Missing VI - RF Record and Playback Reference Application

Tried to load and run "RF Record and Playback Reference Application" just posted on Developer zone. Have all correct versions of SW. Missing MITEoptimization.llb containing optimizeMITe.vi. Found the win32fileiovis but still missing this one. Reference to "file below" on web site but not there.

Thanks, Andrew. I do have the files, but the strangest thing happened. Although the locations of the web page linked to as well as the file locations appear to be identical, the file that is downloaded is different depending on whether I link to it with Firebird browser or IE. Same behavior whether I double click on the file or right click & save as
File sizes are 383KB (short file) and 628 KB (complete file including MITEOptimization and benchmarking files)
Using Winzip 9.0
Should be OK now though.
Tried again later and both were the same. Is it possible that I linked to different servers which had different files?? Noticed that dir.mnu in the win32filieio directory has different time stamp for the two.

Trying to run the example "rf record and playback reference application"

http://zone.ni.com/devzone/cda/epd/p/id/5894 trying to run this example but a lot of files are not being found. I'm using Labview 8.5 with version 4 of the sound and vibration toolkit. I suspect the problem is the old toolkit version. Can someone confirm? Can't find any info on upgrading to toolkit so I suppose it would mean a new purchase? thanks

Hello Mike,
This example is designed for our RF Hardware platform. You need the RFSG driver, RFSA driver, Spectral Measurements Toolkit, Modulation Toolkit, and the advanced signal processing toolkit for the example to run. You should be able to see this under the software requirements at the bottom of the page. The two drivers should be available for download on our website, but the toolkits must be purchased and they aren't generally available with the dev suite.
I hope this helps,
Paul C

Record and Playback performance goes down at high frequency

Hi,
We're testing record and playback using USRP-2920( LV 2013sp1, NI-USRP 14)
To test it, we downloaded record and playback example code.
Signal source is a function generator outputting 6 MHz bandwidth 8 VSB modulation signal.
USRP Rx parameters are center = variant / gain = 0 / IQ rate = 25MHz and Tx parameters are center = same as Rx center / gain = 0 / IQ rate = 25MHz
The problem is... in low carrier frequency like 70MHz, quality of playback signal is great.
But in high carrier freqency like 2.2GHz, SNR and signal power dropped significantly i.e. they tend to drop as carrier frequency goes high.
And the strange thing is as carrier frequency is increased, a small peak on the center is increased as well.
Please check the attatched file to see the tendancy.
So.. my question is why is this tendancy occures?(we tested another USRP and the result was same as before)
and what should we do to reduce this effect?
Regards,
Youngmin

Hi,
I suggest a couple of things:
NI USRP 2920 is a non-calibrated device. So setting a gain value of 0 at different frequencies could mean a different actual gain. So try increasing the Rx recording gain (on the USRP) in cases where you observe low SNR. Similarly Tx is not calibrated.
Is the signal recording done with cables or over wireless medium ? You can try to eliminate any spurious signals if you use SMA cables while recording.
I think the power at the center of the spectrum is the DC offset. You may refer to the DC Offset/LO leakage section in the best practices section here http://www.ni.com/white-paper/13881/en/
Thanks.

When I record and playback multitrack audio I have dropouts

I purchased a new Macbook Pro 13 to record live audio from my Presonus Studiolive Mixer through firewire. Everything works fine, except that there are audio dropouts in the recording and at different times during playback. I have tried another Firewire cable, re-installed the Presonus software, and done all of the
"optimise for audio" things that are recommended by Presonus and their forum. I bought the Mac specifically for this purpose as it has a good reputation for these types of applications. Recording a 48khz and 24 bit. The CPU is idling so I assume it is some type of comms issue between the two devices.
I am getting no-where, and not sure whether this is something that Apple can assist me with.
Any thoughts?

