How to determine time value of a .wav file in real time as it plays?

Hi all.
I need to build a vi in which a .wav sound file is represented in a Waveform graph, and at the same time, I want to play that file, and have a vertical cursor line running along the Waveform graph, in order to have a visual representation of where the sound track is, in terms of time.
Making the .wav file to appear graphicaly on a Waveform graph was an easy task to do, but then, I was´nt able to extract the time information of that .wav file, at the same time that this file is being played.
This is a very common situation in music players, video players etc, where some kind of graphical artifact, represents in real time where the track is while it plays.

Hi, this is the first ActiveX control I have played with but its really cool.
I read this first: -
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/iwmpcontrolsinterface.asp
Which covers "The IWMPControls interface provides a way to manipulate the playback of a media item."
Then built the attached sample.
It should now be straight forward to attach the position information shown to a graph control cursor postion.
You will need to set a file of your own choosing in the VI first.
Let us all know if this is what you wanted.

How to extract wav file in specific time?

I can now play and record the wav file using java. However how can I edit the wav file and extract a specifc time period of the wav file? Which library or method should I use?
Thanks

Well, I'm not going to give you your code on a silver platter. You'll need to put some effort in it yourself.
So look at that available() method yourself an see if you can improve on that. Look at the api docs, there is loads of information there, and often it will give you pointers on why things are not working.

How to determine the value of -D__SUNPRO_CC?

Could any body tell me how to determine the value of -D__SUNPRO_CC? Iam now using Sun Studio 9.
Thanks in advance.

The C++ Users Guide describes all the predefined macros set by the compiler.
The __SUNPRO_CC macro is a 3-digit hex number. The first digit is the C++ compiler major version number, which is 5 for all releases from WorkShop 5 in 1998 through the current release, Sun Studio 10. The second digit is the minor version number, increasing by 1 for each release in the major release series. The 3rd digit is a place holder for the very rare (none since 1994) cases when we have a micro version number. It is zero in current releases.
The current compiler release is C++ 5.7, so __SUNPRO_CC is set to 0x570.
You can see the macro setting by running
CC -dryrun -c foo.cc
and look for the -D__SUNPRO_CC =0xNNN on the ccfe command line.

Well if you got the Phone Pggray43 at a Local Corporate store in your Area) you should be able to return it as long as you have all the contents.! Phone, Charger and any other accessories that came with it the Box of Course.. As long as you have not went past the 14 Day return.. the store can go over what you used as in Air Time and Data..
Now if you've went past the 14 Day return you be Liable to pay a E.T.F = Early Termination Fee the fee for this is around $300 so hopefully you have not went past the 14 Day return window the Manager if Available is the one I would talk to tell them your on Social Security and you just can't afford a phone as this I'm sure they'll work with you to get something solved..
Hope ya have Good Luck.! b33

Can anybody tell me if this is correct behavior or am I missing something here ?Calling procedure must terminate before data is actually written to the file.
It is expected & correct behavior.

Detecting PDF-image files in real time

Hi,
I'm planning to build a web application that allows users to upload PDF files. I want to be able to check the PDF files in real-time to ensure they only upload PDF text-searchable files, and not PDF image files. Is there anything from Adobe that has this functionality?
I'll probably to integrating it into a .NET web application.
Thanks.

Hi Leonard - thanks for the reply.
I've read up more about Adobe LiveCycle ES and it seems it might be a bit of an overkill for what I'm trying to do. I just need to have some software to check the PDF document whether it is text-searchable or not. LiveCycle appears to be a full document management and processing suite. Is there any more basic Adobe software that can do this kind of check?
Thanks much.

Why can't read access log file in real-time? (Oracle Weblogic Server 10.3)

We can't read access log file in real-time. If access log is rotation to new file so can read access log file but can't read real-time.
*** Oracle Weblogic Server versions 10 R3

what's your meaning? try this command "tail -f access.log".
Threre is a buffer about 8K for WebLogic to write the access info into the log files, so you can't see the access info untill the buffer is full.

How to determine the value of a Standard Value in a routing operation

Dear Experts,
Kindly guide me on how to detemine the value of my Standard Value in the operation of my routing, or in the phase of my Master Recipe.
I mean what determines the value that I enter for the Standard Values: Machine and Labor in the phase of my Master Recipe?

