	`property processDataInPlace default false;`

Description

Methods

	`constructor Create(owner: tComponent); override;`

	`function convertOutFloat2PCM(out buf: pointer): int; override;`
Converts DSP DLib output float buffer(s) to PCM plain buffer, and returns its size in bytes.

	`function getNumFreq(): int; override;`
Num of freqs is one less than numBands in MBSP, so we override this function

	`procedure AfterConstruction(); override;`

	`procedure BeforeDestruction(); override;`

Properties

	`property onRawSamplesAvailable: unavclRawSamplesAvailable read f_onRawSamplesAvail write f_onRawSamplesAvail;`
Fired when raw multi-band samples are ready.

	`property passThrough[band:unsigned]: bool read getPT write setPT;`
Pass-through value for a specific band.

	`property processDataInPlace default false;`
MBSP splits the audio into bands only when processDataInPlace is false, so we make it default.
