Base class for an audio device with synchronised input and output channels.
Subclasses of this are used to implement different protocols such as DirectSound, ASIO, CoreAudio, etc.
To create one of these, you'll need to use the AudioIODeviceType class - see the documentation for that class for more info.
For an easier way of managing audio devices and their settings, have a look at the AudioDeviceManager class.

virtual |
Destructor.
Definition at line 31 of file juce_AudioIODevice.cpp.
Creates a device, setting its name and type member variables.
Definition at line 26 of file juce_AudioIODevice.cpp.
Closes and releases the device if it's open.

pure virtual |
Returns a mask showing which of the available input channels are currently enabled.
|
pure virtual |
Returns a mask showing which of the available output channels are currently enabled.
Returns the set of buffer sizes that are available.
Returns the set of sample-rates this device supports.
Returns the device's current physical bit-depth.
If the device isn't actually open, this value doesn't really mean much.
Returns the buffer size that the device is currently using.
If the device isn't actually open, this value doesn't really mean much.
Returns the sample rate that the device is currently using.
If the device isn't actually open, this value doesn't really mean much.
|
pure virtual |
Returns the names of all the available input channels on this device. To find out which of these are currently in use, call getActiveInputChannels().
Returns the device's input latency.
This is the delay in samples between some audio actually arriving at the soundcard, and the callback getting passed this block of data.
Returns the last error that happened if anything went wrong.
Returns the device's name, (as set in the constructor).
Definition at line 144 of file juce_AudioIODevice.h.
|
pure virtual |
Returns the names of all the available output channels on this device. To find out which of these are currently in use, call getActiveOutputChannels().
Returns the device's output latency.
This is the delay in samples between a callback getting a block of data, and that data actually getting played.
Returns the type of the device.
E.g. "CoreAudio", "ASIO", etc. - this comes from the AudioIODeviceType that created it.
Definition at line 150 of file juce_AudioIODevice.h.
|
virtualnoexcept |
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).
Definition at line 36 of file juce_AudioIODevice.cpp.
|
virtual |
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.
Definition at line 35 of file juce_AudioIODevice.cpp.
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.
Returns true if the device is still calling back.
The device might mysteriously stop, so this checks whether it's still playing.
|
pure virtual |
Tries to open the device ready to play.
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() |
On devices which support it, this allows automatic gain control or other mic processing to be disabled. If the device doesn't support this operation, it'll return false.
Definition at line 34 of file juce_AudioIODevice.cpp.
|
virtual |
Shows a device-specific control panel if there is one.
This should only be called for devices which return true from hasControlPanel().
Definition at line 38 of file juce_AudioIODevice.cpp.
|
pure virtual |
Starts the device actually playing.
This must be called after the device has been opened.
callback | the callback to use for streaming the data. |
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.
