Detailed Description¶
QAudioRecorder *recorder = new QAudioRecorder(); QAudioProbe *probe = new QAudioProbe; // ... configure the audio recorder (skipped) connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)), this, SLOT(processBuffer(QAudioBuffer))); probe->setSource(recorder); // Returns true, hopefully. recorder->record(); // Now we can do things like calculating levels or performing an FFTSee also
- class PySide2.QtMultimedia.QAudioProbe([parent=None])¶
- param parent:
Creates a new
QAudioProbe
class with aparent
. After setting the source to monitor withsetSource()
, theaudioBufferProbed()
signal will be emitted when audio buffers are flowing in the source media object.
- PySide2.QtMultimedia.QAudioProbe.audioBufferProbed(buffer)¶
- Parameters:
buffer –
PySide2.QtMultimedia.QAudioBuffer
- PySide2.QtMultimedia.QAudioProbe.flush()¶
- PySide2.QtMultimedia.QAudioProbe.isActive()¶
- Return type:
bool
Returns true if this probe is monitoring something, or false otherwise.
The source being monitored does not need to be active.
- PySide2.QtMultimedia.QAudioProbe.setSource(source)¶
- Parameters:
source –
PySide2.QtMultimedia.QMediaObject
- Return type:
bool
Sets the media object to monitor to
source
.If
source
is zero, this probe will be deactivated and this function wil return true.If the media object does not support monitoring audio, this function will return false.
The previous object will no longer be monitored. Passing in the same object will be ignored, but monitoring will continue.
- PySide2.QtMultimedia.QAudioProbe.setSource(source)
- Parameters:
source –
PySide2.QtMultimedia.QMediaRecorder
- Return type:
bool
Starts monitoring the given
mediaRecorder
.Returns true on success.
If there is no mediaObject associated with
mediaRecorder
, or if it is zero, this probe will be deactivated and this function wil return true.If the media recorder instance does not support monitoring audio, this function will return false.
Any previously monitored objects will no longer be monitored. Passing in the same (valid) object will be ignored, but monitoring will continue.
