More precision in Timestamps

Hello,
I'm acquiring 2.5MS/s with a DAQmx card. That means that my timestamps must have more than ms precision... When I have ms precision I get around (I don't know if it's exactly that) 2500 samples with the same time (for example 2500 samples at 0,023s).
So, how can I get more precision in my timestamps? I read something about getting another counter channel and use it as timestamp, but I want to know if there's any other path for that? I'm already acquiring 8 channels and 'fighting' to save them, I didn't want to add one more channel. And I need timestamps for EACH channel, and not one for all of them...
Thanks for the help,
Rafael

Timestamps have 64 bit for 1 second so the absolute accuracy is much greater, maybe it's just the reprsentation.
Where do you read the timestamp?

Hi
06474 is a MM-PUR error . It will also have effection to MM prochase order process.
Error message 06 474 with item category W and M contracts occurs if the
material on the PO has the same short description (text) as a non-stock
item from the referring contract.
If you change the description of your short text on the PO item (ex.
text1) or you insert a material master with a description the error
message will not appear.
The error message that is generated is part of standard functionality.
It is designed to prevent you from having a duplicate material.

The code listed above is where the error is generated. When there is no
material master (EKPO-EMATN) and the short text on the PO (EKPO-TXZ01)
is the same as the short text on the contract (KEKPO-TXZ01) and the
contract is item category M (PSTYP-MUNB) or W (PSTYP-WAGR) then the
error is generated.
You can set the message to 'W' in SPRO t-code:

I hope this information will help you.

Note 371796 - Msg 06474: Please specify short text more precisely
ME21N, ME22N, ME23N
Message 06474: "Please specify short text more precisely" for a purchase order with reference to a material group contract.
Additional key words
ME21, ME22, material description
Cause and prerequisites
In the new transactions for the purchase order, the system displays the message for a material group contract with reference, which is correct, if there is an assigned material without a material number and the short text, which was copied to the purchase order from the contract to help you, was not changed to the actual material text. In this case, the short text of the material should be more specific in the purchase order than that for the material group in the contract.
For situations in which the specification of the purchase order text does not need to be checked, the message could be made adjustable in Customizing.
In Transaction ME21 and ME22, the text is not copied and must be entered manually. However the system then no longer carries out a check.
Solution
For situations in which the specification of the purchase order text for contracts with the item category material group should not be checked, this note enables you to set error message 06474 in Customizing.
See the advance corrections.

How can i measure the transmision time in gpib with visual basic with more precision if i use time() function?

I want to take a measurement of the time that i use to make a gpib transmision in a Visual Basic program,i use the function TIME() to take the time in the begining and other time in the end,but this way only give me precision of seconds, and i want miliseconds,can i use other function,other way?
Can answer in spanish?

Try using GetTickCount() API function, which provides millisecond precision. If you need more precise timer, try using QueryPerformanceCounter() function.

Controling speed changes with more precision? is it possible in FCPX?

controling speed changes on clips with more precision? is it possible in FCPX? other than the presets?

where is it that you can change the values...I have read that you open the retiming bar in the timeline...didn't see anywhere to change the values..sorry I'm sure it's right in front of me, but?

How to paste audio clips more precisely?????

Im just getting to know my brand new Logic Studio. Im working on a track just to try to get to know my new Logic.
So in trying to paste Audio clips on a certain point, it wont allow me to get it bang on where desired point. Its always
a little off. For example Im trying to copy and paste the first verse to build the 2nd verse. I dragged the bar to the deseired
point which is 20 1 1 1. When I paste in my region or audio clip its like 21 4 4 239. After this I notice I try enlarge the screen
to make it more precise and as I drag it the Audio clip goes past it or before it a little out of time.
Maybe its something to do with the audio clips themselves Im not sure but this never happened to me in Logic Express...
Thanks guys

You know, the funny thing might be to pull them into a single track in FCP and Dona remove gaps.
You could try:
Using the browser in STP to list all the files in order. I'm on the road so I can't test this, but what happens if you select them and drag and drop to a single track in multitrack mode?
And how about: in the browser select the next clip, right click and do spot to playhead? If you've jumped to the end of the file in the track it will butt next next one against it.
So a could things to fool with.

