Sound ADC

Hi,
I would like to measure an ADC of a sound signal. The sound wave is given to the mike input of the PC. when I used the example VI's I am getting the same signal as of my input. Is there any way just to measure the ADC of that sound wave. Appreciate your help.
thank you,
Mudda.

Hello,
By ADC I presume you mean analog to digitical conversion, and by data, I presume you mean the digital data returned by the sound VIs. You will have access to the data in 8 or 16 bits and mono or stereo form from your sound card. I would recommend taking a look at the example VI entitled Simultaneous Sound IO.vi; you can find it in the example finder (click Help -> Find Examples... in LabVIEW) by navigating as shown in the attached example finder screenshot.
I think this will give you a good idea of how to use the sound VIs, and extract relevant sound data!
Thank you,
Best Regards,
JLS

DVI to ADC adapter forcing powerbook to shut down on connection

Hi there,
I have been using my powerbook 1.25GHz for about 8 months with my DVI to ADC adapter to connect to my 22" cinema display with no troubles whatsoever. Yesterday evening when I came home as soon as connected the adapter to my powerbook- it shut down my powerbook within a couple of seconds. Not only that I was blasted with a 3-5 second low tone from my powerbook as it attempted to restart. At the same time the sleep light (one that purrs softly in sleep mode on the powerbook) flashed in quick succession for the length of time that my powerbook made the the long beep noise.
Following this the computer then makes the usual start up noise but nothing happens on either my powerbook display or the 22" display. I am then required to take out the adapter connection from my powerbook and my computer restarts normally after holding down the start button again.
I have tried a few times now to connect the adapter with the same problem. Has anyone else experienced this or have any idea what the sound being emitted is all about and the disco light display from my powerbook?
Would be grateful for some hints... Thanks!
1.25 GHz PowerPC G4 Powerbook Mac OS X (10.3.9)

The exact same things (low tone, furiously flashing sleep light) has happened to me on several occasions, and it happened again today. I just googled up the symptoms and this is where I landed. The only thing I can correlate among our experiences is that the DVI connection on the powerbook is involved (the problem may or may not have anything to do with the ADC adapter).
For my problem, it's usually occurred after I've either just connected or disconnected a second display using an Apple dvi-->adc powered adapter or a small unpowered dongle (dvi -->vga) for an lcd projector. The restart after either one fails can take quite awhile.
Twice in the past six months, I've been at the "two minute warning" before a presentation, and the book has crapped out just as I connect it to the projector and then it's gone into the psycho light and sound mode you described. Today's failure occurred after unhooking from the powered Apple DVI-->ADC adapter at my desk to go down the hall for a meeting. The computer went into blue screen and stayed there after it was disconnected from the Studio Display and DVI-->ADC adapter. Attempting to hard reset/powerdown by holding down the power button initiated the tone/light flashing.
These few cases may seem pretty isolated, but perhaps a pattern will emerge if people keep adding their experiences.

Mini with 22" ADC Cinema Display w/ADC-DVI

Greetings...
I've been playing with my new 1.4Ghz mini and the display I happen to have free right now is an original 22" Cinema Display. I have the ADC to DVI adapter for this display and it's rock solid on my old G4 Sawtooth. Anyway on the mini it works very nicely exept for one problem. I get a flicker that seems to tie to system activity. May be voltage variations effecting the internal video DVI drivers. OK my question it. 1) Has anyone else out there tried this combination? (Apple's monitor compatibility chart says it's supported so I know somone at Apple tried it). 2) Do you have any image stability issues like flickering. I'm asking this because I'm now wondering if maybe my little guy is a bit faulty in the video department. I'll try my new 20" display tomorrow to see if it has the same problem.
Anyway this is an amazing little box. BTW mine currently has the minimum RAM but that will change as soon as I put this video issue to bed. Hope to use it in my studio because it's so quiet... Very nice in the sound department.
Enjoy,
--Bryan

