A + format is represented by the QAudioFormat class. + + The values supported by the the device for each of these + parameters can be fetched with + supportedByteOrders(), supportedChannels(), supportedCodecs(), + supportedFrequencies(), supportedSampleSizes(), and + supportedSampleTypes().

It is also possible to create QAudioInput with a + specific QAudioDeviceId. When you create the audio input, you + should also send in the QAudioFormat to be used for the recording + (see the QAudioFormat class description for details). + + To record to a file: + + QAudioInput lets you record audio with an audio input device. The + default constructor of this class will use the systems default + audio device, but you can also specify a QAudioDeviceId for a + specific device. You also need to pass in the QAudioFormat in + which you wish to record. + + Starting up the QAudioInput is simply a matter of calling start() + with a QIODevice opened for writing. For instance, to record to a + file, you can: + + \code + { + QFile outputFile; + outputFile.setFileName("/tmp/test.raw"); + outputFile.open( QIODevice::WriteOnly | QIODevice::Truncate ); + + QAudioFormat format; + // set up the format you want, eg. + format.setFrequency(8000); + format.setChannels(1); + format.setSampleSize(8); + format.setCodec("audio/pcm"); + format.setByteOrder(QAudioFormat::LittleEndian); + format.setSampleType(QAudioFormat::UnSignedInt); + + QAudioInput *audio = new QAudioInput(format, this); + QTimer::singleShot(3000, this, SLOT(stopRecording())); + audio->start(outputFile); + // Records audio for 3000ms + } + \endcode + + This will start recording if the format specified is supported by + the input device (you can check this with + QAudioDeviceInfo::isFormatSupported(). In case there are any + snags, use the error() function to check what went wrong. We stop + recording in the \c stopRecording() slot. + + \code + void stopRecording() + { + audio->stop(); + outputFile->close(); + } + \endcode + + At any point in time, QAudioInput will be in one of four states: + active, suspended, stopped, or idle. These states are specified by + the QAudio::State enum. You can request a state change directly through + suspend(), resume(), stop(), reset(), and start(). The current + state is reported by state(). QAudioOutput will also signal you + when the state changes (stateChanged()). + + QAudioInput provides several ways of measuring the time that has + passed since the start() of the recording. The \c totalTime() + function returns the length of the stream in microseconds written, + i.e., it leaves out the times the audio input was suspended or idle. + The clock() function returns the time elapsed since start() was called regardless of + which states the QAudioInput has been in. + + If an error should occur, you can fetch its reason with error(). + The possible error reasons are described by the QAudio::Error enum. + + \sa QAudioOutput, QAudioDeviceInfo +*/ + +/*! + Construct a new audio input and attach it to \a parent. + The default audio input device is used with the output + \a format parameters. +*/ + +QAudioInput::QAudioInput(const QAudioFormat &format, QObject *parent): + QObject(parent) +{ + d = QAudioDeviceFactory::createDefaultInputDevice(format); + connect(d, SIGNAL(notify()), SIGNAL(notify())); + connect(d, SIGNAL(stateChanged(QAudio::State)), SIGNAL(stateChanged(QAudio::State))); +} + +/*! + Construct a new audio input and attach it to \a parent. + The \a id of the audio input device is used with the input + \a format parameters. +*/ + +QAudioInput::QAudioInput(const QAudioDeviceId &id, const QAudioFormat &format, QObject *parent): + QObject(parent) +{ + d = QAudioDeviceFactory::createInputDevice(id, format); + connect(d, SIGNAL(notify()), SIGNAL(notify())); + connect(d, SIGNAL(stateChanged(QAudio::State)), SIGNAL(stateChanged(QAudio::State))); +} + +/*! + Destroy this audio input. +*/ + +QAudioInput::~QAudioInput() +{ + delete d; +} + +/*! + Uses the \a device as the QIODevice to transfer data. + If \a device is null then the class creates an internal QIODevice. + Returns a pointer to the QIODevice being used to handle the data + transfer.

