  • Sound Effects/Manipulation?

    - by Adam
    Hello, I am creating an android app that basically records an applies an "Effect" on the audio track then plays it back. I got my app to record an play back but I am stuck an not sure where do go from here. I have been Googling for days now trying to find a open source audio library or some way to change the audio after I record it. I currently have it setup to play back using SoundPool an I't lets me speed up an slow down the audio. I would like to do things like change pitch an add echo etc. I will appreciate any responses because I am totally stumped right now. Thanks Adam

  • How Do I Programmatically Set a File Tag

    - by Greg Bishop
    When using Windows Explorer to view files, I'm given the option to set a "tag", "category", or other attributes. For a JPEG a different set of attributes (including "tag") are options. I'd like to be able to set these programmatically. How do I programmatically set a file tag and other file attributes using Delphi (I have Delphi 2010 Pro)?

  • Powerbuilder Dynamic Array Manipulation

    - by TomatoSandwich
    string array[] long lBound, uBound lBound = LowerBound(array[]) // = 1, empty array value uBound = UpperBound(array[]) // = 0, empty array value array[1] = 'Item 1' array[2] = 'Item 2' array[3] = 'Item 3' lBound = LowerBound(array[]) // = 1 uBound = UpperBound(array[]) // = 3 array[3] = '' //removing item 3 lBound = LowerBound(array[]) // = 1, still uBound = UpperBound(array[]) // = 3, still (but array[3] is nulled? I think the line 'array[3]' is wrong, but I think I've read that this should remove the array cell. What would be the right way to remove an array cell? Does it depend on object type? (String vs Number vs Object) Or Can one manipulate the UpperBound value to make it work? i.e. after removing Item 3, I want the UpperBound, or arraylength, to be 2, since this is logically correct.

  • Graphviz or Dynagraph for Graph-manipulation Program?

    - by noahlavine
    I'm looking into writing a program that will show a graph to the user. The graph will change over time (the user should be able to right-click on a graph item and ask for more detail, which will pop out new bits of the graph), and the user might be able to drag parts of the graph around. I would ideally also like to be able to specify the relative layout of certain parts of the graph myself while leaving the overall layout up to a library, but that's not essential. I'm trying to decide on a graph layout library to use. As far as I can tell, the two leading candidates are Graphviz and Dynagraph. The Dynagraph website suggests that Graphviz is for drawing static graphs, and that Dynagraph was forked from Graphviz and contains algorithms for graphs that will be updated. It has a sample program called Dynasty that does exactly what I want. However, the Graphviz site contains an example program called Lefty which seems to do exactly what I want. Graphviz also seems to be much more widely used, judging by Google (and SO) results. Finally, I'd like to code the GUI part in a language like Python or Scheme, which makes me a bit hesitant to use C++ because I understand it's harder to interface that to interpreters. So my question is, which library is better for what I'm trying to do? Do they both have strong and weak points? Has one of them actually ceased development and is just leaving its website up to confuse me? (I've seen http://stackoverflow.com/questions/464000/simple-dynamic-graph-display-for-c and http://stackoverflow.com/questions/2376987/open-source-libraries-to-design-directed-graphs, but I can't tell whether they're right about the Graphviz or Dynagraph choice because of Lefty and also the language issue.)

  • Ruby Programming Techniques: simple yet not so simple object manipulation

    - by Shyam
    Hi, I want to create an object, let's say a Pie. class Pie def initialize(name, flavor) @name = name @flavor = flavor end end But a Pie can be divided in 8 pieces, a half or just a whole Pie. For the sake of argument, I would like to know how I could give each Pie object a price per 1/8, 1/4 or per whole. I could do this by doing: class Pie def initialize(name, flavor, price_all, price_half, price_piece) @name = name @flavor = flavor @price_all = price_all @price_half = price_half @price_piece = price_piece end end But now, if I would create fifteen Pie objects, and I would take out randomly some pieces somewhere by using a method such as getPieceOfPie(pie_name) How would I be able to generate the value of all the available pies that are whole and the remaining pieces? Eventually using a method such as: myCurrentInventoryHas(pie_name) # output: 2 whole strawberry pies and 7 pieces. I know, I am a Ruby nuby. Thank you for your answers, comments and help!

  • Reading Binary file in C

    - by darkie15
    Hi All, I am having following issue with reading binary file in C. I have read the first 8 bytes of a binary file. Now I need to start reading from the 9th byte. Following is the code: fseek(inputFile, 2*sizeof(int), SEEK_SET); However, when I print the contents of the array where I store the retrieved values, it still shows me the first 8 bytes which is not what I need. Can anyone please help me out with this? Regards, darkie

  • Get PocketC File Handle Int?

    - by Nathan Campos
    I'm now taking a look at the PocketC powerful tool, but there is an fileopen function, that generates a integer called filehandle, that is used for most of the File I/O operations of PocketC, than I want to know how to discover the int filehandle from the function? Here is my example function that I'm using at my program: fileopen("\test.txt", 0, 0x00000000); Description of int filehandle: Integer used for file operations, used as a pointer to the fileopen instruction.

  • bit manipulation in java

    - by sarav
    I have a fragment of bytes in a byte[]. The total size of the array is 4 and I want to convert this into a positive long number. For example if the byte array is having four bytes 101, 110, 10, 1 then i want to get the long number represented by binary sequence 00000000 00000000 00000000 00000000 00000101 00000110 00000010 00000001 which equals 84279809 What is the efficient way to do that in Java?

  • gvim Cannot make changes, 'modifiable' is off issues with file explorer.