Good news...
Well I managed to locate a rev B version of the DVI-ADC adapter. First good news is the price is now down to $99 from the original $150. Second good news is that the /B version seems to work. No more flicker!!
Hey Michael L... Thanks for the suggestion it worked!!
So while this isn't the cheapest solution, it does seem to work so far and considering the cost of a new 22 or 23" monitor vs. using my excellent 22" ADC Cinema Display I'm feeling OK about it.
So John you might want to give a rev. /B version of the adapter a try. BTW the actual adapter is absolutely identical to the REV /A version on the outside the only difference it the serial number is in a different range. If you buy an open box make sure the serial number matches on the box that shows the /B revision matches the actual unit.
Happy Hunting... They are not easy to find. Yeah I know this $600 Mac is starting to rack up the bucks but hey considering it has better performance than my original G4 Sawtooth that I paid like 5X as much for I can't complain too loud...
This will hold until Apple can produce a new truly drool worthy high end machine. The bar just went up with the introduction of the mini. The new once has got to be small, it's got to be silent and it goes with out saying it's got to be so fast it will make you cry. Until then I'll use what I have right now...
Next I need to track down a good 1GB stick of ram for the Mini...
Enjoy,

G5 clicks off when 15" or 17" ADC Display is connected

I just bought a 17" ADC Apple Display to use with my Dual G5 2.5Ghz. My 15" ADC Apple Display was working great. When I attached the 17", I heard a clicking sound within the G5. It then wouldn't power up. I attached a DVI to VGA Adapter and it powered up with the VGA monitor attached. I went back to my 15" ADC and now the G5 clicks when I connect that monitor. I tried it on a Dual G5 2.0Ghz and it now does the exact same thing. I hit the button and it won't power up. I attach the DVI to VGA Adapter with a VGA monitor to the Dual G5 2.0Ghz and it starts right up. Anyone come across this?

Some display parameters are stored in PRAM, so you can try resetting PRAM.

Old Cinema Display 22" won't work with DVI-ADC adapter & Mac Pro

So, I want to use my old 22" ADC Cinema Display with my new Mac Pro with the Radeon x1900 card.
And I was told to buy the DVI to ADC adapter, which I did.
But it doesn't work! The adapter powers up my monitor, and it shows up in the Display settings of system prefs, but the monitor remains DARK.
Anyone hear of this happening? I spent an hour with Apple Care phone support. They have no idea what to do.
Is the 22" (model #M8149) just not compatible with this adapter? I'd hate to have to buy a whole new monitor!

Yes, I tried re-setting the PRAM as well. Didn't work.
I've gone into the Monitor display settings and clicked "Detect Displays"...I've changed the Hz on the VGA monitor that I have plugged in simultaneously (a Gateway FPD1510). Not working.
As I mentioned, the computer does detect the monitor...it shows up in the Display Arrangement window and I can change its resolution, etc.
And the power light is on.
It's just that the screen in black.
Is this monitor just incompatible with this adapter?
Sounds like someone else is having this issue too, right?

No sound using SiS soundcard and ALSA

I've installed alsa using pacman, unmuted all channels using alsamixer and added myself to the 'audio' group following the instructions here: http://wiki.archlinux.org/index.php/ALSA_Setup
Unfortunately still no sound, I'm new to Arch and completely out of ideas. I've attached any info I thought might be useful but just ask if you need anything else posting. Please help me out as my laptop is my only source of music while I'm home over Christmas! Show some Christmas charity to a newb and Santa might not bring you coal!

[SOLVED]No sound on new i686 install with ALSA using SB Audigy 2 ZS

Previously posted at https://bbs.archlinux.org/viewtopic.php?id=146400
I replaced Xubuntu 12.04 on my 32bit legacy workstation which uses an Audigy 2 ZS soundcard (emu10k1) and analog outputs to a 5.1 amplified speaker set.
The old reliable "speaker-test -c2" produces no sound.
I use QasMixer and a screenshot of it's prior settings is at http://i.stack.imgur.com/h4vOe.png/ and the Arch setting are here http://img826.imageshack.us/img826/532/qasmixer.png
The ALSA information script is at http://pastebin.com/iRJamGBK. Note that is was run without USB microphone attached & with the mobo sound disabled in the BIOS.
I have been using the ALSA Wiki https://wiki.archlinux.org/index.php/Alsa and everything seems to check out.
I know the sound system is working because it works in the dual-boot WinXP. It also produces an audible "thump" when unmuting Analog C with alsamixer.
I am perplexed and looking for suggestions.
Also here is the termout as suggested by Arch Wiki AKSA… ‥ .