It is also possible to create QAudioOutput with a + specific QAudioDeviceId. When you create the audio output, you + should also send in the QAudioFormat to be used for the playback + (see the QAudioFormat class description for details). + + To play a file: + + Starting to play an audio stream is simply a matter of calling + start() with a QIODevice. QAudioOutput will then fetch the data it + needs from the io device. So playing back an audio file is as + simple as: + + \code + QFile inputFile; + inputFile.setFileName("/tmp/test.raw"); + inputFile.open(QIODevice::ReadOnly); + + QAudioFormat format; + // Set up the format, eg. + format.setFrequency(8000); + format.setChannels(1); + format.setSampleSize(8); + format.setCodec("audio/pcm"); + format.setByteOrder(QAudioFormat::LittleEndian); + format.setSampleType(QAudioFormat::UnSignedInt); + + QAudioOutput *audio = new QAudioOutput(format, this); + connect(audio,SIGNAL(stateChanged(QAudio::State)),SLOT(finishedPlaying(QAudio::State))); + audio->start(inputFile); + + \endcode + + The file will start playing assuming that the audio system and + output device support it. If you run out of luck, check what's + up with the error() function. + + After the file has finished playing, we need to stop the device: + + \code + void finishedPlaying(QAudio::State state) + { + if(state == QAudio::IdleState) { + audio->stop(); + inputFile.close(); + } + } + \endcode + + At any given time, the QAudioOutput will be in one of four states: + active, suspended, stopped, or idle. These states are described + by the QAudio::State enum. + State changes are reported through the stateChanged() signal. You + can use this signal to, for instance, update the GUI of the + application; the mundane example here being changing the state of + a \c { play/pause } button. You request a state change directly + with suspend(), stop(), reset(), resume(), and start(). + + While the stream is playing, you can set a notify interval in + milliseconds with setNotifyInterval(). This interval specifies the + time between two emissions of the notify() signal. This is + relative to the position in the stream, i.e., if the QAudioOutput + is in the SuspendedState or the IdleState, the notify() signal is + not emitted. A typical use-case would be to update a + \l{QSlider}{slider} that allows seeking in the stream. + If you want the time since playback started regardless of which + states the audio output has been in, clock() is the function for you. + + If an error occurs, you can fetch the \l{QAudio::Error}{error + type} with the error() function. Please see the QAudio::Error enum + for a description of the possible errors that are reported. + + If an error is encountered state changes to QAudio::StopState. + + \sa QAudioInput, QAudioDeviceInfo +*/ + +/*! + Construct a new audio output and attach it to \a parent. + The default audio output device is used with the output + \a format parameters. +*/ + +QAudioOutput::QAudioOutput(const QAudioFormat &format, QObject *parent): + QObject(parent) +{ + d = QAudioDeviceFactory::createDefaultOutputDevice(format); + connect(d, SIGNAL(notify()), SIGNAL(notify())); + connect(d, SIGNAL(stateChanged(QAudio::State)), SIGNAL(stateChanged(QAudio::State))); +} + +/*! + Construct a new audio output and attach it to \a parent. + The \a id of the audio output device is used with the output + \a format parameters. +*/ + +QAudioOutput::QAudioOutput(const QAudioDeviceId &id, const QAudioFormat &format, QObject *parent): + QObject(parent) +{ + d = QAudioDeviceFactory::createOutputDevice(id, format); + connect(d, SIGNAL(notify()), SIGNAL(notify())); + connect(d, SIGNAL(stateChanged(QAudio::State)), SIGNAL(stateChanged(QAudio::State))); +} + +/*! + Destroys this audio output. +*/ + +QAudioOutput::~QAudioOutput() +{ + delete d; +} + +/*! + Returns the QAudioFormat being used. + +*/ + +QAudioFormat QAudioOutput::format() const +{ + return d->format(); +} + +/*! + Uses the \a device as the QIODevice to transfer data. + If \a device is null then the class creates an internal QIODevice. + Returns a pointer to the QIODevice being used to handle the data + transfer.
