• How to change the DAQmx sampling frequency

  Hello

  I'm trying to: record streaming channels (acceleration 21 and 1 tension) using a DAQmx task, then convert the data to a PDM file. The program files and output to the TDMS file very well. The issue I'm having is that I can't change the sampling frequency. I want to record 500samples/s and I can not get the "real sampling rate" of change of 1651.61samples / s. I am trying to use the clock to do this and I succumbed. I also tried to change the settings of "Timing" in the task without a bit of luck. Here is a screenshot of the .VI I created. I've also attached a copy of the file VI. Any help would be greatly appreciated!

  

  Thank you

  Tony

  You will need to provide the model of your device. You can also look in the sheet/manual to see what the real supported sampling rates. Some devices have limited rates.

• I am facing problem with playback of the audio recorded.

  Original title: sound recording problem

  Use built in mic, I recorded w/vocals/guitar,... and playback starts well, but after a few seconds the sound loses the basis... or low frequencies.

  It is uniform everytime I try. What I am doing wrong?

  Hello

  What version of the Windows operating system is installed on your computer?

  If I understand correctly you are facing some problem with the audio recorded. There is no way to lose the sound after a few seconds; There seems to be a problem with the registration. I suggest you to run the game audio recording Fixit then try to register once more and check if it works.

• How to change the audio output for the metronome

  Hello

  I would like to send the metronome (and speech signals) for monitors to the scene in the ear.

  I understand that I can do this in MainStage using different output for the above titles vs. the rest of the 'Concert '.

  I tried to follow the instructions of the Manual:

  Change the audio output for the sound of the metronome

  1. Choose the MainStage > Preferences > General.
  2. In the section of metronome on the general tab, choose another audio output on the shortcut menu to exit.

  PROBLEM

  1. on the general tab, only the outputs 1-2 are available/selectable (likely, these are also by default for all "Concert")

  2. Why is this process in the manual if it is not executable (without doing something to another additional Set up)?

  3. it's probably among the requirements of setting up more critical even easier for using MainStage with a live band, so why am I having to ask for help at all!

  Rant on (its been a long day)

  Grateful for any help to solve cela. I guess I can send the metronome (such as a click track) and speech signals on the same outputs, which are separated from the rest of the Concert... or should I change the outputs on the other tracks and keep the outputs 1-2 for the metronome marks / voice?

  Thanks in advance for all advice and my apologies for my frustration. JM

  To access the output audio, you need an audio interface with several outputs.

  Someone knows how to fix this?

  Hello, DuFF1

  You can have only one default device.

  It is not possible to put two devices by default, nor is it possible to configure the output in default Media Center device. You can try searching for additional Media Center change the audio device by default or continue editing the device default manually before watching TV on the Internet.

• Select the audio recording device

  I have inspiron 1501 (a new replacement), with 32-bit amd anthlon, windows vista OS.

  My micro phone volume was very low, the person on the voice chat could not hear it. I tried to make it work properly, by mistake, I disabled the device for registration of the properties. now I don't know how to re - activate again. It gives the message that no audio device is installed. I think by the upgrade of a link to forums to dell than the old problem will be over, but I do not know where to install the audio recording device. I tried the installation of equipment as well, but did not work.

• Change the audio level of many clips in the browser?

  I have 1000 or more clips in these images of GoPro project, cameras, and selects music, with many clips that have audio very strong especially the GoPro mounted on the vehicles off the road as they motor at high speed through obstacles. My edit in place includes 20/20 speakers, and even though I have a moderate level of audio that is configured for editing when I select images in the browser that has strong audio I need to stop and lower this clip in the browser at once and he eats a precious time.

  Is it possible to change the audio level in many clips selected in the browser?

  Select the clips.

  Go to the Clip > Audio Options > Audio Gain

  When the Gain Audio pane opens, set Adjust Gain of: -12

  

  Click OK. You can experiment on a clip or two to see if this gain reduction is too much or not enough for you.