Ok - this is getting weird.
After doing some other stuff regards to networking, I tried the alsamixer again.
...and the default soudcard was changed to the USB microphone?
Now there were no changes to hardware, not even reseating PCI cards. The only change to the BIOS was, after booting from a CD using the BIOS boot menu (F12), the BIOS reset the hard disk boot order to its default (a non bootable drive) and I had to go into the BIOS to set the boot disk to the one with the boot loader.
So I ran aplay -l, and now the card is at 1 vice 2?
...so I edit ~/.asoundrc & /etc/asound.conf to match this, restart alsa, and now alsamixer shows the audigy card as the default.
But still zilch from speaker-test.
$ aplay -l

Apple ADC to DVI Adapter -- Power Brick gets HOT

Hello all,
I just purchased an Apple ADC to DVI adapter to connect my 23" Cinema Display to my new Mac Pro. It works perfectly, but I've noticed that the white, square power brick is generating quite a bit of heat. It feels sort of OK (within tolerance) at the edges but toward the middle it's noticeably hot. Not hot enough to burn my hands, or cook an egg, but definitely toasty warm. Is this normal? Or does it sound like I have a defective one?

If by "on" you mean the adapter is connected to your display and plugged in to an AC outlet, and you have an image on your display coming from your computer, then it's not dead.

DVI & ADC video card upgrade???

What can I get to replace the stock 64mb AGP card (at least I think it is) in my MDD Dual 1.42 machine. I currently run two Acrylic Cinema Displays, a 20" via DVI and a 17" via ADC...
Is ADC going to limit my options? If so, I can use a second ADC-DVI for the 17" monitor.
Any help would be great.
Thanx

Okay, so it sounds like I should "dump" the ADC idea.
Then an I looking for a card with 2-DVI or 1-DVI and 1-VGA ???
I've followed several of your discussions, but still need a little help with the Video Card upgrade education. Flashed cards kind of scare me, but are they okay to use? I don't know if I could tell the difference anyway. Asking a seller on eBay if it is in most cases won't get you anywhere either.
You've talked about the 7800gs card. Any others I could consider? I've read that some cards don't work in a FW800 MDD machine.

No sound except Flash, volume control doesn't work for that.

My sound seems to be cursed. Everything else works fine for me, but in the few years I've been using Arch I've been plagued by constant sound problems. Apparently something in a recent update broke my sound. I get no sound for anything but Flash, except Flash sound is SUPER LOUD, and doesn't adjust with the volume control. Everything else, there's just no sound. Not in VLC, Amarok, Battle for Wesnoth, or other various programs I tried. I tried VLC using the default sound output, the pulse output, and even the ALSA output just for the heck of it. No dice. I was reading in another similar topic that KDE might be the culprit, and indeed I'm using Pulse and KDE. My asound.conf is the default one that comes with the pulseaudio-alsa package. I've tried both gstreamer and xine as backends, they both have the same problem. In pavucontrol, it looks like sound is playing. If I play music or a test sound, the sound bar moves, but you still can't hear anything.
Now here's where it gets weird. Selecting a device within Phonon is screwy. In the output section, the devices listed are as follows. All but the top one are grayed out.
Internal Audio Digital Stereo (IEC958)
Internal Audio Digital Stereo
Dummy Output
Internal Audio Analog Surround 4.1
Internal Audio Analog Surround 4.0
Now, in the audio capture section, the devices are different.
Internal Audio Analog Stereo
NVidia CK804 with ALC655 (NVidia CK804)
NVidia CK804 with ALC655 (NVidia CK804 - MIC ADC)
Pulse Audio
In that list, pulse is greyed out. Are they supposed to be different like that?
In any case... I'm at a bit of a loss. I just can't seem to keep the sound working on this thing. Any ideas?

