Setting NI5641R ADC input level

Hi,
I am using a NI5641R board and I am programming it using the LabVIEW FPGA Module.
How can I set the maximum input level of the ADCs?
Concerning the DACs, there is a VI to set the maximum output level in the library that comes with the board.
Isn't there anything equivalent for the ADCs?
Thank you

Probably, I have found the solution.
I post it for those who are interested. Of course, comments are welcome.
IQ rate at the output of the ADC (downconversion):
- use "ni5640R ADC Configure NCO.vi" VI to configure the sampling frequency (e.g. sample frequency= 100 MHz);
- use "ni5640R ADC Configure DDC.vi" VI to configure the decimation (e.g. decimation=4);
- than, the resulting IQ rate is: sampling frequency/decimation (e.g. 100/4=25).
IQ rate at the input of the DAC (upconversion):
- use "ni5640R DAC Configure for Quadrature Mode.vi" VI to configure the CIC Interpolation Factor (remember that there is an addictional fixed interpolation factor of 4);
- than, the resulting IQ rate is:: 200M/(4*CIC Interpolation Factor).

How can I set the microphone input level?

How can I set the microphone input level?

It would be best to use the standard windows mixer "sndvol32.exe" (in the windows directory) and control it with the System Exec.vi from the Communication palette.

Set audio input level manually on t5i

First post here. I've just started workig with my new t5i, which I'm using to work on my ongoing video tutorial series. In the manual I see how it is possible to set the audio input level maually for an external mic but I can't figure out how to navigate to the menu that allows me to do this. I have pored over the user manual a number of times and can't find this information. Can anyone help?
Solved!
Go to Solution.

Same camera in different shooting modes. The menus I described would be for shooting video in "P, Tv, Av, or M". Anything else will give you a smaller menu selection like you have already seen.

Setting Input Level with Griffin iMic

I'm trying to digitize an audio cassette with Soundtrack Pro. My setup includes a Griffin iMic that goes to a USB port. The trouble I'm having is in controlling the input volume. The level meters indicate clipping, but I'm not clear how to set the input level.
If it's in the Recording tab (>Input) with the Gain slider, mine is greyed out.

M Wohlgy,
(I know this is months after your post.)
Control of the iMic volume is in the Preferences pane called "Sound". You can set the output and the input levels there.
Remember the iMic's position switch works only for the imput, either close to the microphone icon for "microphone" or away from it for "line in".
I use the iMic exclusively.

Setting input level when recording

Is there a way to set the input level in Audition when recording? I can't seem to find it if it's there.
Here's the setup: Audition is installed on a new Dell Vostro (plenty of RAM and speed) with an M-Audio Delta 1010 LT card. The input is coming directly from a broadcast console at a radio station. Audition is used to record incoming phone calls along with the DJ's mic for playback later: DJ mic on left channel, incoming call on right channel.
Broadcast consoles are different beasts from recording consoles. The input channels of a broadcast console do not have variable/selectable pads or gain... so the audio signal is fairly hot.
The 1010 LT card has a "control panel mixer" but it seems to have no affect whatsoever on the input level. As a result, the signal clips when it's recorded into Audition.
So... is there a way to set the input level in Audition when recording?

If you are using a soundcard with input from pro console you need one that accepts pro levels I'm afraid! You will need to attenuate the input to the Delta 1010 by some external means like inline 10 - 14dB attenuators for instance.

Can you use applescript to access the volume setting "input level" in system preferences?

I want to make a script that adjusts the output volume of my mac based on the volume that the mic hears. I am not very good with applescript, but I do know how to control the volume. I was wondering if there was a command that retrieved the input level from the mic as it is show in the sound preferences in the system preferences window. Any help would be greatly appreciated.
Thanks

Does the following script do what you are asking for?
get volume settings
set theInput to input volume of result
set volume output volume theInput

How to Set Input Levels with FirePod and GarageBand

Hello ....
I/ve got Garageband and my Firepod 8 channel interface working ... but I need some tips .. especially on the relationship of input levels between my Firepod and Garageband ....
When I am setting input levels for a recording ... where should the input level be on the track in Garageband? .... Is that volume setting only for playback and mixing? .... or is it for the input as well ...
Thank you ....

Where should the initial input levels be set? ... Would you use the loudest
part of the song to do this? ...
Yes, as loud as possible without lighting the FP's clip leds.
When I mix the final product ... and change the volumes on the different
tracks.. aren't you then changing the input levels?
No, you're changing the output levels.
can't you red line and overload the track?
Yes, that's why each track has a fader, so that you don't clip.
Is there a master ouput level indicator
Yes, right over the Master Volume slider.
I guess you can't just put each track as loud as you want ... correct?
As loud as you want without clipping.
I would strongly suggest doing some web searches on "Mixing and Mastering" to learn more about how to mix, there's a TON of info floating around the web.