Hi,
In the Routing / Master Recipe, the standard values are based on the lot size.
For Example, if you have the lot of 100 KG, then in recipe the machine time will be 2 hr and labor time will be 2 hours, it means to make 100 KG we require 2 hrs of machine and 2 hrs of labor.
Normaaly all production manager / supervisor will have the date for the hours. The system will calculate will respect to batch / lot size.
If you have order for 1000 KG, then the system will assign 20 hrs for Machine and 20 hrs for labor.
This will be used for Capacity planning and Costing.
Capacity plan here your requirement is 20 hrs for machine and labor. If you have a reacto which wil run for 24 hrs a day, then the order will be completed in a day.
Costing is concerned, all std. valur key will be assigned with an activity type in work center / Resources and the prices for activity type / cost center will be maintained in KP26.
Based on the cost and hours, the system will allocate cost for the order (it will be planned cost). When you are confirming the order you will enter the actual time for the operation, then that will be your actual cost.
Pl do a sample test scenario in your sand box, and surely you will understand more.
The data for Routing / Recipe will be provided by the production manager of the plant and activity price will be provided by the finance team.
Thanks,
JK

How to zero the values that are greater than 0 at time 0?

Hello, New user,
I would like to know how to zero values that are greater than 0 at time 0. I am totalizing gas flow and understand how not to add the negative numbers but am unsure about the positive numbers at 0 flow. I hope I have explained this good enough.
Thank you,
Lisa

I don't understand why the value which should be 0 is actually greater than 0.
How do you determine that the value should be 0, such as no flow, even if the value is greater than 0?
Ryan Shi
Hello Ryan,
The system itself may have an offset of 0.1 V which in the program is related to flow. I do not wish to add this .1 as flow. I want to beable to reset the values to 0 and then when there is flow, to add the flow. If you purchase a program from some vendors you can zero the channel, that is my goal. I want this to be automatic when a switch is pressed. Such as: for 20 seconds, average channel, and use that value as 0 flow then add flow?? I was told averaging may work??
Thank you again,
Lisa Williamson

How to determine the values for Model Parameters in Forecasting

Hello Gurus,
On basis we will determine the values for the Model Parameter values (Alpha, Beta, Gamma, Sigma).
Thanks,
Siva.

Dear Siva,
the values are dependent from the forecast stratey and forecast model.
The forecast strategy determines the method or the techniques that are used to create the forecast. You set the forecast strategy in the forecast profile.
There are some settings that you must make for certain forecast strategies. The table below shows you which settings these are. You make these settings either in the univariate forecast profile or under the Model and Parameters tabs of the Forecast view on the demand planning desktop.
Model initialization is the process by which the system determines the necessary model parameters for the chosen forecast model. These parameters are in following link:

How to calculate rms voltage, rms current and frequency from real time data?

Hello,
I need to calculate the real time rms voltage, rms current and frequency of the received voltage and current graphs using visa read. Actually am trying to monitor the voltage and current parameters of AC load, in this case, am using a set of 4 light bulbs at the moment. Expected frequency is 50 Hz, and rms voltage close to 240v AC, current about 1A.
Attached is the vi picture of what I have been able to achieve so far, courtesy of labview forums. But I need to finally finish this vi by calculating the Vrms, Irms and frequecy. The front panel shows the voltage (Chart V) and current (Chart I) after scaling. Chart VI represents ADC value 0 ~ 1023 of received data. Aray V & I show the binary bits received up to 10 bits of useful data from ADC. Each sine wave from ADC is sampled at 25 samples for the ADC conversion, and sampling frequency of 1.28kH.
I have tried using the RMS vi, but seems I don't know how to configure it correctly to get desired results. Also when I make changes like switching of one of the bulbs so that their is current change, I need to refresh the SERIAL port first before changes show up on the VI. Any ideas on how to improve on this are highly appreciated.
Otherwise, I would appreciate if somebody helps me MODIFY my VI to read the rms values and frequency from received data. This is the last piece of my project, I do appreciate all the help rendered. Am currently using labview labview 2014, student version!
Gavin.

hello,
note that peak voltage (Vpeak) is (240 * 1.414) = 399 V and peak current about 1.414 if intended rms current is 1A.

How can determine the duration of an audio file

Hi,
i'm making speech recognition project using java. i can capture sound by michrophone and playback it. the type of the sound is .wav.
my question is how to determine the recording duration (for example: determine the duration for 0.25 second) because i must recorded syllable,the assumtion is needed less than 0.5 second to say a word. and then.. can this wav file be changed into... binary or integer ?
thanks for your help

