Detailed Description

The KAudio class is a very easy means to playback digital audio data. A standard procedure looks like this example:

// Class definition class DemoClient : public KTMainWindow { Q_OBJECT

public: DemoClient(); KAudio KAServer;

public slots: void playOK(); // [...] }

// Program // ************* Initialization ****************************** DemoClient *myClient = new DemoClient(); if (myClient->KAServer.serverStatus()) { cerr << "Failed contacting audio server\n"; exit (1); }

// ************* If you want to recieve Qt signals *********** KAServer.setSignals(true); QObject::connect(&KAServer, SIGNAL(playFinished()), this, SLOT(playOK()));

// ************* Playback ************************************ KAServer.play("/my/sounds/is/here.wav");

See democlient.cpp in the kdebase sources for a full program showing more possibilities of the KAudio class

 KAudio ()

Create an Audio player

KAudio ()

Destroy the Audio player again

bool  play ()

Play the Wav last set via setFilename(filename) or play(filename)

bool  play (const char *filename)

Set filename as current media name and play it

bool  play (QString& filename)

Set filename as current media name and play it

bool  setFilename (const char *filename)

Set the "current" Filename. This file can be played later with ::play()

bool  setFilename (QString& filename)

Set the "current" Filename. This file can be played later with ::play()

void  setAutosync (bool autosync)

If true is given, every play call is synced directly.

void  setSignals (bool sigs=true)

If you want to recieve a Qt signal when your media is finished, you must call setSignals(true) before you play your media.

bool  stop ()

Stop current media

void  sync ()

Sync media. This effectively blocks the calling process until the media is played fully

int  serverStatus ()

Query Server status. 0 means OK. You MUST check server status after creating a KAudio object.

void  playFinished ()

[signal]

Signal gets emitted after current media has been finished. This signal only gets emitted, if setSignals(true) was called before. Do not forget to include this signal in your own derived class if you want signals.