Higher precision of timestamp when wrinting to txt

Hello,
I would like to have a higher precision (--->miliseconds) of the timestamp when saving waveforms to .txt. Labview only prints the date and the time in HH:MMS. As I am acquiring data with a rate of 1k, 1000 data values have the same time description in the .txt-file.
Note: This problem only occurs when writing to .txt, it is no problem to get a higher precision by using the graph or the chart.
Any help or suggestions would be appreciated.

Thanks so far.....
Maybe I was not precise enough. What I am looking for is the opportunity to easily manipulate the format of the timestamp, which comes with my data and then write it to .txt. I already used the "Format Date/Time String"-VI to get the time with the miliseconds part and joined this time information with the data of the waveforms, which I also had to extract from the waveforms before, afterwards, but I thought there would be a more elegant way, because if I can extract the ms-part from the timestamp it must have been in it before, right ? ;-) So why can´t I tell Labview to also display the ms-part, when using the "write waveforms to .txt"-VI? I attached a .txt-file with a short excerpt of data, which should visualise the problem.
Regards

Precision In TIMESTAMP

Hi all;
I know timestamp data types has up to 9 precison after seconds.(Ref: http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements001.htm)

SQL> BUt above query has 6(default for timestamp precision) digits and after 3 digits they become zero.(207000).
What i need is to display timestamp exactly 9 digits:
SQL> SELECT systimestamp FROM dual;
SYSTIMESTAMP
02-FEB-07 02.26.51.207569782 PM +02:00
SQL> Are there any ALTER SESSION command or any others to achieve this situation?
Thanks, Regards...

First insert..select is atomic so it will use one timestamp for all insert statements.
For second insert, if timestamp has 9 digits of precision(now it has 6) it may pass constraint(Am i right?)

Moving Clips More Precisely PrE 9

I am moving clips around and many times want to to insert a clip exactly between two other clips. When I do it however, I seem to chop off a bit of one of the existing clips. Is there an easy way to slide in or insert precisely between two clips? It's a pain to go back and patch together the broken clips. Thank you, Stan

I do not understand why, with Snap ON, PrE will shear off a Frame, or two, but if one Moves the Clip slowly, and with little "force," that does not happen. I have never observed similar behavior in PrPro.
If one is doing much of this Moving, it would be wise to check the full Timeline, in case some Orphans have been created. This ARTICLE goes into more detail on Orphans, and how to handle them.
Good luck,
Hunt

Why is Maps more precise than SDK apps? [iPhone]

I'm using Core Location Manager with best accuracy and get latitude and longitude. When I call Google Maps with the lat/long values I get a marker pretty close to where I really am.
If, however, I use the build in iPhone Maps application I get the PRECISE location, which is some hundred meters from what my own app yields.
I'm running on an iPhone 3G.
Does anybody know:
- Whether Maps uses internal APIs not available via the SDK?
- What is the appropriate way to "enforce" GPS over cell tower location resolving (CLManager)
- Any other hints re this issue
Thanks.

More precise JDBC driver error messages?