I think I encountered the sound problem too. I'm using a thinkpad T42, installed gnome, using ALSA. Normally I just enter runlevel 3 into the console, I have ALSA configed and the soundcard is well recognized. But when I play .mp3 using mpg123, everything goes fine but just no sound output (I setted up alsamixer previously, and had all necessary channels unmuted.). That goes several days. And one day, after setting up alsamixer, I also did a alsactl -f /var/lib/alsa/asound.status store, miracle the sound is there. But the day after, the sound disappeared again. Now I'm totally lost, leaving me thinking whether it's a Arch sound bug?
By the way, my system is most updated and upgraded.

Acquiring 24-bit sound with a third-party sound card... truncation issues.

I am having a very strange problem when using LabVIEW to acquire audio
data via the Windows API from a Creative Professional E-MU 1616m sound
card. The goal is to acquire sound in 24-bit resolution.
When capturing sound in 16-bit mode (as set in the LabVIEW software),
the E-MU 1616m behaves as expected, with a 105dB SNR and approximately
-130dB noise floor, after dithering. However, when switching to
24-bit capture mode, a very severe truncation occurs. This sends
the harmonic distortion and noise through the roof. After
investigating fairly deeply in our LabVIEW code, I am wondering what
might be the problem.
I have compiled a number of screenshots which showcase the problem in more detail.
Here is a background of the experiment:
For these tests, both the analog and digital audio was generated by an
Audio Precision System Two system, and was passed directly into the
respective line-level or digital audio inputs. Digital audio was
tested using both coax and optical cable. In the sound card
control software, the audio was sent directly from the input channel
into the WAVE IN L/R (via the Windows API, I assume). The
sampling rate for the profile was 96kHz.
The sampling rate in all LabVIEW functions was set to 96kHz. The sample rate set in the AP Digital generator was 96kHz.
ANALOG 20dBu 96kHz 16bit.jpg
In this test, everything looks fine. The audio input is at
Full-scale for the E-mu's ADCs. It is exhibiting expected 16-bit
performance (with dithering).
ANALOG 20dBu 96kHz 24bit.jpg
Now we instruct the driver to capture sound in 24 bits. Notice
that the noise floor and THD+N go up considerably. Effects of
truncation become visible on the time-domain display.
ANALOG -20dBu 96kHz 16bit.jpg
Now we drop the input level to -20dBu. The performance
starts to look a little messy but is still acceptable. Note,
however, the high peaks on the odd harmonics.
ANALOG -20dBu 96kHz 24bit.jpg
Now we try to capture at 24 bits. The effects of truncation are extreme at this low signal level.
ANALOG -60dBu 96kHz 16bit.jpg
Now we are at extremely low signal levels. Individual
quantization levels can be seen on the signal. Dither is also
present. Performance is still good.
ANALOG -60dBu 96kHz 24bit.jpg
However, when increasing the resolution to 24 (which should increase
the number of quantization levels), our signal is reduced to a square
wave. Obviously something is wrong.
DIGITAL 0dB 16bit 96kHz 16bit.jpg
Now on to the digital tests. We start with full-scale. We
used an AP outputting a properly dithered 16-bit signal over an optical
cable. The soundcard is instructed to receive in 16 bit
mode. It looks good.
DIGITAL 0dB 16bit 96kHz 24bit.jpg
Using the same input, we change to 24 bit receive mode.
DIGITAL 0dB 24bit 96kHz 16bit.jpg
Now we set up the AP to output a properly dithered 24-bit signal at
full-scale. The dips in the frequency domain show us that
something is wrong.
DIGITAL 0dB 24bit 96kHz 24bit.jpg
Receiving in 24-bit mode. Same story as before.
DIGITAL -90dB 16bit 96kHz 16bit.jpg
Now we decrease the amplitude to a low level. Well-implemented dither is shown here clearly.
DIGITAL -90dB 16bit 96kHz 24bit.jpg
However, receiving in 24-bit mode reduces the signal to a dithered square wave.
DIGITAL -90dB 24bit 96kHz 16bit.jpg
Here is the low-level signal with the AP generating a 24-bit
signal. Dither is applied, but vanishes in the e-mu 1616m.
It seems the dither level has been changed. This is the cause of
our dips from before.
DIGITAL -90dB 24bit 96kHz 24bit.jpg
And finally, we transmit and receive in 24-bits. Here are the results.
We have achieved similar results using several of your breakout boxes and soundcards.
Attached are all screenshots, as well as the main VI (AP Test.vi) and
the dependent vi's. There are a number of SVT vi's in the
project, but they can be ignored since they are not related to the
problem.
Any help would be greatly appreciated.
Best Regards,
Brett Gildersleeve

