Twisted Documentation: Asynchronous Programming with Twisted - 0 views

  • This document is a introduction to the asynchronous programming model, and to Twisted's Deferred abstraction, which symbolises a 'promised' result and which can pass an eventual result to handler functions.

What's Cooking in PulseAudio's glitch-free Branch - 0 views

  • The first basic idea of the glitch-free playback model (a better, less marketingy name is probably timer-based audio scheduling which is the term I internally use in the PA codebase) is to no longer depend on sound card interrupts to schedule audio but use system timers instead. System timers are far more flexible then the fragment-based sound card timers. They can be reconfigured at any time, and have a granularity that is independant from any buffer metrics of the sound card. The second basic idea is to use playback buffers that are as large as possible, up to a limit of 2s or 5s. The third basic idea is to allow rewriting of the hardware buffer at any time. This allows instant reaction on user-input (i.e. pause/seek requests in your music player, or instant event sounds) although the huge latency imposed by the hardware playback buffer would suggest otherwise.

pyssi - PYthon Signal Slot Implementation - 0 views

  •  
    PySSI is a simple signal-slot mechanism used to implement an observer design pattern as its name implies: PYthon Signal Slot Implementation.Heavily inspired by the signals/slots construct in the Qt framework and iin other similar frameworks, it correlates a base callable to a signal. This base callable's return value is then 'published' to all 'subscribers' i.e. all callables that are connected to the base callable's 'slots'.

OcempGUI Manual - 0 views

  •  
    The event management system of OcempGUI uses a simple approach using signal slots. This means, that objects will register themselves only for specific event types, of which they want to be notified. Any other event will not be sent to them.This reduces the overhead of events the objects have to deal with (either by dropping or processing them) and improves the performance and scalability of the event management system (especially with many objects).

www.apifinder.com - Get Started with API Programming Using Flickr with Flash, C#, or Java - 0 views

  • XML-RPC XML-RPC is the second request format supported by Flickr. XML-RPC uses HTTP as the transport and XML for encoding. In XML-RPC, the method parameters are wrapped in a XML document and POST-ed to the XML-RPC endpoint, in this case http://api.flickr.com/services/xmlrpc/. A XML-RPC request will have this format: <methodCall> <methodName>flickr.test.echo</methodName> <params> <param> <value> <struct> <member> <name>api_key</name> <value><string>..your API key..</string></value> </member> </struct> </value> </param> </params> </methodCall> If the method takes more than one parameter, you will have to repeat the <member> structure for each parameter; you can find detailed instructions regarding the packaging of complex datatypes at www.xmlrpc.com. Here is how to implement this call in Actionscript: var request:XML; var response:XML; request=new XML(); response = new XML(); response.onLoad=function(success:Boolean){ trace(success); trace(this.toString()); } request.xmlDecl = '<?xml version="1.0"?>'; request.parseXML("<methodCall><methodName>flickr.test.echo</methodName><params> <param><value><struct><member><name>api_key</name><value>..your API key..</value></member></struct></value></param></params></methodCall>"); request.sendAndLoad("http://api.flickr.com/services/xmlrpc/", response); Since this is a HTTP POST operation, I have to use the sendAndLoad method of the XML object. Developer Matt Shaw is behind an open source project that provides a XML-RPC library for Actionscript; an introduction can be found at http://xmlrpcflash.mattism.com/, or you can download the library (more details can be found here). Using this library, the call to the echo function shown above would look like this: import com.mattism.http.xmlrpc.Connection; import com.mattism.http.xmlrpc.ConnectionImpl; onLoadListing = function( response:Array ){ trace("Found the following objects:"); var i:Number; for (i=0; i<response.length; i++){ trace(i+". "+url+response[i]); } }; var url:String = "http://api.flickr.com/services/xmlrpc/"; var c:Connection = new ConnectionImpl(); c.setUrl(url); c.onLoad = onLoadListing; c.addParam( { api_key:'...your API key...' }, "struct"); c.call("flickr.test.echo");

Raw Material Software - Juce - 0 views

  • Audio driver classes provide an abstract audio device layer, which transparently supports ASIO, DirectSound, CoreAudio and ALSA devices.

      hmm..ALSA ASIO :))
  • Midi Midi input/output support on Mac and PC Midi message wrapper classes make it easy to manipulate midi using a high-level programming interface Midi buffer classes for efficient collating and editing of midi streams Midi keyboard state objects will monitor a midi stream and provide information about the state of a virtual keyboard Classes for merging and re-timing midi input streams to synchronise with audio streams. Support for reading/writing standard midi format files.

      MIDI .. gotovo sve sto treba .. ovo treba istestirat sto prije.. ..nema input/output na Linuxu .. ali zato bismo mogli korisiti nesto drugo .. glavno da su klase za manipulaciju MIDI podacima dobre.. Kako to da podrzava ALSU ali ne i MIDI hardwer?
    • marcell mars
       
      alsa je framework i za sound i za midi.. da bi podrzavao i jedno i drugo treba to raspisati... nadam se da su dobro odradili midi podrsku jer sam proveo par dana pokusavajuci prokljuviti pyseq tako da ne bi sad ulazio u nesto predugo a da recimo nema istu funkcionalnost... aj probaj vidjeti kakva je podrska za midi na linuxu pa da vidimo sto cemo.. takodjer da li je sve to expozano u python... pyseq je redom popisivao sto je alsa namijenila midiju... eto.. iako bi rado da mozemo uzeti taj framework jer onda mozemo ici u bilo kojem smjeru sa topotom.. ne samo kao midi kontroler...

MidiWeb.org -> home - 0 views

  • The MidiWeb consists of a server/client framework using TCP/IP to connect, receive and send midi data. It allows users to connect unlimited midi devices either locally and/or over the internet and send realtime data to each other. Since MidiWeb uses a simple protocol and MidiWeb client applications are not limited to hardware midi devices. Any language that supports socket connections can be used to develop applications for it including Macromedia Flash. The MidiWeb project is released using the GNU GPL license. Also the MidiWebServer and MidiWebClient are written in Python and will run on most platforms. (e.g. Windows, Mac, Unix)