Hi,
is there a way to tell the Oracle JDBC driver (9.0.2.3) to provide more detailed error messages in an SQLException message string when a table cannot be found? The usual message "Table or view does not exist" does not provide information on the actual table or view that was missing. I would like the table or view name to be included in the message provided by the SQLException.
(In general I would appreciate more detailed error information in the Oracle JDBC driver exception messages.)
Best regards Uwe

perhaps this might help:
* Get error message of an SQLException with the following form:
* 
* <code>Code=<Vendor-specific error code>:'<error message>':SQLState=<SQLState></code>
* <code>
* Note: SQLState "S1000" is returned for general errors or if driver does not support SQLState.
* @param sqlException SQLException to create error code from.
* @return Specific error message or null if sqlException not available.
public static String toString(SQLException sqlException) {
String result = null;
if (sqlException != null) {
StringBuffer sb = new StringBuffer();
while (sqlException != null) {
sb.append("RDBMS Vendor Code ");
sb.append(sqlException.getErrorCode());
sb.append(": \"");
sb.append(sqlException.getMessage());
sb.append("\" : SQLState=");
sb.append(sqlException.getSQLState());
sqlException = sqlException.getNextException();
result = sb.toString();
}//else: input unavailable
return result;
}//toString()
 * Get string representation of a SQLWarning.
 * @param sqlWarning
 * @return Specific error message or null if sqlWarning not available.
 public static String toString(SQLWarning sqlWarning) {
String result = null;
if (sqlWarning != null) {
StringBuffer sb = new StringBuffer();
while (sqlWarning != null) {
sb.append("errorCode=");
sb.append(sqlWarning.getErrorCode());
sb.append(", SQLState=");
sb.append(sqlWarning.getSQLState());
sb.append(",message=");
sb.append(sqlWarning.getMessage());
sb.append(",cause=");
sb.append(sqlWarning.getCause());
sb.append(";");
sqlWarning = sqlWarning.getNextWarning();
}//next subsequent warning

AUDIO TO SCORE is gone and it was much more precise for drum doubling than the doubling function itself.

AUDIO TO SCORE. I used that all the time for drum doubling for the following reasons:
In Logic 9 i always used audio to score for drum doubling because it had much more control over essential parameters than the drum replacement window. Parameters like: Granulation, Smooth Release and Attack Range made sure that i didn't have any flams, too few notes, too many notes etc etc. AND you could see in the sample editor (below the waveform) immediately the effect of the changes made in those parameters!
Now with these parameters gone and only the drum doubling function left, what was a real pro function has become much more cumbersome to use. You can no longer see in detail what changes in parameters does to the out-coming midi. And the lack of the detailed parameters makes drum doubling drop or miss notes, makes flams with the original drum track etc etc.... In short. The drum doubling function is inadequate for pro results.
So this is my suggestion: Apple probably wont reinstate audio to score as it was (i'd love it if they did, it's essential to me and others who does rock mixes in logic instead of protools). But you can do something that's even better:
In the audio file editor (previously the sample editor) make the old audio to score into an advanced drum doubling/replacement editor. Take the audio to score window and parameters and reinstate them BUT instead of outputting different note values make them output to a desired note of the users choice (e.g C1). Without opening the library. It cluters the window and often people want to use their own drum software than apples samples.
It's the realtime view in the bottom of the audiofile editor that makes a difference. And the missing parameters. Without these things a good outcome is based on luck rather than visual reference.

I was doing drum replacement ( adding ) with Audio-to-score for years, and must say, drum replacement is working for me without any flams and much better and 2x faster. I think it is pro feature, with advanced transient detector. Only problem is velocity,as in Audio-to-score.
If automatic threshold not working on some material, you can do fine transient edits in audio editor with visual realtime feedback, you can change output note and delay globally. Also you can hear ( in compare with Audio-to-score), that's why library is opened and sample replacement -after, not difficult to do.

Any place you have a comment could potentially be re-factored into a private method with a descriptive name. When you see 'blocks' in your code delineated by comments, always consider breaking up the larger method into smaller ones. Blocks within loops are also excellent candidates for a private method.
Consider making all string literals in your class into constants that are static and final. (Don't bother doing this for logging message or System.out.println(), it's overkill).
Consider catching the IOException rather than letting it propogate out of the main() method. You should instead display a meaningul message to the user. Stack traces are not that friendly on the eyes to ordinary users.