FYI I'm newbie in Java,
Yes, I want to limit the audio file lengths to a certain value. What should I do?
I have read wav file using an AudioInputStream, for audio format I'm using sampleRate = 8000.0F and sampleSizeInBits = 8. My friend said if I used 8 bit for sampleSizeInBit (resolution in amplitude) the binary file should be -128 till 127 in range according to the bit. I try this code and the result is binary file which is zero, positive, and negative.
the code
try{
audioInputStream.read(audioBytes);
for (int i=0; i<audioBytes.length;i++){
System.out.println(audioBytes);
catch(IOException ioe){
System.out.println("Error"+ioe);
I'm not sure that the code is right, but it works. Should I change the audioBytes into integer before? I try this code but it doesn't work.
int a = new int[audioBytes.length];
for (int i=0;i<audioBytes.length;i++){
a[i] = new Byte(audioBytes[i]).intValue();
this binary file has been printed in console (Im using texpad). So, how I can write that to file.txt? I'm using FileoutputStream but it doesn't work correctly. Here is the code
FileOutputStream fos = new FileOutputStream(strFilePath);
{audioInputStream.read(audioBytes);
fos.write(audioBytes);
catch (IOException ioe){
System.out.println("Error"+ioe);
When I open file .txt is read as character like this üüüüüüüüüüüüûüüüûüûûû ||||||| ||||||| ||||||||||||||||||||||||||||| ےےےےےےےےےےےے (like using alt plus number)

WAV files resynch every time iPod is connected despite no changes to files

Folks
I think the title pretty much explains my issue. Every time I plug my iPod Classic into iTunes, the software determines tracks to synch and re-synchs every WAV file I've imported and left checked. It has no problem with all 6,000+ mp3 files (they seem to synch fine), but repeatedly resynching the 200 or so WAV files I've got.
No fancy playlists or odd settings - iPod is pretty much stock and is set up to synch checked tracks only. Tried pretty much everything from uninstalling/reinstalling/repairing iTunes to hard reformatting and restoring the iPod. No change. It's almost as though the iPod is detecting changes to the WAV files on the laptop hard drive (like artwork has changed or something similar) and resynching every single time I reconnect.
Right now - and with only about 200 tracks - it's only taking about three or four minutes, but I'm converting most of my music to WAV format, so if it carries on like this the resynch time is going to increase exponentially . . . so I want to try and stop it now (and only synch updated tracks) before it gets out of hand.
Does this sound familiar to anyone else? Any ideas?
Thanks

That means Time Machine isn't sure that what's on the drive is what it expects.

Because of that, it must do a "deep traversal," comparing everything on the volume to the backups.
How are you disconnecting this drive? If you're not ejecting it first, while a backup is not running, that can corrupt the data on it.
Try a "full reset" of Time Machine, per #A4 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).
Also try repairing it, per #A5 in Troubleshooting.

How to create a c++ shared library (.so) for linux real time (for myRio) with Eclipse to use in LabView?

I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif

How to write list values to a text file?

Hi. Does anyone know how to write values stored in a List to a text file? I have a program that asks the user to enter a name and stores it in a list. The number of names in the list depends on how many times the user wants to enter a name. The problem is that my writeToFile method, which handles writing values to a text file, only writes one name and overwrites any previous names. How could I fix this so that it goes thru the list and writes every value to the file? Any hints would be appreciated!
peace
Chris
import java.util.*;
import java.io.*;
public class StoreNames
String name;
char answer;
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
public void anotherName(List a)throws IOException
System.out.println("Enter another name? (Y or N)");
answer = (char)System.in.read();
System.in.skip(2);
while(answer == 'Y' || answer == 'y')
inputName(a);
System.out.println("Enter another name? (Y or N)");
answer = (char)System.in.read();
System.in.skip(2);
if (answer == 'N' || answer == 'n')
System.out.println("Ok. GoodBye");
writeToFile(a);
//prompts user to input names
public void inputName(List a) throws IOException
System.out.print("Enter a name: ");
name = input.readLine();
a.add(name);
public void writeToFile(List a)throws IOException
PrintWriter output = new PrintWriter(new FileWriter("names.txt"));
output.print(name); //Problem area - handles only one line of input, overwrites previous input
output.close();

System.out is an instance of PrintStream (check the API documents for the System class to see this).
So the easiest way to convert from a "print to screen" class to a "print to file" class is to acquire a PrintStream that prints to a file, and use it exactly the same as you'd have used System.out...
So start with your console code...
        PrintStream out = System.out;
        for(int i = 0; i <10; i++){
            out.println("Number " +i);
        }Then you adapt to file code:
        FileOutputStream fos = new FileOutputStream("temp.txt");
        PrintStream out = new PrintStream(fos);
        for(int i = 0; i <10; i++){
            out.println("Number " +i);
        out.flush();
        out.close();Note that we flush the stream because for reasons of efficiency files aren't necessarily written to disk until you explicitly ask the system to do so (memory is fast, disks are slow, that's why).
Closing the stream releases system resources associated with it.
Actually, that's redundant, because close calls flush automatically, but I left it in for clarity.
Any use ?