    - by nos
    In gvim using netrw(the file explorer), I usually middle click a file to open it in the last active window. This just leads to an error stating "Cannot make changes, 'modifiable' is off". Another middle click, and the file opens fine where I expect it to. All buffers are saved, there's no uncommuted changes anywhere. What causes this, and what can I do about it ? Here's a pic when I middle click a file:

  • Parsing a file with hierarchical structure in Python

    - by Kevin Stargel
    I'm trying to parse the output from a tool into a data structure but I'm having some difficulty getting things right. The file looks like this: Fruits Apple Auxiliary Core Extras Banana Something Coconut Vegetables Eggplant Rutabaga You can see that top-level items are indented by one space, and items beneath that are indented by two spaces for each level. The items are also in alphabetical order. How do I turn the file into a Python list that's something like ["Fruits", "Fruits/Apple", "Fruits/Banana", ..., "Vegetables", "Vegetables/Eggplant", "Vegetables/Rutabaga"]?

  • Uploading file from file object with PyCurl

    - by Tom
    I'm attempting to upload a file like this: import pycurl c = pycurl.Curl() values = [ ("name", "tom"), ("image", (pycurl.FORM_FILE, "tom.png")) ] c.setopt(c.URL, "http://upload.com/submit") c.setopt(c.HTTPPOST, values) c.perform() c.close() This works fine. However, this only works if the file is local. If I was to fetch the image such that: import urllib2 resp = urllib2.urlopen("http://upload.com/people/tom.png") How would I pass resp.fp as a file object instead of writing it to a file and passing the filename? Is this possible?

  • Doing 64 bit manipulation using 32 bit data in Fixed point arithmetic using C.

    - by Viks
    Hi, I am stuck with a problem. I am working on a hardware which only does support 32 bit operations. sizeof(int64_t) is 4. Sizeof(int) is 4. and I am porting an application which assumes size of int64_t to be 8 bytes. The problem is it has this macro BIG_MULL(a,b) ( (int64_t)(a) * (int64_t)(b) 23) The result is always a 32 bit integer but since my system doesn't support 64 bit operation, it always return me the LSB of the operation, rounding of all the results making my system crash. Can someone help me out? Regards, Vikas Gupta

  • SSIS DTS Package flat file error - "The file name specified in the connection was not valid"

    - by MisterZimbu
    I have a pretty basic SSIS package that is attempting to read a file hosted on a share, and import its contents to a database table. The package runs fine when I run it manually within SSIS. However, when I set up a SQL Agent job and attempt to execute it, I get the following error: Executed as user: DOMAIN\UserName. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 64-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved. Started: 10:14:17 AM Error: 2010-05-03 10:14:17.75 Code: 0xC001401E Source: DataImport Connection manager "Data File Local" Description: The file name "\10.1.1.159\llpf\datafile.dat" specified in the connection was not valid. End Error Error: 2010-05-03 10:14:17.75 Code: 0xC001401D Source: DataAnimalImport Description: Connection "Data File Local" failed validation. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 10:14:17 AM Finished: 10:14:17 AM Elapsed: 0.594 seconds. The package execution failed. The step failed. This leads me to believe it's a permissions issue, but every attempt I've made to fix it has failed. What I've tried so far: Run as the SQL Agent account (DOMAIN\SqlAgent) - yields same error. DOMAIN\SqlAgent has "Full Control" permissions on both the share and the uploaded file. Set up a proxy account with a different account's credentials (DOMAIN\Account) - yields same error. Like above, "Full Control" permissions were given over the share to that account. Gave "Everyone" full control permissions over the share (temporarily!). Yielded same error. Manually copied the file to a local path and tested with the SQL Agent account. Worked properly. Added an ActiveX script task that would first copy the remotely hosted file to a local path, and then have the DTS package reference the local file. Gave a completely nondescriptive (even by SSIS standards) error when trying to run the script. Set up a proxy account, using my own personal account's credentials - worked correctly. However, this is not an acceptable solution as there are password policies in place on my account, as well as being a bad practice to set things up this way in general. Any ideas? I'm still convinced it's a permissions issue. However, what I've read from various searches more or less says giving the executing account permissions on the share should work. However, this is not the case here (unless I'm missing something obscure when I'm setting up permissions on the share).

  • Python string manipulation

    - by paradox
    I'm trying to split a string into a int list for further processing. But somehow I can't remove certain whitespaces in between elements of the list. The string x is supposed to have a length of 1000 instead of 1019. I tried reading the documentation for python and saw the function strip() for stripping whitespaces from strings. However, it only works for trailing and leading whitespaces. How should I go about removing these whitespaces and also how do I convert a str list to a int list? My code is as follows : import array x = """73167176531330624919225119674426574742355349194934 96983520312774506326239578318016984801869478851843 85861560789112949495459501737958331952853208805511 12540698747158523863050715693290963295227443043557 66896648950445244523161731856403098711121722383113 62229893423380308135336276614282806444486645238749 30358907296290491560440772390713810515859307960866 70172427121883998797908792274921901699720888093776 65727333001053367881220235421809751254540594752243 52584907711670556013604839586446706324415722155397 53697817977846174064955149290862569321978468622482 83972241375657056057490261407972968652414535100474 82166370484403199890008895243450658541227588666881 16427171479924442928230863465674813919123162824586 17866458359124566529476545682848912883142607690042 24219022671055626321111109370544217506941658960408 07198403850962455444362981230987879927244284909188 84580156166097919133875499200524063689912560717606 05886116467109405077541002256983155200055935729725 71636269561882670428252483600823257530420752963450""" y=[] for i in range(0,len(x)): #String is now in a string list if x[i]!='': y.append(x[i]) print(y[i]) print(len(x))
