Implements juce::AudioIODevice.

◆ getInputLatencyInSamples()

int juce::ASIOAudioIODevice::getInputLatencyInSamples ( )

◆ getOutputLatencyInSamples()

int juce::ASIOAudioIODevice::getOutputLatencyInSamples ( )

◆ getSampleRate()

double juce::ASIOAudioIODevice::getSampleRate ( ) const

inlineprivate

◆ getXRunCount()

int juce::ASIOAudioIODevice::getXRunCount ( ) const

inlineoverridevirtualnoexcept

Returns the number of under- or over runs reported by the OS since playback/recording has started.

This number may be different than determining the Xrun count manually (by measuring the time spent in the audio callback) as the OS may be doing some buffering internally - especially on mobile devices.

Returns -1 if playback/recording has not started yet or if getting the underrun count is not supported for this device (Android SDK 23 and lower).

Reimplemented from juce::AudioIODevice.

◆ hasControlPanel()

bool juce::ASIOAudioIODevice::hasControlPanel ( ) const

inlineoverridevirtual

True if this device can show a pop-up control panel for editing its settings.

This is generally just true of ASIO devices. If true, you can call showControlPanel() to display it.

Reimplemented from juce::AudioIODevice.

◆ initDriver()

String juce::ASIOAudioIODevice::initDriver ( )

inlineprivate

◆ isOpen()

bool juce::ASIOAudioIODevice::isOpen ( )

inlineoverridevirtual

Returns true if the device is still open.

A device might spontaneously close itself if something goes wrong, so this checks if it's still open.

Implements juce::AudioIODevice.

◆ isPlaying()

bool juce::ASIOAudioIODevice::isPlaying ( )

inlineoverridevirtual

Returns true if the device is still calling back.

The device might mysteriously stop, so this checks whether it's still playing.

Implements juce::AudioIODevice.

inlineprivate

◆ open()

String juce::ASIOAudioIODevice::open	(	const BigInteger &	inputChannels,
		const BigInteger &	outputChannels,
		double	sampleRate,
		int	bufferSizeSamples )

inlineoverridevirtual

Tries to open the device ready to play.

Parameters

inputChannels	a BigInteger in which a set bit indicates that the corresponding input channel should be enabled
outputChannels	a BigInteger in which a set bit indicates that the corresponding output channel should be enabled
sampleRate	the sample rate to try to use - to find out which rates are available, see getAvailableSampleRates()
bufferSizeSamples	the size of i/o buffer to use - to find out the available buffer sizes, see getAvailableBufferSizes()

Returns: an error description if there's a problem, or an empty string if it succeeds in opening the device

inlineprivate

◆ showControlPanel()

bool juce::ASIOAudioIODevice::showControlPanel ( )

inlineoverridevirtual

Shows a device-specific control panel if there is one.

This should only be called for devices which return true from hasControlPanel().

Reimplemented from juce::AudioIODevice.

◆ start()

void juce::ASIOAudioIODevice::start ( AudioIODeviceCallback * callback )

inlineoverridevirtual

Starts the device actually playing.

This must be called after the device has been opened.

Parameters

callback the callback to use for streaming the data.

See also: AudioIODeviceCallback, open

Implements juce::AudioIODevice.

◆ stop()

void juce::ASIOAudioIODevice::stop ( )

inlineoverridevirtual

Stops the device playing.

Once a device has been started, this will stop it. Any pending calls to the callback class will be flushed before this method returns.

Implements juce::AudioIODevice.

◆ timerCallback()

void juce::ASIOAudioIODevice::timerCallback ( )

inlineoverridevirtual

The user-defined callback routine that actually gets called periodically.

It's perfectly ok to call startTimer() or stopTimer() from within this callback to change the subsequent intervals.

Implements juce::Timer.
