Drop the sample rate

I'm trying to drop the hardware sample rate. It's at 44800Hz. When I want to capture audio through my Audigy 2 soundcard at 44100Hz I get the message "We do not support recording when your file does noyt match your hardware sample rate. Your current hardware sample rate is: 48000Hz."
Edit -> Adjust Sample Rate does nothing.
Edit -> Hardware Audio Setup shows a 48000Hz sample rate but I can't change it.
Oh. Is there a "global" reset on settings?
Thanks
Gis

My very strong advice to you is not even to try. Audigy soundcards work internally at 48k, regardless of what you tell them - the internal architecture is fixed. If you tell them to work at 44.1k, then all they do is 'spoof' the output by doing an internal sample rate conversion on the fly. The problem with this is that it's not a very good conversion - and Audition can do it rather better. So the way to go is to record at 48k, and then do the conversion rather more transparently in Audition. Doesn't take long, and won't degrade the sound even more than the card already has. So...
...a better way to go would be to ditch that pile of Creative rubbish and get a proper soundcard!

  • Why cant I control the sample rate?

    I am sure there is a simple programming answer to this but I am drawing a blank. I would like to slow down my sample rate in the following block diagram, however changing the sample rate at my Sample Clock seems to have no effect. Any ideas? Thanks in advance for your help

    I recommend the Wait (ms) function over a timed loop unless you specifically need the timed loop behavior.  I just learned today (looking up something related to a different thread): "Each timed structure on the block diagram creates and runs in its own execution system that contains a single thread, so no parallel tasks can occur."  In a regular while loop, tasks can run in parallel.

Then i got the new iphone 5s i restored ot from icloud from my previous iphone 5.  Now everything works find execept now the games are slowy and drops the frame rate and look choppy. Then i restarted my iphone 5s as a new device downloaded the same apps even the ones optimized for ios 7 and the games still lag. And i just got my iphone 5s replace.  The funny thing is.  While im playing games and their running choppy and slow and if i take a snap shot inside the phone. They run smooth and HD but just for a few seconds and boom they go back to slow and choppy.  Is it the ios 7 or the iphone 5s it self? Like i said this is my replacement iphone 5s because the other 5s did the same thing. And it was running slowly.

    As far as I know you can't delete the primary email address for an iCloud account.  It's assigned when the account is created.  But your neighbor wouldn't have been able to get into your iCloud account without your Apple ID and password.  Are you sure the account wasn't still on your phone when you gave it to him?
    You could migrate a copy of your data to a new iCloud account but I would still be concerned that someone else was using my old account, which presumably still has your data in it.
    I'm fairly certain that you're going to have to have iCloud support help you sort this one out as they may have the ability to make changes to an existing account that users can't.  Make an appointment with the genius bar at a nearby Apple store and have them take a look at it.  If necessary, they should be able to contact iCloud support for you.

  • IPhone: AudioQueue - is it possible to change the sample rate?

    I've been playing around with the AudioQueue stuff for a few days and it's all working fine.
    I was trying to build a low-latency playback system by making the streaming buffers the same size as the audio file and pre-loading the buffers (which works fine) but I've hit a snag.
    I've been trying to get the streaming to work at different sample rates so that I can play back the same sample at different pitches. I managed to do it by modifying the sample rate in the AudioStreamBasicDescription structure but in order to actually make the stream playback at the new rate it seems you have to create a new output, reload the audio file into the buffers and re-enqueue the output queue before starting playback again, otherwise the sample rate change has no effect.
    There is a method to set queue properties; AudoQueueSetProperty() but unfortunately the sample rate Property (kAudioQueueDeviceProperty_SampleRate) is read-only
    Can anyone suggest a way to achieve this with AudioQueue or do I need to move over to OpenAL?
    Thanks,
    Neil

    Dan,
    there is one point in your understanding, which i am not sure what you think about when talking about it: I understand E-series devices do not support this property change while the VI is running.
    infact, you cannot change the sample clock rate during acquisition. but
    this does not mean that you cannot change it while the VI is running.
    you have only to interrupt the acquisition. since you want to acquire
    continuous, this would have the same effect as stopping the vi, i asume.
    so the best way to accomplish this task is to use an external clock.
    this is e.g. often used for acquistion on rotating shafts. the
    acquistionrate is always e.g. 24 points per revolution regardless of
    the rotational speed of the shaft, except for a maximum frequency of
    course.

  • How can I change the sample rate (delta X)?

    Hi, I create vi which can measure resistance, it will record the data and write to a file.
    however, I want to change the sample rate which is delta x. is that anyway I can do?
    I have try to put a clock inside the loop, it does slow down the speed but not the sampling rate.
    Please help me!!
    Thank you!

