Crackle at the end of a loop

There is always a quiet but annoying crackle at the end of my loops when I record from a real instrument.
What can I do?

I haven't noticed a "crackle" but I have noticed that sometimes when I create a loop it ends up with its tail chopped off. And when this happens, these loops have the missing tail added to the front of the loop.
It's really annoying and I haven't found any way to reproduce the problem consistently (otherwise, I'd file a bug).
All of my loops are the spoken voice, so it's easy to tell when the first bit of audio is actually from the last bit of speech from the end of the loops.
This happened on GB '08, both before and after the latest set of patches (circa Sept '07). I'm using a PowerMac G5 dual 2GHz, for what it's worth.

Inserting a pause at the end of a loop in a film clip...

Hi,
I just scanned in 16 frames from old 16 mm film and created a short clip in .swf, by default the clip is looping.
I want it to loop, but all I want to do is place a 5 second pause at the end of the short 1 second clip before it starts up again. How would I do that? Or is there a simple tutorial on this?
I am using CS4 Flash Professional.
Thanks.

OK thanks much,
So to do that, do i begin by highlighting the last frame (the last frame of the movie itself - actual film image) on the timeline, and go to main menu and select Insert>Timeline>Keyframe? Then insert stop(); on the last frame via the actionscript panel?
Then highlight the first frame and insert the setTtimeout() and play() onto the first frame?
I inserted the stop() command on the last frame and the clip now stops...
I tried adding this script on the last frame and clip stops but does not repeat after 5 seconds...
stop()
setTimeout(5)
play();

How do I increment a variable at the end of a loop to run it through the loop again?

I'm new to LabVIEW programming and I'm trying to write a small program that just receives a lower and upper limit, and whether the user wants to increment or decrement the number. I can't figure out how to increment the number after the simple calculations have been done and to run through the loop again with the incremented number. Right now I'm using a while loop inside of a case structure where true decrements and false increments.

Here are a few possibilities.

How do I get a song to stop at the end in garageband on ipad 2?

When a song in Garageband (on ipad 2) reaches the end, it immediately loops back to the beginning and starts playing again. I'd like to use Garageband as an accompaniment to live performance. So, how do I get the song to stop (and not restart) at the end?

I really wish the Apple team would fix this. It's one of those nagging things that was overlooked, I would imagine, and no one but musicians that perform would notice.
Anyway, my workaround is this. I just put a really long silent space at the end of the song giving me time to stop it before it loops.
Hey ipad/garageband team - How about a new release of gargageband?

I tunes player gets stuck at the end of the song

When I play albums from external drive library sometimes a song gets stuck at the end and keeps looping at the last a second or two, and doesnt go to the next song. If I restart iTunes it will play OK. It happened more than a dozen of times.
What is the problem and how to fix that. Its annoying to restart the iTunes all the time.
thanks,

Presnently experiencing this 'last second' glitch downlaoding songs from a CD. The first CD transferred okay. The second CD will not import beyond the last second of any – first, second, middle, last – selected song. FORCE QUIT , eject CD, and reinserting the CD does not change the issue.

Stopping the File Open At the End of Loop

How can I make the script skip the "docRef = open(fileList[i])" at the end of the iteration once all the files are opened? Is there a way to get rid of
this by perhaps getting the total number of files on a folder and assigned it as a variable 'max", such that if the variable "i" is eventually equal to
"max," the the script will not execute the last action on the iteration?
As of now, this loop (taken from Paul Riggott's response to my question before regarding folder processing) is generating the following error:
Error 8000: Cannot open the file because the open options are incorrect
Line: 20
-> docRef=open(fileList[i]);
Here is the script I am working on:
var startDisplayDialogs = app.displayDialogs
app.displayDialogs = DialogModes.NO
// ask the user for the input and output folders
var inputFolder = Folder.selectDialog("Select a folder to process")
var outputFolder = Folder.selectDialog("Select a folder for the output files")
if (inputFolder != null && outputFolder != null) {
// get all the files found in this folder
var fileList = inputFolder.getFiles()
// open each one in turn
for (var i = 0; i < fileList.length; i++) {
// The fileList includes both folders and files so open only files
if (fileList[i] instanceof File && fileList[i].hidden == false) {
// get a reference to the new document
var docRef = open(fileList[i]);

The main problem is
var fileList = inputFolder.getFiles();
You are getting a list of all files and folders that exist in that folder, they could be text files etc.
It is better to specify the file types IE:
var fileList = inputFolder.getFiles(/\.(jpg|tif||psd|)$/i);
As this will only get a list of files that are jpg, tif or psd

Highlighted button Disappearing at the end of loop?