  My recent post ('start failure after firefox 12.0...') has been marked as a post on Firefox 3.6, but it was a post about a problem with Firefox 12.0. My problem is that Firefox 12.0 would not start once it has been installed. I had to re - install Firefox 3.6 to write the post. Now, the message is marked as a pole of Firefox 3.6. The same problem occurred last month when updating Firefox 11. I would like to remove the current tags and replace them with Firefox 12.0.

• How can I change the ID for my poster?

  Hello everyone. I'm changing the ID on my poster to determine who is my 'PC' view and that is my 'second' screen. My current setup is an Acer H243H monitor and a LG TV. The monitor is connected via DVI and the TV is connected via HDMI. The screens are connected to a NVIDIA GTX 660.

  Currently, even if I have my monitor set as my main/main screen, it appears as ID #2 in the Control Panel, and when I press the Windows and P key, it's my second 'screen '. If I press the Windows and P and choose 'PC screen' only it displays only for me TV. It is the exact opposite of what I want. I want that my monitor to set as the ID #1 so that it can be defined as "the screen of my PC. Does anyone know how to do this?
  Before someone asks, my drivers are all up to this date, I tried to change which monitor is my main screen, etc. It did make a difference.

• On the audio recording problems

  Hi all

  I have a problem with regard to save audio files in Labview.

  In my program, I acquire the audio signals of the soundcard of the PC constantly and save them in a queue. After that certain prerequisites are activated, these audio signals in the queue is stored in a .wav file. This program works well, except a problem, which is the time lag in this .wav file. For example, I save a sound segment for about 30 seconds, but after the backup, this .wav file is just 21 long s. It contains all of the original recorded segment, but the time axis is compressed, which sounds like played fast. I searched all day and could not find any information about it.

  These sounds record and save functions are part of a comprehensive program, and I'm sorry that I can't give a single vi on it. I add the numbers below and I hope it helps. I am also willing to provide any additional information.

  PS: I have reviewed the incompatibility caused by approximation of the "t0" (published in http://forums.ni.com/t5/LabVIEW/Time-mismatch-with-Sound-Input-Read-VI/td-p/1385404 ) and compensate for that during the savings phase. (see figure 2)

  Thank you very much for the help!

  

  

  Hi, Vans,

  Thank you for your response.

  For your questions.

  1. I'm using Labview 2011 sp1 on Windows 7/Xp. I tested the program on desktop computers and laptops. I don't know about the types of sound card, but given that this problem occurs on several different computers, I think that this is not the problem of sound cards.

  2. for the sound card sampling frequency, in fact I checked that. I read signals of waveform of the 'read.vi of sound entry' and the term 'dt' is equal to 1 on the sampling frequency. So I think that the sampling rate of the sound card is correct.

  In fact I have just solved this problem by myself, but the solution is pretty weird. I think there are two reasons that caused this problem.

  1. when I receive tones of "read.vi of sound input", I first save them in a queue. Once the acquisition is completed, I save all the signals in the queue to a .wav file. But I'm going to do to overcome the overlapping sound and the gap caused by the "t0" reconciliation, a waveform signal re - organize before saving it, as below. According to my knowledge, I think that this 'dt' in the resulting waveform (indicated by the arrow) must be the same as before, but in fact it is not, and it becomes 1.

  

  2. Thus, to solve the first problem, I manually change the term "dt" once again as below. After the change, I'm sure that the "dt" is back to the correct value. But then is the strange thing is I saved the same signal waveform in two different ways, using "his write.vi file" and "file its writing simple.vi" respectively. The first method is the one I have used before and it caused the problem I posted here. The second works. In my program, I put as 16 kHz, 16 bits/sample, and 1-channel sampling rate. The file .wav from the first method has a strange flow 705 bps and the wave from the second method file has the right bitrate which is 256 bits/s.

  

  I tested the program of hundreds of times and each time he acted like I described above. I don't know if anyone has ever faced the same problem as me, but I hope that my solution can be useful for others. And I also hope to be useful to improve your LabView products.

  Thank you for your time.

  Best regards