Hi Andrew.
I have exactly the same thing as you.
I removed everything that was pumping on the computer CPU, installed, uninstalled, changed the safemode on universal control, change firewire cable, nothing works!
I contact Presonus support.
They are totally incompetent. They ask me stupid questions and ask me information that I have already given them ! They do not read what I wrote to them and take time to respond. I think they are aware of the problem but they have not solution.
Many of us have the same concerns on Macbook pro 13.
by cons, I have an iMac 24 of 2007 and everything works fine. I have nodropout recording or reading. The problem is with the compatibility between the Macbook Pro 13 and the Presonus 16.0.2. But what incompatible ?
I also bought the Macbook so I can move easily, and does not fill me touse it, it *****!
I do not know what to do and support Presonus does not help me much ...
I put an announcment in my country, if anyone is interested, I sell it ... I had Motu, I've never had one cares ! Yet there was at least 6 years old with PC !

I can't get my vocals to record and playback!

The sound bars move and I can hear myself on my speakers but my voice doesn't record or playback. I'm micing directly in to my computer. My midi keyboard plays and records and plays back. I have it set to vocals and male R&B, monitor on.

Did you figure this out? I am a first time user. I have a mic, plugged in to my mac and I'm trying to lay vocal tracks...can you help me?

DAQ Record and Playback

I have a PCI-6534 DAQ card in a PC and I am trying to record and then playback some motor encoder signals. I used DAQAssistant to create the code and then I have tried to modularize it a bit. I'm guessing I broke something, but I am not sure what.
My problem is that the playback refuses to work and gives me various errors depending on which "lines" parameter I pass in. The lines parameter I use is the same on the recording functions and the playback.
I started by first trying to record on Dev1/port0/lines0:2. Recording worked fine and it produced the required datafile. When I go to play back the file, I get the message
Partial use of physical lines within a physical port is not supported by this device, given the requested Sample Timing Type.
Consider specifying the entire port and tristating the lines you do not want driven.
Property: SampTimingType
Requested Value: Sample Clock
So then I go back and record on Dev1/port0. Again it records fine, but on playback with the same device, I get...
Requested creation of a separate channel for each line is not possible when a digital port is specified as the physical channel.
Specify a range of digital lines, such as "Dev1/port0/line0:7", as the physical channel.
Physical Channel Name: Dev1/port0
HoKay, so I go back again and record on "Dev1/port0/line0:7". Again it records fine and on playback I get...
When writing, supply data for all channels in the task. Alternatively, modify the task to contain the same number of channels as the data written.
Number of Channels in Task: 8
Number of Channels in Data: 1
I am at a loss as to why I can record so easily, but playbacks are a b***h. Help!
Attached are my VI's that I am using.

I think I figured it out.
When I created the DAQ VIs using DAQAssistant, I did so by selecting individual lines. When I changed things around to get playback to work, I simply changed the text field going into the lines to be "Dev1/port0". I could never get this to work.
I went back and regenerated the playback VIs using DAQAssistant, this time specifying a port output (instead of lines). This time it read and played the data fine.
The moral is that if you use DAQAssistant to generate VIs, be very careful when you change the parameters on those VIs.
Attached is my new test program which works well.

FS7 don't record and playback anymore

Hi there, my FS7 "died" on job. at first in starts flickering, then it completely refuse to record.i tried everything, all reset, new firmware, reinstall firmware, an all-file from a working FS7, EVERYTHING. but nothing helped... after pushing "start record" nothing happens... no message, nothing... if i turn on the camera, it's booting, every seems normal, but if i press a record button, nothing happens... same for the thumbnail button, it don't came up with the recorded footage. only one trick let my camera recording: when i push and hold a record-button and turn the camera ON, it starts recording during booting (at first the tally is blinking, thats it is stable an recording)... when I STOP recording, and press again start -> nothing happens... but turning on the camera with holding down the record button works...
any ideas?
i contact the prime support, they will have a look, but i just want to ask you guys before sending the camera to sony and be 2 ore more weeks without a camera. thx in advancedennis

Maybe a long shot.... but is the "Hold" switch on the side of the camera on? (don't think there's any menu setting about playback... but there is certainly a menu setting to disable the record button(s) using this switch.

External guitar won't monitor on playback. Will record and playback.

When playing into Logic using Orpheus I can hear my guitar. as soon as I start the transport it disappears from monitoring but works, and is heard, in record mode . What's going on! It will playback once recorded.