    Hello Shan405,
    Adjusting the Reading Rate of a DMM
    As noted in the above DeveloperZone article, there are a lot of factors contributing to a reading rate of a DMM. 'Sampling rate' can only be configured in digitizer mode, which can only be achieved on the flex DMMs
    Using the NI PXI-407x DMM as an Isolated Digitizer

  • The sample rate in my code is too low. Is there a way to make it run faster?

    Dear Sir,
        I am a LabVIEW customer, and just have a question about LabVIEW.
        We are running a code of "Wirebonder Project", but find the sample rate is too low. I'm wondering if there is a way to make it run faster. (I have
    attached the code here.)
        Thank you very much!

    Hi Xian,
    What system are you running this code on and are you using the LabVIEW Real-Time Module? There is a presentation online on Optimizing and Benchmarking Real-Time code with useful related links as well as other articles in the DevZone on things like Benchmarking an Application Using LabVIW Real-Time and DAQmx.
    As you can see, this is not a simple question, so take a look at the information in these links and see if you can narrow down what in your code is running slowly and how much you might be able to improve the speed.

  • Setting the sampling rate in SignalExpress

    I am using a cDAQ-9172 with a strain gauge module and a thermocouple module and using SignalExpress.  I want to acquire data at a pretty low frequency rate (2Hz), but I am unable to use 1 sample on demand in the acquisition setup.  I get the following error.
    Error -201087 occurred at DAQ Assistant
    Possible Reason(s):
    Measurements: Task contains physical channels on one or more devices that require you to specify the Sample Clock Rate.
    Specify a Sample Clock Rate.
    Device: cDAQ1
    I am unable to setup a sample clock rate as it is 'blacked' out by the software in the 1 sample on demand mode.
    When I try to use continuous or 'N' sample mode, the cDaq is sampling at a rate of around 1600 Hz, even though I am putting in a value of 1Hz on the seti[ screen.  The large amount of data will prevent me from downloading the data to Excel for further reporting.  I obviouisly don't need to sample my TC module at that rate either.   
    Is there anything I can 'easily' do to decrease the sampling rate down to a low level?  Everything I have tried doesn't seem to work and I don't really want to go away from SignalExpress.
    Jay 

    Hi Jay
    I am assuming that you are using the NI-9237.  This strain module has only a specific set of sampling rates.  If you specify a rate that is not supported it will corers the rate to the next higher sampling rate.  Also since you are using the cDAQ chassis, there is only sample clock so it must choose the highest sampling rate.  So it is not possible to sample at a lower rate.  Please see the following link.
     If you have access to LabVIEW then I would suggest taking your readings at the fast rate and then average the samples before you write them to your file.  The following link has some more information on this. 
    If you are limited to Signal Express, this task is tricky.  If you select a N-Sample acquisition, set the samples to read to greater than two, and set the post acquisition delay  under the execution control tab to 1000, you acquisition will acquire the two samples at the very fast rate, but it will wait 1000mS between each acquisition.  This will slow the overall sample rate.

  • What is the sample rate of voice memos?

    I often record lectures via Evernote audio notes on my iTouch.  I want to convert those audio files to text.  A piece of software named, MacSpeech Scribe has caught my eye.  A review states, "a minimum sampling rate of 11.025khz" is needed for the conversion.
    Does anyone know the sampling rate of an iTouch audio note?
    Thanks in advance.

    ok i've figured out the physics of this question.
    The Cache Read data rate is always larger than the Cache Write data rate, because the computer would have to be rendering to Cache faster than realtime for the Write rate to be higher, which would make it unnecessary to render to cache in the 1st place. So I'm really only worried about the Cache read data rate. Does adobe have a paper that tells us what the data rate is for different sequences.
    my 3 common workflows are
    canon h.264 1080 24p
    AVChd 1080 24p from my GH2 with a 44mb
    and
    r3d 5k epic footage 24p - (this is painful to edit )
    anyone know where this info is?

  • How to coerce the sampling rate??

    I think I found my problem with sampling rate.
    I'm using a PCI-5122 scope card, and in many of my aquisitions, I'm setting the sample rate to 40MS/s. Apparently, this is not a valid number and the scope reverts to 50 MS/s
    Later when I try to calculate cycles per second based on cycles per sample, I need the actual sample rate, and 40 MS/s ain't it.
    I'm trying to coerce sampling rate.
    please,.

    The digitizer coerces the sample rate because of how the sample clock is derrived from the Reference Clock.  The following information is on page 13 of the specifications:
    http://digital.ni.com/manuals.nsf/websearch/C6B059C1BDD70101862574C8005567F1
    The sample clock is created by dividing down the Reference clock (internal reference clock is 100MS/s) by decimation, and it divides it by N, which is an integer between 2 and 65530.  
    Thus 50MS/s uses a decimation factor of 2, and 33.3MS/s is the next valid sample rate with a decimation factor of 3.  So when you specify a sample rate that is not possible, the driver automatically coerces the requested sample rate up to the next valid rate.  You can obtain the actual sample rate used in an acquisition using the NI-SCOPE property "Actual Sample Rate", or the LabVIEW VI "niScope Sample Rate.vi".  Using this property, you can get the values you need for your calculations.
    I hope this helps!

