  • Is it possible to edit a sound file based on frequency???

    - by K-RAN
    Just wondering if it's possible to go through a flac, mp3, wav, etc file and edit portions, or the entire file by removing sections based on a specific frequency range? So for example, I have a recording of a friend reciting a poem with a few percussion instruments in the background. Could I write a C program that goes through the entire file and cuts out everything except the vocals (human voice frequency ranges from 85-255 Hz, from what I've been reading)? Thanks in advance for any ideas!

    - by thaold
    Hi, how to replace strings in file, based on values from another file. Example, 2 files - input, output input: 12345 1 output: (1,'a lot of text', 'some other info',0,null, 12345), (2,'a lot of text', 'some other info',0,null, 12345), (3,'a lot of text', 'some other info',0,null, 12345), (4,'a lot of text', 'some other info',0,null, 12345), (5,'a lot of text', 'some other info',0,null, 12345); Needs to be done: read values from file 'input', and replace all '12345' with '1' in file 'output'. Thanks for help in advance

  • Are there any simple, stupid, module based, cross-platform, c++ projects that I can check out of a r

    - by leeand00
    I'm looking for one just to get a general idea of how a standard C++ project should be properly setup. (If that's possible... :-p) Here are my requirements for this project: module-based (has libraries/modules that compile into a main program module) compiles cross-platform I'd like to do this so that I can get a hold on the basics of how a good C++ project is setup, and so that I can test out Premake.

    - by SharePoint Newbie
    I looking for free ASP.NET based content management system (CMS) which has the following features: Blogs (Admin, some super users can have their own blogs) Forums (Admins can create forums. Some moderation features) Admin Dashboard Integration with LinkedIn, Orkut and Facebook (native or through freely available add-ons) Support for moderated user registration (moderated by Admin) Windows Sharepoint services 3.0 is an option. With some tweaking, it supports all the above and there are free third party web parts available. NB: The CMS listed must be free, as in beer.

  • How can I construct this file tree based on what files the user is allowed to view?

    - by robert
    I have an array of files that looks like this: Array ( [0] => Array ( [type] => folder [path] => RootFolder ) [1] => Array ( [type] => file [path] => RootFolder\error.log ) [2] => Array ( [type] => folder [path] => RootFolder\test ) [3] => Array ( [type] => file [path] => RootFolder\test\asd.txt ) [4] => Array ( [type] => folder [path] => RootFolder\test\sd ) [5] => Array ( [type] => file [path] => RootFolder\test\sd\testing.txt ) ) I parse this array and create a tree like view based on the depth of the files ('/' count). It looks like this: RootFolder - error.log - test - asd.txt - sd - testing.txt What I have now is an array of filepaths the user is allowed to view. I need to take this array into account when constructing the above tree. That array looks like this: Array ( [0] => Array ( [filePath] => RootFolder\test\sd ) [1] => Array ( [filePath] => RootFolder\error.log ) ) It would be easy to do a if in_array($path, $allowed) but that won't give me the tree. Just a list of files... Another part I'm stumped on is this requirement: If the user has access to view the folder test, they then have access to all children of that folder. My idea was to simply parse the filepaths. For example, I'd confirm that RootFolder\test\sd was a directory and then create a tree based on the '/' count. Like I was doing earlier. Then, since this is a directory, I'd pull out all files within this directory and show them to the user. However, I'm having trouble converting this to working code... Any ideas?

  • How can I setup a flexible local web development environment I can easily sync with a production, Amazon AWS based environment?

    - by user607057
    I'm running on an OS X environment and would like to create a flexible web development environment locally... including the option to run on an Nginx server for my PHP-based application. At the end of the day (or, development cycle), I'd like to be able to hit a switch and have it all sync over to Amazon AWS hosting (EC2, S3) - instances, databases, files, configurations, and all. Are there any simple ways to do this?

  • Get gprof to profile based on wall-clock time?

    - by jetwolf
    My understanding is that by default gprof takes into account CPU time. Is there a way to get it to profile based on wall-clock time? My program does a lot of disk i/o, so the CPU time it uses only represents a fraction of the actual execution time. I need to know which portions of the disk i/o take up the most time.

  • When using SELECT can you modify the value of a returned field based on other fields?

    - by user570759
    When using MySQL SELECT can you change the value of a returned field based on other fields? For example, if I have this select: SELECT city,state,country FROM table Now if city is empty AND state is empty, I want the value of country to returned empty as well (whether country actually has a value or not). Example table: id | city | state | country ----------------------------- 1 | Here | There | MyCountry 2 | | | YourCountry So with the above table, I want the results for id=1 to return Here,There,MyCountry but the results for id=2 should be empty,empty,empty Thanks

  • Are there java libraries to do a word-based diff?

    - by Mycol
    I have two pieces of text. I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts). I need to do this in Java, so a simple output of the differences (like wdiff) doesn't suite for me: I would like to manipulate objects representing differences.

  • How to select data in JSON based on other JSON data? Javascript

    - by user1699030
    Is it possible to select certain data in a JSON Object using other data in the same JSON Object. Similar to MySQL. For example: myObj = {"elements" : [ { "name" : "Hydrogen", "symbol" : "H" }, { "name" : "Silver", "symbol" : "Ag" }]}; I want to select "Hydrogen" where the symbol is "H". Instead of having to put in something like this: document.getElementByID("TEST").innerHTML = myObj.elements[0].name; Thank you in advance.