Hi... thanks for your reply.
I don't really understand the flow through Logic and Orpheus but I'm sure that this has worked correctly with the default settings before... I have tried with "i" on and off and don't really understand what it does but it doesn't seem to make any difference.
I don't know if anything in Logic is corrupted.. Can you somehow throw away the preferences and reset it?
I don't understand the monitoring section of Orpheus and run it in default mode which is DAW and don't use the MIXER settings.
I'll check out low latency mode but ams sure that it is unchecked.
It's a real drag to record an electric guitar ...you get the sound of the guitar with the music stopped which disappears when you go to play mode... comes back when you hit record and play's back once recorded.
WHAT IS WRONG IS THAT FOR SOME REASON THE TRACK'S SIGNAL IS NOT RUNNING THROUGH LOGIC. I'M SURE THAT IT'S SOMETING, LIKE YOU SAY, IN THE SOFTWARE STOPPING THE SIGNAL GOING THROUGH LOGIC'S AUDIO ENGINE??? IT SHOULD WORK WITH SOFTWARE MONITORING TURNED ON???

Recording and playback 'hiccups'

Hi all,
I'm new to Soundbooth and I hope you can help me out.
I'm using Soundbooth on a laptop (Lenovo, Win XP, 3GB of RAM), and I use a Samson C03U mike through a USB port. I record directly to the laptop's hard drive.
Often when I record a longer take (say, more than 10 seconds), I experience a hiccup in the recording, say a tenth of a second of silence, and then recording resumes normally.
The hiccup can also occur during playback, which can become frustrating, as I continuously play back the audio, and keep a close eye on the 'waveform,' to decide if the hiccup is really there (from recording) or just a temporary thing that happens in playback.
Has anyone else experienced this? Any troubleshooting advice. Much appreciated.

EZQuest Pro Audio FW400 Plus Hard Drives are a great choice.
http://ezq.com/productinfo.php?productsid=81
They have a larger buffer than most all other drives. Optimized for pro audio applications (Pro Tools certified). They run cool, very fast, are built into a heavy duty case, and last longer than any other drive I've owned. 2 year warranty.
A little more expensive than the others, but worth it, imo.
Seriously, consider a Pro Audio Plus Firewire drive.
I'm using the Alesis IO|26 right now also. Running tons of audio tracks. Not a hiccup in playback or 8 track live recording.
FYI, to maximize the stability of the entire set-up go in this order: use the Alesis power supply to boot and power your IO|26. Turn on your FW drive - wait for the drive to mount, then connect the IO. Then launch your software.

BB

Audio Skipping in recording and playback

Hey gang,
Ever since my Leopard install a few weeks ago, Soundtrack (2.0.1) has been skipping playback very bad. The audio cuts out for a split second every 2 seconds or so, and it's random and nasty sounding. Clearly this won't do. Ironically, myspace and other websites sites with media are also having the same problem.
anyone have an idea what the deal is?
I haven't changed my hardware config, but upggraded OS's, and everything had been running well under the previous OS. I notice a general sliggishness that I fed with more ram and it's still a problem. Before I start throwing more hardware the problem... your advice please.
ran diagnostics, everything seems to be working mormally,
what's next?

Okay Update for ya,
Took ol' Bessie into the apple store tonight to see a Genius.
Genius Mike at the apple store downtown performed a boot using his own external hard drive (running leopard). We were experiencing the same problem booting with his drive... a metronomic clicking gap popping (every second, like a clock) when listening to flash-based audio in safari. I had uninstalled my pro apps so I wasn't able to test soundtrack pro, but I imagine the same thing would have happened, because the safari audio was screwy.
just to be clear, iTunes is NOT screwed up for me. In fact, iTunes plays perfectly, which is why I'm still skeptical that this is a hardware issue. Mike at the apple store suggested this was a hardware issue that might be solved with the purchase and installation of a new motherboard ($875). I was not so keen to do that right away. I'm going to try a fresh install of OsX 10.4 first, after I back up everything to the 1TB external drive i bought on the same visit.
I want to again make it clear what my problem is...
I don't know which of these is the CAUSE or EFFECT of the problem but here they are:
- a process named coreaudiod (you can find this in activity monitor) is showing a rhythmic increased level of activity every one second, spiking to about 3-5%. Then it pops back down to 1% for a few seconds and jumps back up every second for 3-15 seconds.
- audio in safari (only flash driven audio like youtube and other flash sites) skips/pops or gaps for an instant every second. This repeats 3-15 times and then there is like 3-4 seconds of clear audio, and then the whole thing repeats
- system sounds from skype or aim (incoming message sounds) are also affected, but since they're so breif, usually, they sound like they're cut off half way through the sound.
- the same rhythmic audio popping occurs when playing back or recording in soundtrack pro.
- the following applications are NOT AFFECTED: quicktime, iTunes, logic pro, logic express
I am lividly upset at this problem because of my nearly persistent use of soundtrack pro for the last year... it's totally unusable now.

