Detailed Description

Ambisonic encoder with distance cues.

This is similar to a normal the ambisonic encoder, but takes the source's distance into account, delaying the signal, adjusting its gain, and implementing "W-Panning"(interior effect). If distance is not an issue, then use CAmbisonicEncoder which is more efficient.

Constructor & Destructor Documentation

CAmbisonicEncoderDist::CAmbisonicEncoderDist	(	AmbInt	nOrder = DEFAULT_ORDER,
		AmbInt	b3D = DEFAULT_HEIGHT,
		AmbInt	nSampleRate = DEFAULT_SAMPLERATE
	)

Constructor that allows for the format to be specified. If the format arguments are not specified, the values set for DEFAULT_ORDER, and DEFAULT_HEIGHT, will be used instead, and a default sample rate of DEFAULT_SAMPLERATE.

Member Function Documentation

void CAmbisonicEncoderDist::Create	(	AmbInt	nOrder,
		AmbInt	b3D,
		AmbInt	nSampleRate
	)			[virtual]

Re-create the object for the given configuration. Previous data is lost.

Reimplemented from CAmbisonicSource.

void CAmbisonicEncoderDist::Reset

(

)

[virtual]

Resets members such as delay lines.

Reimplemented from CAmbisonicSource.

void CAmbisonicEncoderDist::Refresh

(

)

[virtual]

Refreshes coefficients.

Reimplemented from CAmbisonicEncoder.

void CAmbisonicEncoderDist::Process	(	AmbFloat *	pfSrc,
		AmbInt	nSamples,
		CBFormat *	pBFDst
	)

Encode mono stream to B-Format.

Reimplemented from CAmbisonicEncoder.

void CAmbisonicEncoderDist::SetRoomRadius

(

AmbFloat

fRoomRadius

)

Set the radius of the intended playback speaker setup which is used for the interior effect (W-Panning).

AmbFloat CAmbisonicEncoderDist::GetRoomRadius

(

)

Returns the radius of the intended playback speaker setup, which is used for the interior effect (W-Panning).
