Compare two audio files

hi
i have devloped one web application in Flash Builder 4.
i have recorded the user voice  using fms 3.
Already i have one sample voice for pronunciation.
i want to compare the sample voice and user input voice.
i know it's possible in flex
but i don't know how i do.
pls anybody  give some ideas
thanks in advance
regards
athi

I'm afraid I can't tell you much more than I have just did. I only have a bit of experience in this field with MatLab but thats about it. This is what I was able to find within a few minutes on Google:
DAFT.as - The DSP Audio Toolkit for Flash.  The DATF is a wrapper class that  provides simple interfacing with C/C++ DSP functions via Adobe Alchemy.
ALF.as - The Audio processing Library for Flash.  ALF plays an audio file (MP3 or  wav) using the dynamic audio functionality of Actionscript3 and  provides methods for obtaining audio features and manipulating the audio  output stream on a frame by frame basis.
as3mathlib - The Flex/Actionscript Math Library (as3mathlib) is intended to provide a  rudimentary numerical analysis toolkit for the Actionscript/Flex  programming environment.
My best bet would be DAFT.as. Other than that, I can't tell you anything more. You should really get some knowledge about audio (and signals in general) processing in the internet or some technical or university library. Your problem relates mostly to signal processing tasks (which is mostly mathematics) rather than Flex or Actionscript.
Hope those libraries will be of some use.

  • Compare two audio wave files

    Could some one help me on how to compare two wave file for
    similarities also can i provide a facility to record a audio at run
    time and compare with the one that i already have.

    the criteria is when the wave line is tha same, I think this is the best form to compare the content of a wave. Maybe with a range for the error question in the timeline.

  • How can i compare two excel files with different no. of records.

    Hi
    I am on to a small project that involves us to compare two excel files. i am able to do it but am struck up at a point. When i compare 2 different .csv files with different no. of lines i am only able to compare upto a point till when the number of lines is same in both the files.
    Eg. if source file has 8 lines and target file has 12 lines. The difference is displayed only till 8 lines and the remaining 4 lines in source lines are not shown.
    Can you help me in displaying those extra 4 lines in source file. I am attaching my code snippet below..
    while (((strLine = br.readLine()) != null) && ((strLine1 = br1.readLine())) != null)
                     String delims = "[;,\t,,,|]";
                    String[] tokens = strLine.split(delims);
                    String[] tokens1 = strLine1.split(delims);
                   if (tokens.length > tokens1.length)
                    for (int i = 0; i < tokens.length; i++) {
                        try {
                            if (!tokens.equals(tokens1[i])) {
    System.out.println(tokens[i] + "<----->" + tokens1[i]);

    A CSV file is not an Excel file.
    But apart from that your logic makes no sense.
    If the 2 files are of different sizes the files are different by definition, so further comparison isn't needed, you're done.
    If you want to compare individual records, you need to compare all records from one file with all records from the other, unless the order of records is important in which case your current system might work.
    That system however is overly complicated for comparing CSV files.
    As you assume a single record per line, and if one can assume those records to have identical layout (so no leading or trailing whitespace in or between columns in one file that's not in the other) comparing records is simply a matter of comparing the entire lines.

  • Compare two pdf files using adobe acrobat through command line

    Does anyone know how to compare two pdf files using adobe acrobat through command line. I want to do this via command line because we want to compare hundreds of file every day through some automated windows tasks.
    If command line option is not available in acrobat, then is it feasible to make use of acrobat javascript API to do this task?
    Any kind of help will be greatly.

    Command-line: Not possible.
    JavaScript: Possible, but very limited. Basically the only thing you can do is simulate clicking the Compare Documents button. The rest has to be done manually.
    However, it *might* be possible to automate this process a bit more using a plugin. Ask over at the Acrobat SDK forum for more information...

  • Is it possible to play two audio files simultaneously.

    Hi,
    Is it possible to play two audio files simultaneously.
    I modified the 'SpeakHere' to play two audio files simultaneously, it worked perfectly on simulator but get hanged on iphone.
    To this I implemented NSTimer, which regularly checks for both player instance every second.As soon as any player gets stopped Timer task stops the second one forcefully and again starts both.
    thanks.

    Hi Jay
    Do you have the eLearning Suite? If so, you have Adobe Presenter available to you. If you don't, you should be able to download the Presenter installation file and evaluate it.
    Presenter is an add in for PowerPoint. The neat thing about it is that it provides for a Table of Contents type of functionality as you see is configured in Captivate. But the twist with that is you are able to do something you cannot do in Captivate. You are able to insert videos inside the TOC area!

  • Compare two XML files: Analysis and Design

    Hi, Java/XML/JDOM experts,
    I realised that an open source of Java utility to compare two XML is still missing. So I would like to write one for my JDOM excises.
    I plan to do it in three steps:
    1.Define the problem domain.
    2.Design the classes to be developed.
    3.Coding
    Below is the problem domain. Would you review it and tell me if it is fine?
    Best regards,

    Compare two XML files
    Schema assumption:
    The xml files used for the comparison must have the same schema.
    Definition:
    1. Two elements of simple type are said equal if their name and value are identical.
    2. Two elements of complex type are said comparable if their name, attributes are identical.
    3. Two elements of complex type are said equal if they are comparable and their children elements are identical.

    Hi,
    Thanks for reviewing my idea.
    The xml files used for the comparison must have the
    same schema.Including not having a schema at all? And if they do
    have a schema, must they be valid according to the
    schema?I will only support schema based xml files. To include a schema is a good practice. So I will valid them agaisnt schema (is this possible with JDOM? I am testing ...)
    >
    2. Two elements of complex type are said comparableif
    their name, attributes are identical.
    3. Two elements of complex type are said equal ifthey
    are comparable and their children elements are
    identical.Do you plan to require child elements to appear in the
    same order for the two documents to be equal? (Note
    that XML specifically says that the order of
    attributes is not significant.)No. The order is not significant as I use the attributes as the keys to find comparable element counterpart.
    Here is the sample code already tested. Any comments are welcome!
    The next step is to define the "delta xml schema" that will guide me to store the comparasion results. Do you have any suggestions?
    Regards.
    AG
    public static boolean comparable(Element element1, Element element2)
         boolean returnValue=false;
         if (element1.getName()!=element2.getName()) {
              return returnValue;
    } else {
              returnValue=true;
                        System.out.println ("place 2");
         List attributeList=element1.getAttributes();
         Iterator attributeIterator=attributeList.iterator();
         Attribute workingAttribute=null;
         while (attributeIterator.hasNext()) {
                             if (!workingAttribute.getValue().equals(
                             element2.getAttribute(workingAttribute.getName(), workingAttribute.getNamespace()).getValue()))
                                  returnValue=false;

  • How to compare two fmx files

    Hi,
    Is it possible to compare two fmx files , there are few differences between two fmx files , i wanted to know what are the differences.............Thanks.Bcj

    by converting fmb files into xml or text and then using gvimdiff (or similar) on unix or windows will show you the differences. For fmx files, as pointed earlier - you can only see that if they are different or not. On unix you can use strings command (for fmx files) and pipe it to a text file and then do a diff on the files, but that will not be too helpful either.

  • Comparing two text files in a UNIX using shell programming

    Hi All,
    Sorry for posting a UNIX shell query on Database forums.
    I want to compare two text files using shell programming. The two text files are actually Business Objects output extracted in a text format. The two output files are not in a tabular format and are no way similar in looking. I want to take one file e.g. file1 as an input file and compare each line of file1 with the other file e.g. file2. During comparison I want to extract the differences found in another file and if possible the similar data as well.