Recording and playback from microphone on MAC OS X?

Hi there,
I have tried out recording using JavaSound....on Windows it works fine, but not on MAC OS X ... it give an "audio data not supported error".
So then i try using quicktime java... refering to the demo file
SoundRecord.java....i need to modify the codes....and make it into an applet. And since i will be runnning it from a CD, i need it to save on hard disc and later on retrieve it to Playback.
Has anyone dealt which this similar problem?
Please help me, i need to solve this as soon as possible.
Thank you.

As i browsed thru the net...that is all i get...JavaSound cant work on MAC.So now i am doing using QuickTime Java. But i get an error when i run the applet...java.lang.SecurityExecption: Only able to capture media with security settings when class is signed.
What do i do then?
I tried making it signed with a dummy certifiate...it is signed...but when i run it i get the same error message.
Please, i need this to be solved as soon as possible.

Record and playback of OATS functional testing in multiple tabs

New tabs functionality have been a part of browsers for sometime now. But Openscript doesnot record any action relating to new tabs. Is there a way to modify the code so as open new tabs and switch between tabs during the playback?
This will reduce sufficient time during testing of multiple URLs which share the same cookies.
This is required for Fusion Functional testing.

Permissions needed to use the 'Record and playback' feature

What level of permissions is needed to use this feature, on the ES workbench.
Cheers,

i'm not the admin of the server, but one of the users that was created gives the following message when I try and start the feature.
'you must possess the 'Process Recording Read/Delete.' permissiosn in order to....'
I was looking for a reference to the list of permissions in LC. I did not see if in the docs.

Record and Playback troubleshoot

I am new to recording script via SAP GUI but I know there is a way that after you have recorded a script and saved it, you can playback and select the play button and choose a script from a pop history directly under the play button; you dont have to select play and chose a script from an open folder window... anyone know how to enable this feature? I've tried everything...

Hi thanks for your response.
I know that is a way you can initiate the script to run, but what I was referring to is once I've created a script and want to play it, I would select the play button and a pop-up window opens to browse for the script in my folders. I know there is a way that instead of having to search for them, I should be able to click on the play button and a drop-down will come up beneath the play button and I can quickly select a commonly used script instead of having to go out and search for it via the open folder window... does this make sense?

How to record and playback waveform?

Hi,
I would like to record the waveform of my signal and then playback again for analysis purposes.
My current VI can read the signals from 2 channels of my oscilloscope (as shown in the picture) using the waveform chart. How and what should I include in my VI so that I can playback the signal waveform so that I can trace back the place where I previously could not stop the signal in time to obtain the result i want?
Also, is my cross correlation connected properly in the VI? Because while running the signal, this is the waveform I got from the above 2channels waveform (which I think its wrong).
Thanks for much! Your help is greatly appreciated! =)

Acquire Multiple Waveforms(crosscorrelation).vi ‏77 KB

To record (or to save) the acquired data on to disk use the TDMS vi's placed in Files I/O-> TDM streaming..
There will be some example shipped along with the LV on how to use this files.
So once all the data have been stored to the disk read them back (u have to create another vi for reading them) and populate the same to the w/f chart (read small chunks of data = the sampling rate , so that you can exactly play back the data when u were acquiring. This also will not hog your CPU if the data stored is huge)