Hey guys,
I have a simple menu with a few buttons and a short clip in a drop zone and a song in the background. All of this takes a minute to reach the end and once it reaches the end it loops but after the loop the highlight is gone and the buttons wont work ( on a DVD player).
Any suggestions will be appreciated.
Cheers,
Alex

MIDI Record automatically loops to the end

GarageBand 10.0.3
I recorded something with the software midi Keyboard (Using the normal Apple Keyboard) and I guess I pressed some wrong key that changes some magic settings.
Anyway, my problem now is that whenever I record something, after finishing it automatically repeats that newly recorded region until the end.
How can I turn this off?
Cheers,
Michi

You may have enabled the Cycle Region. Is there a yellow bar across the Track area?

How can I use "write to spreadsheet" during the data is taking but not the end of all the loops

Hi,
I have to run an experiment on Labview 6 or 5. I don't have Labview 7 on that computer for some reason. My experiment is talking about 1000 hours, and I have a probelm on storing the data. Right now I am using "Write to spread sheet" and I set the "append" to false. And the data is installed at the end of the experiment, that means after 1000 hours. In the mean time if somthing oges wrong like power cut or what, I will lose all the data. So what I want to do is to save the data evertime when the data is took. I tired to set the "append" to true, but it does not let me to choose the "file path"--- when I choose this and select write on new or excisting file, it said" you may not be able to save on a exciting file" and it does not let me create a new file either. If anyone have the lidea like how can I use the "wrtie to spreadsheet" function and at the same time can install the data everytime inside the look, please let me know. Thanks alot.
KL

KL,
It sounds like you want to periodically save your data so it is in smaller files. (great idea) For this operation you will not want to append the data...if something happens to your system while the file is open it could become corrupt and ruin all the data. You need to write the new block of data to a new file every time. Now...this depends on how big your data is...if you only have like 500k of data to write in a block you should probably write several blocks before starting a new file. I don't know enough about how much data you are acquiring. In either case...the write to spreadsheet file.vi will need a different name each time it is called and you will not want to append. Append = false.

How to delete the ends of line ["\n"] in a String before parsing

hi, i'd want to parse a String with Regex/Pattern.
This String contains ends of line i want to delete before applying my parsing treatment.
I've tried to do that by replacing the character "\n" with "" :
    // the original text
    String orgTextToParse = new String(buffer);
    //we create a pattern to recognize the ends of line
    String regExpEol = "\n";
    Pattern patternEol = Pattern.compile(regExpEol);
    Matcher matcherEol = patternEol.matcher(orgTextToParse);
    // the new text without end of line
    StringBuffer newTextToParse = new StringBuffer();
    // we replace the "\n" by ""
    while(matcherEol.find()) {
      String REPLACE = "";
      matcherEol.appendReplacement(newTextToParse,REPLACE);
    matcherEol.appendTail(newTextToParse);
    System.out.println("[new string start] " + (newTextToParse.toString()) + " [end of new string]");Is there an appropriate way to delete "\n" ?
(perhaps a method of the Pattern or Matcher classes... ?)
thanx

The second (optional) argument to Pattern is a set of flags. Take a look at the Javadoc.
The 'genomic' implication is that the EOL is an arbitrary line break for human consumption so it does look like you need to remove the EOL. I would just use replaceAll() since it can be done with one line of code (or just a couple if you pre-compile the regex) without the need for any looping.
line = line.replaceAll("\n","");Edited by: sabre150 on Dec 29, 2007 10:27 AM

How to add spaces at the end of record

Hi Friends,
i am creating a file which contains more than 100 records.
In ABAP i have internal table with on field(135) type c.
some time record have length 120, somtime 130 its vary on each record.
but i would like to add space at the end of each record till 135 length.
Can you please help me how to add speace at the end of record.
regards
Malik

So why did you said that in your first posting? My glass sphere is out for cleaning...
Instead of type c use strings and add spaces until they have the appropriate length.
loop at outtab assigning <pout>.
while strlen( <pout>-val ) < 135.
concatenate <pout>-val `` into <pout>-val.
endwhile.
endloop.

How to add a character at the end of an array element that meets certain criteria.

Hi. I am using CF 9.2.1. I started learning CF yesterday, and I am trying to figure out a way to add a special character (like "?", "!"," & ") to an array row if the first row element (say, element [1][1]) has a specific letter like " t" in the word it is holding. In this case the special character will be added at the end of the last row element (element [1][3]).
Example: The take columns are: "Firstname", "Lastname", "Age". If Firstname contains an "s" or "S" (in any order) then add "!" at the end of the row so that :
Sam, Rubins, 26 !
Nick, Palo, 32
Robert, Williams, 28
Oscar, Ramirez, 23 !
I tried using the ReReplace, Refind and the #findoneof functions. I could probably loop through the array and return a value and store, while storing the value in a separate variable and using an if/Boolean function to compare that value and so on.... But I am sure there's an easier and more efficient way. Thanks in advance.