Hi Brett,
I took a look at the code you attached, but it appears that you may have left out the subvi that actually acquires the sound. When you say Windows API, I assume that you are calling a DLL at some point. How are you configuring the inputs (or what function are you using)? It could be (and this is just a guess) that when you specify 24 bits, the DLL returns the data in a very specific format. If you don't interpret the bits that are returned correctly, LabVIEW may not know what to do with them, as LabVIEW does not have a native 24-bit datatype. If there is any documentation for these function calls, our answer might there...
Just some thoughts -- thanks for posting your solution!

I can hear sound on headphones, but not on laptop speakers (stereo)

I have been installing my audio on my Arch Linux and i am currently stucked here.
When i check if my modules are properly loaded i get this outputs which
in both cases indicates that my modules had been auto detected:
http://shrani.si/f/1/Dr/3VA6qi6K/outputs.png
But when i hit command:
speaker-test -c 2
i get no output from speakers. The weird part is if i plug in my headphones
i can hear the sound from left and right which is what i should allso hear on
speakers.
Here is allso an alsamixer where i ve unmuted everything:
http://shrani.si/f/2L/TD/2SRoXaY/outputalsamixer.png
What could be wrong?

Connecting Superlogics ADC-1 I/O Module with third-party VI

I'm having trouble using the LabView driver for the ADC-1. It gives me the error "Resource not found" when I run the VI "ADC-1 Main.vi".

Hi,
It sounds like you are giving the driver the wrong VISA resource string. Make sure that the string is correct and try again. You should be able to check this in MAX.
Hope this helps out!

X800xt vga or 9800xt pro adc+dvi ?

Hi
Yesterday, I received a second hand X800XT that I plugged in my PowerMac (2x2GHz). First deception, it had a DVI and a VGA port, not a DVI+ADC as the 9600 I used to have until then.
I worked a moment but never could get a DVI signal. I however got an expected 1600x1200 through the VGA port. Seemed responsive using Aperture but it'd have to be recalibrated.
The seller confirmed me that this very card can only feed 2 VGA monitors, no DVI.
He proposed me to swap my X800XT for a 9800XT with the expected port and 256MB of VRAM.
So, my question is:
As I work primarily with Final Cut Studio and Aperture, what's better for me:
1) To keep the X800XT and feed 2 VGA (LCD) monitors with it?
2) To go for the 9800XT
3) to just forget about that and keep my 9600 1st gen with 64MB which at least could decently feed both of my ADC and DVI monitors but not quick enough to work in real time with Motion or Aperture?
I really need help here, thanks in advance.

Hi
I've seen some X800XTs on eBay which are PC cards flashed with the Mac ROM. These happened to explicitly state the DVI port was only functional as a second analogue VGA port using an adpater (supplied). It sounds as if the card you received is also a flashed PC version.
The 'official' Mac version has a DVI and ADC port (both fully functional). It's fairly expensive in comparison though and Mac compatible ATI cards in general seem to be in short supply at the moment.
If you've already got two digital DVI or ADC monitors, I'd personally be reluctant to switch to analogue VGA which would be a backwards step. I guess a fourth option, return the card and buy the official Mac version when available would be the best solution, budget permitting.