ADF Faces: How do I set values for input controls in an af:table

Use case: user enters master/detail information into an input form using an af:table for the desired number of detail rows.
I have an ADF Faces input form with master level input controls, and an af:table (bound to a backing bean CoreTable) for the detail data set.
The input controls are value bound to updateable view objects built from entity objects, with the appropriate view links providing master/detail iterators.
Once the user has entered the master keys (via inputTexts, and selectOneChoices), I create a row in the detail VO, thus creating a visible blank row in the af:table.
The user then completes the key for the detail row (in the af:table) by selecting a value in a selectOneChoice (in a af:column) with autoSubmit on and a valueChangeListener that sets the VO row attribute with the new value.
The user then continues to enter into the remaining inputTexts and selectOneChoices in the af:columns until all values have been entered.
I do not have autoSubmit on for any input controls in the af:columns other than the key, for performance improvement.
The user can then use a command button (which has an action method) to create another row in the af:table.
But, (in the action method) I need to set the values for the 1st detail VO row attributes, from the input controls, before creating another row.
The input controls are bound to backing bean CoreInputText and CoreSelectOneChoice objects, and they have not set their values at this point, even though I have partialSubmit on for the "New Row" command button.
I do not value bind the input controls in the af:columns to the backing bean objects, because we need to display data for all rows entered into the af:table.
Any advice on the best way to perform this operation would be very appreciated!!!!

Thanks for the reply Steve!!
Yes, I followed the techniques in Screencast#7, and it works great in my edit page.
But I am having problems with my input form.
I actually have master/detail/detail relationship for which I am creating an input form.
I created the input form as a copy of the edit form, and am making revisions as necessary.
I created new view objects for the input form (from my three entity objects), which have the "Tuning" set to retrieve "No Rows (i.e. used only for inserting new rows)"
I added an invokeAction that binds the "CreateInsert" action on the master iterator, so when the page is first displayed, the master level controls are available for data entry (as in 13.6.2 in the Developers Guide): but the first level detail controls are not rendered, and the af:table (for the second level detail) is rendered but with no rows.
Once the user enters key values for the master (a three part key), I manually create a first level detail row by executing the "CreateInsert" action binding for the first level detail iterator.
Continuing on, the user then enters a key value for the first level detail I manually create a second level detail row using it's "CreateInsert" action binding.
Now the user has a form with all master and first level detail controls completed and one empty row in the af:table for it's first entry.
The key column in the af:table has autoSubmit on, and an value change listener. That listener uses it's getNewValue() to set the key value ("locationCode" in this case) using
setLocationCode from the ViewRowImpl. Here is that value change listener:
public void locationChanged(ValueChangeEvent event) {
if (null != event.getNewValue()) {
LocObsCreateViewRowImpl locCreateRow = (LocObsCreateViewRowImpl)appMod.findViewObject("LocObsCreateView").getCurrentRow();
if (null == locCreateRow.getLocationCode()) {
locCreateRow.setLocationCode(event.getNewValue().toString());
Now comes my problem: once they have entered the values in the remaining columns, they can use a command button to create another row in the 2nd detail iterator, thus creating another visible empty row in the af:table. But the values from the first row (other than the key column) are not assigned to the row in the collection and I can't figure out how to set values in the collection's row.
I imagine I'm missing something using bindings and the Request Processing Lifecycle, and after reading this I can see how much manual work is going on.
The users have specified the need to have all information available on one page, so I've designed it so they can insert and iterate through the first level detail collection.
They have also asked to not use the mouse; they are looking for a "heads-down-data-entry" system.
Again, I really appreciate any advice you could give.

FaceTime limits the input level of the internal mic, FaceTime limits the input level of the internal mic

Input level - meter?

This might seem like a stupid question, but I need to ask it as the GB help doesn't explain it clearly. Where should one set input level for recording and where does one MONITOR that level via a meter reading (to check for clipping, etc)? This seems like such a basic need, so I'm confused to why it's not clearer.
I'm using an M-Audio FW410 which has it's own software mixer, but from their manual it seems the input level should be set from within GB.
I've experimented with the Recording Level slider in GB and even when it's not greyed out I'm not hearing a difference in signal, even if I turn it to 0. Do I actually have to go to the Sound control panel in System Preferences for this? I should mention I'm recording a "real instrument" track and my signal is coming through loud and clear.
The only two level meters I see from within GB are for each track's volume (which is just for mixing and/or monitoring while recording, correct?) and the master volume slider/meter at the bottom.
thanks,
Scott

The meter on each input should be reading at a sensible level: not over-peaking but not too low either. The main control has no effect on these levels, only on the final mix. For example, if the main control was at a normal setting, and you had a number of channels all at a high level, then they would add together and you would need to bring the final level down to prevent it over-peaking. The level should be set sensible at every stage.
You set the input in the GarageBand Preferences, so this will show what you are using. If you have your interface selected then the internal mic is not in use.

