Detailed Description

Provides a callback function that is called with resampled audio data.

IOResampler class.

Supports mono and stereo input and stereo output.

The IOResampler contains two resamplers and it works like this:

[Input audio @ source sample rate] - [Resampler] - [Callback function @ callback sample rate] - [Resampler] - [Output audio @ source sample rate]

Number of frames is never changed during the process call. Returned audio data might contain zero values initially.

Constructor & Destructor Documentation

IOResampler()

switchboard::IOResampler::IOResampler	(	const uint	sourceSampleRate,
		const uint	callbackSampleRate,
		const IOResamplerCallbackFunction	callback )

Creates an IOResampler instance.

Parameters

sourceSampleRate	The source sample rate.
callbackSampleRate	The sample rate of the audio data that will be passed to the callback function.
callback	The callback function that processed the resampled audio data.

process()

bool switchboard::IOResampler::process	(	float **	buffers,
		const bool	inputIsMono,
		const uint	numberOfFrames,
		void *	userPointer )

Audio process function of IOResampler.

Parameters

buffers	[inout] The buffers containing the audio data.
inputIsMono	Must be true if the buffers parameter contains mono data, false otherwise.
numberOfFrames	Number of frames in the buffers parameter.
userPointer	Custom pointer value that will be passed to the callback function.

Returns

True if audio data has been written to buffers, false otherwise.
