Typedef Documentation

typedef Function<void ( SoundDevice& device, const SoundBuffer& inputBuffer, Size numInputSamples, const Time& time )> om::sound::devices::SoundInputCallback

Define a short name for the type of the function object that is used to recieve audio from SoundDevice objects.

The implementor of the function can read the specified number of samples from the input buffer and use them in some way.

The given time represents the absolute time of the first sample in the buffer, measured relative to the Epoch, 1970-01-01 00:00:00 +0000 (UTC).

typedef Function<Size ( SoundDevice& device, SoundBuffer& outputBuffer, Size numOutputSamples, const Time& time )> om::sound::devices::SoundOutputCallback

Define a short name for the type of the function object that is used to send audio to SoundDevice objects for output.

The implementor should write the specified number of samples to the output buffer for each channel and then return the number of samples that were successfully written to the output buffer.

The given time represents the absolute time of the first sample in the buffer, measured relative to the Epoch, 1970-01-01 00:00:00 +0000 (UTC).

typedef Function<void ( MIDIDevice& device, const MIDIBuffer& messages )> om::sound::devices::MIDIInputCallback

Define a short name for the type of the function object that is used to recieve MIDI from MIDIDevice objects.

The implementor of the function can then use the given MIDI messages to perform some action.