  • HT5848 What is the sampling rate and codec for iTunes Radio. Is it lossless encoded?

    What is the sample rate and codec for iTunes Radio? Is it lossless encoded?

    I have to agree with you.  There are several forum discussions on bit rate being as high as 256 kbps but I don't see how it could be more than 96 kbps based on the poor sound quality I'm hearing.  I'm comparing it to an internet radio station that is 128 kbps and sounds much better.
    Am I missing something?

  • If your Lightroom 6 is crashing in the Slideshow module, check the SAMPLE RATE of your music track

    After spending over 2 hours with an Adobe technician who had control over my Windows 7 machine, I've learned something that I don't think Adobe knows yet...  I upgraded from LR 5.7 to LR 6 (not CC) and began having issues when I was working in the Slideshow module.  When trying to add a music track, Lightroom would crash ("unexpectedly quit").  I couldn't for the life of me figure out why.  I turned off the GPU since a fair amount of chatter on the forum related to that, but it didn't change anything.
    So I finally waited patiently for the Adobe Chat line to finally get a tech to respond...and he was exceptionally detailed and methodical in his approach to diagnosing my issues.  I could follow on my screen as he did a variety of things that indicated he understood what he was doing.  Unfortunately he got to a point where he thought (as did I) that he had found the problem/solution...which he thought was related to the bit rate.  He concluded that music with a Variable Bit Rate (VBR) as opposed to a Constant Bit Rate (CBR) was causing the problem.  Also unfortunate was that this "discovery" was near the 2-1/2 hour mark and we did not apply the scientific method to property determine if we had narrowed down to cause/effect.
    Based on my further analysis, he was close, but not right on.  It isn't the BIT rate mode that is causing the crash, but rather the SAMPLE rate.  Turns out that the vast majority of songs in my iTunes library have a sample rate of 44.100 kHz--and those work just fine.  However, I have about 15 songs, mostly downloaded as free background music from the YouTube creation library, that have a sample rate of 48.000 kHz--every single one of those cause my LR6 to crash.
    If you're having a problem with Lightroom crashing in the Slideshow module, check the SAMPLE RATE of your music track.

    If you're on Windows, check out a free program called Audacity--it's fantastic.  With Audacity the process of converting a 48.000 kHz to 44.100 kHz is as simply as opening, changing the sample rate, and then exporting again, as an MP3.

  • Changing the Sampling rate

    Hi,
       May I know how do I change the sampling rate on a Thermocouple node dynamically through a VI on the host ? 
       I notice there is a Config node in the "Start" case where I can set the "Sample Interval Mode" to "Host Driven" but I do not know how to continue after that...
       Thank you very much !
    Regards,
    Xinke

    A user message is created by simply right-clicking on the node and selecting "Create User-Defined Variable."  Once you set it up, that variable will update over the network automatically.
    Once you've got that setup, you need to figure out how you are going to use that variable.  You should probably start here: The LabVIEW Wireless Sensor Network Module - Under the Hood
    Note: User-defined variables are only available in LabVIEW 2011 for WSN.

  • ADjusting the sampling rate on a FIR filter?

    How do I adjust the sampling rate on a digital FIR filter? Thanks in advance.
    -David

    You should really start a new thread instead of posting to one that is 5 years old.
    To answer your question, it depends on your data. I don't use the DFD but with the filter functions in LabVIEW, if you pass a waveform data type to the function, then the waveform data type contains a dt value. So, set the DAQmx Read to return waveform data. If you are using low level filter functions where the input is a 1D DBL array, then the filter has to be configured. With the low level functions in LabVIEW, you use the various coefficients functions that have a sampling frequency input.

  • The sampling rate of FP-AI-110

    How can I change the sampling rate of cFP-AI-110 in Labview 8.5?
    And the filter settings of cFP-AI-110 (50,60 and 500Hz) is equal to the sampling rate?

    Hi!
       I've found this on cFP-AI-110 Operating Instructions, pag. 8:
       "The filter setting determines the rate at which the [c]FP-AI-110
       samples the inputs. The [c]FP-AI-110 resamples all of the channels
       at the same rate. If you set all of the channels to the 50 or 60 Hz
       filter, the [c]FP-AI-110 samples each channel every 1.470 s or
       every 1.230 s, respectively. If you set all of the channels to 500 Hz
       filters, the module samples each channel every 0.173 s. When you
       select different filter settings for different channels, use the
       following formula to determine the sampling rate.
       (number of channels with 50 Hz filter) ×184 ms +
       (number of channels with 60 Hz filter) ×154 ms +
       (number of channels with 500 Hz filter) × 21.6 ms =
       Update Rate"