Can't adjust input level when using usb microphone

Hey guys,
I'm very familiar with this version of Garageband, and just started using a Blue Snowball USB mic. When I plug it in and set the drivers accordingly, the input volume slider is greyed out, making it inaccessible. Is there a trick to being able to adjust input volume?

Option Click on the Volume slider icon in the menu bar and choose Sound Preferences. Choose the interface and you should be able to see the input level.

Input level meter not working in multitrack

Wanted to see if anyone could help with this problem. This problem has persisted in 5.5 and now 6. My input levels work fine in wave editor but not in multitrack. When I try to right click it's greyed out. Im a vo artist so my setup is pretty straight forward.
I'm going from my Shure ksm 32 mic to an Art voice channel preamp which then goes via usb to my Macbook Pro. I record in mono...my input is the codex for my mic and my output is default because im listening thru my macs output on my headphones. The small signal meter in the track works but not the big one I use to monitor my level. As I stated when I bring into waveform it works fine. What's annoying is that it worked for like 5 minutes but I can not get it to work now to save my life. I've tried switching up the inputs and outputs but nothing helps.
Any help would be greatly appreciated. Thanks

I use a PC not Mac so can't be sure things work the same, but try hitting the "Monitor Input" (the capital I button) in the track control area at the lest hand end of the track. On mine this switches the big main meters to monitor the input to any track(s) set this way.

How to adjust Garageband real instrument input level

Hello,
I am using an electric ukulele with a B-Band pickup/pre-amp and a Lightsnake USB instrument cable to connect to my MacBook and Garageband 2009. The B-Band pickup does not have a switch or volume control for the pre-amp. I have both the input levels in system preferences and Garageband set to the lowest setting, but the input signal is too strong, so it goes into the red zone on the input level for the track, causing digital clipping and unwanted distortion.
My question is, is there a way to lower the input signal even further? Maybe some hidden setting/option, or a software download? Any suggestions are welcome.
Thanks,
jwebb13

I have never before seen the Lightsnake USB that you have, so I can't comment on that. Perhaps see if there is a driver update for the Mac? I notice there is none on their webpage www.sountech.com/downloads/drivers but I'd see if there is something happening there soon.
I have had good success with a Presonus Firebox project 10. It has heaps of inputs, and uses firewire as its interface to the mac. There is a smaller 2 main input version if you are budget conscious.
The Presonus range have great pre-amps in the inputs and give greater control over the input levels. Plus you only need a guitar lead or mic lead. Plus it allows you to plug any pickup/electric instrument or microphone into it.

Help : input level too low in Logic from studioKonnekt 48

I tried to record and use some voice microphone and some guitars (telecatser, some preamplified acoustic flattop, some archtops with humbucker or P90...)with Logic and SK 48 TC near.
If the voice setting with the gain trim at 12 were OK or even tooo loud, I NEVER succeeded to raise a level higher (lower..) than - 30 Db and this with the gain trip at the maximum and the main output at the maximum level...This dosen't allow me to work properly. I've tried different entries (1 to 4) than the line inputs and so on..
TC wrote me that they have -62 db in preamp but I could not succeed to raise a workable level.
Situation is quite different when I use a guitar pream (Radial PZ-Pre) or a Para acoustic DI from LR bagss.
Today, I've tried with a bass direct into SK 48, trough the preamp ...but the signal in Logic stayed absolutely loww while the screen indicator of the SK48 hardware showed me enough gain (orange to red)
I a not expert in both audioinyterfaces and Logic. I do not find in Logic how to increase the input gain from the audio interface...
Any help would be more than appreciated...since I have spent days and days to undertsnad and try...and finally I did not record anything since I have this new gears..So, I feel disapointed..
Ciao
Chris

+"I do not find in Logic how to increase the input gain from the audio interface..."+
You don't (apart from the level fader of the Record Track, of course).
You can adjust input levels in +Audio MIDI Setup,+ but when I suggested checking there you replied: +"Thanks a lot, but everything is weel set up ???"+
So you need to look at the software that controls your interface.

Input level meter in Audition CS5.5

I can't find an input level meter in audition CS5.5. I have to go my windows 7 control panel find me device and set the levels. So, to set levels I have to have two windows open, one control panel audio adjustment window and one soundbooth window where I actually record and watch meter, then I erase and record for real.
I must be overlooking something -- every other audio program I have ever used lets you set input levels while watching the meter. I've been through the help, and Googled it and I can't figure it out. In Audition, how do I set input levels from within Audition CS5.5 (not in windows 7 control panel)?
Thanks!

Short answer, no!
Audition merely records EXACTLY what the input device is sending to it. In normal useage the "level" of the signal to be recorded would be set externally, e.g. by use of an audio mixer or a "gain" control on the input device. I assume you are recording by using a line or mic plugged straight to your computer? In which case, the Windows Audio Control Panel is the only way to set levels.
