm that with the andrea you can speak softly and it works fairly well depending on your computer, background noise and how soft you speak.

thanks for the input. I always liked the comfort of knowing that if I have to I can dictate without bothering anyone around me. Or more specifically that I can dictate softly enough so that I will be self-conscious about using speech recognition software.

i don't like to dictate louder than i have to, i always like to keep a lower volume. Less strain on your voice.
