_sampleRateRange int[] _sampleRateRange;: Stores either all supported sample rates, or two values of lowest and highest supported sample rates if any value can be set without stepping. NOTE: It is not guaranteed, that at all sample ranges, all formats will be available.
_supportedFormats SampleFormat[] _supportedFormats;: Stores supported formats.
_nOfInputs short _nOfInputs;: Number of input channels, or zero if there's none.
_nOfOutputs short _nOfOutputs;: Number of output channels, or zero if there's none.
errCode int errCode;: The last error code if there's any, or 0. Shall not be set externally, although should not impede on operation.
_specs AudioSpecs _specs;: The audio specifications set and available to this device.
_shareMode AudioShareMode _shareMode;: Tells whether the device is in shared or exclusive mode. In some cases, this can be set, in others it's either shared or exclusive.
callback_onDeviceDisconnect void delegate() callback_onDeviceDisconnect;: Called when device is disconnected.
sampleRateRange int[] sampleRateRange [@property getter]: Returns the range of sample rates that this audio device supports. Might return null if it's enforced at audio spec request. NOTE: It is not guaranteed, that at all sample ranges, all formats will be available.
supportedFormats SampleFormat[] supportedFormats [@property getter]: Returns the range of audio formats that this audio device supports. Might return null if it's enforced at audio spec request. NOTE: It is not guaranteed, that at all sample ranges, all formats will be available.
nOfInputs short nOfInputs [@property getter]: Returns the number of input channels this device has, or zero if there's none, or -1 if it's enforced at audio spec request. NOTE: Depending on the backend, devices' inputs and outputs (or even different inputs and outputs) might show up as different devices.
nOfOutputs short nOfOutputs [@property getter]: Returns the number of output channels this device has, or zero if there's none, or -1 if it's enforced at audio spec request. NOTE: Depending on the backend, devices' inputs and outputs (or even different inputs and outputs) might show up as different devices.
specs AudioSpecs specs [@property getter]: Returns the currently set audio specifications.
shareMode AudioShareMode shareMode [@property getter]: Undocumented in source. Be warned that the author may not have intended to support it.
requestSpecs AudioSpecs requestSpecs(AudioSpecs reqSpecs, int flags): Sets the device's audio specifications to the closest possible specifications.
createOutputStream OutputStream createOutputStream(): Creates an OutputStream specific to the given driver/device, with the requested parameters, then returns it. Or null in case of an error, then it also sets errCode to a given error code. Might also set a separate error code variable, depending on the OS/backend.
