Detailed Description

Represents a type of audio driver, such as DirectSound, ASIO, CoreAudio, etc.

To get a list of available audio driver types, use the AudioDeviceManager::createAudioDeviceTypes() method. Each of the objects returned can then be used to list the available devices of that type. E.g.

myAudioDeviceManager.createAudioDeviceTypes (types);
for (int i = 0; i < types.size(); ++i)
{
String typeName (types[i]->getTypeName()); // This will be things like "DirectSound", "CoreAudio", etc.
types[i]->scanForDevices(); // This must be called before getting the list of devices
StringArray deviceNames (types[i]->getDeviceNames()); // This will now return a list of available devices of this type
for (int j = 0; j < deviceNames.size(); ++j)
{
AudioIODevice* device = types[i]->createDevice (deviceNames [j]);
...
}
}
virtual StringArray getDeviceNames(bool wantInputNames=false) const =0
const String & getTypeName() const noexcept

For an easier way of managing audio devices and their settings, have a look at the AudioDeviceManager class.

Referenced by juce::AudioDeviceManager::createAudioDeviceTypes().

◆ createDevice()

virtual AudioIODevice * juce::AudioIODeviceType::createDevice ( const String outputDeviceName,
const String inputDeviceName 
)
pure virtual

Creates one of the devices of this type.

The deviceName must be one of the strings returned by getDeviceNames(), and scanForDevices() must have been called before this method is used.

◆ getDefaultDeviceIndex()

virtual int juce::AudioIODeviceType::getDefaultDeviceIndex ( bool  forInput) const
pure virtual

Returns the name of the default device.

This will be one of the names from the getDeviceNames() list.

Parameters
forInputif true, this means that a default input device should be returned; if false, it should return the default output

◆ getDeviceNames()

virtual StringArray juce::AudioIODeviceType::getDeviceNames ( bool  wantInputNames = false) const
pure virtual

Returns the list of available devices of this type.

The scanForDevices() method must have been called to create this list.

Parameters
wantInputNamesfor devices which have separate inputs and outputs this determines which list of names is returned

◆ getIndexOfDevice()

virtual int juce::AudioIODeviceType::getIndexOfDevice ( AudioIODevice device,
bool  asInput 
) const
pure virtual

Returns the index of a given device in the list of device names. If asInput is true, it shows the index in the inputs list, otherwise it looks for it in the outputs list.

◆ getTypeName()

const String & juce::AudioIODeviceType::getTypeName ( ) const
inlinenoexcept

Returns the name of this type of driver that this object manages.

This will be something like "DirectSound", "ASIO", "CoreAudio", "ALSA", etc.

Definition at line 69 of file juce_AudioIODeviceType.h.

◆ hasSeparateInputsAndOutputs()

virtual bool juce::AudioIODeviceType::hasSeparateInputsAndOutputs ( ) const
pure virtual

Returns true if two different devices can be used for the input and output.

◆ removeListener()

void juce::AudioIODeviceType::removeListener ( Listener listener)

Removes a listener that was previously added with addListener().

Definition at line 37 of file juce_AudioIODeviceType.cpp.

◆ scanForDevices()

pure virtual

Refreshes the object's cached list of known devices.

This must be called at least once before calling getDeviceNames() or any of the other device creation methods.
