audio - Sound Analysis/Editing in Android -

August 15, 2011

I should know how difficult it is to analyze and edit sound in Android. My project will be a type of DJ application.

I think audiotrak is the most suitable library, right? Some Android DJ apps display the spectrum of sound, apply effects, change speed, mix the act ... do they use a more powerful external sound library?

For the issue of performance, is Java very fast (or is there a risk of delay)?

And one last question: how Korg put his pad in the iPad, the wormx is being ported to Android, AngryBird now works on iPhones and Android, ect ... all these The application is being ports without being rewritten on any platform ... How do they do it? That's because they are written in the "original code"? Should I consider this option so that I can use other sound libraries?

Thank you.

To edit the sound or apply sound effects in a stream, you can use the AudioTrack < To configure with one of the / code> packages, the audiofile fect package has the option of android.media.audiofx , such as equalizer etc ... . To analyze sound, you should most often apply FFT algorithms to client AudioRecord or some re-received bytes .

IronPython in C#: No module named xmlrpclib -



    I am trying to create a web application with an interactive console for IronPython. When I try to import xmlrpclib into the General console of IronPython, it works. However, if I use IronPython inside my C # code, then it does not put an exception "a module named xmlrpclib", is it a known issue? Any solution to solve this issue?   Here is the code:    var testcode = @ "import xmlrpclib; apiarver = xmlrpclib.ServerProxy ('address', allow_none = true); print APIServer.Hello () ; "; Mystream str = newest Mystream (); ScriptEngine Engine = Python. Cretegenine (); Engine. Retyme.io asset output (str, system text encoding. ASCII); Engine. Serial.io.setuperoutput (str, systemtext.edcoding.aspx); ScriptScope scope = engine.CreateScope (); ScriptSource src = engine.CreateScriptSourceFromString (testCode); Src.Execute (scope); Sorry for the silly question, it has come to know that there is a path used by IronPathon inside me.       The C # code was not correct. I ...






qt creator - QtCreator importing makefile projects -



    Have you ever tried importing Classic C ++ / project into Qt Creator?   Say that I wanted to use some libraries in my GUI project, which must be created. how can I do this?      In Qt Creator 2.0.1 you can import projects using only * * Cmake, * .creator, * .pro or * .qmlproject   Then switch to cmake and you can import the project into Qt builder (Welcome tab -> Open project ...).
