Access_Key_ID	SOUND4 AWS access ID
Access_Key_Secret	SOUND4 AWS access Secret
save_path	Path where we can load/save the configuration
json_port	Optional json listening port

Definition at line 917 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetAudio()

template<typename T >

unsigned int sound4::bigvoice::dyn::CInstance::GetAudio	(	T *	payload,
		unsigned int	max_nFrame
	)

inlineprotected

Definition at line 1342 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetBufferIn()

std::array< float, InputSampleSize > & sound4::bigvoice::dyn::CInstance::GetBufferIn ( )

inline

Gets the input buffer used in ProcessAudio

Input has GetAudioInputCount() * GetChannelCount() channels

Each sample is a native 32-bit floating-point number where 1.0 is full scale. Channels are interlaced, so the buffers are [L0,R0,L1,R1,...,Ln,Rn] (L=Left, R=Right)

In case of multiple audio input/output, buffer is [aL0,aR0,bL0,bR0,...,aLn,aRn,bLn,bRn]

Definition at line 1189 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetBufferOut()

std::array< float, OutputSampleSize > & sound4::bigvoice::dyn::CInstance::GetBufferOut ( )

inline

Gets the output buffer used in ProcessAudio

Output has GetAudioOutputCount() * GetChannelCount() channels

Each sample is a native 32-bit floating-point number where 1.0 is full scale. Channels are interlaced, so the buffers are [L0,R0,L1,R1,...,Ln,Rn] (L=Left, R=Right)

In case of multiple audio input/output, buffer is [aL0,aR0,bL0,bR0,...,aLn,aRn,bLn,bRn]

Definition at line 1206 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetChunkFrames()

unsigned int sound4::bigvoice::dyn::CInstance::GetChunkFrames ( )

inline

Get the number of audio frames in each chunk of processing.

The value reflects the frames_per_chunk parameter passed to Create

Returns: the number of audio frames in each chunk of processing

Definition at line 960 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetEstimatedDelay()

unsigned int sound4::bigvoice::dyn::CInstance::GetEstimatedDelay ( )

inline

Gets an estimated delay of current processing

See also: bigvoice_GetEstimatedDelay

Definition at line 1173 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetMetadataInfos()

std::vector< std::tuple< std::string, std::string > > sound4::bigvoice::dyn::CInstance::GetMetadataInfos ( )

inline

Get information on known metadata keys.

Returns: a list of {key,description} of known metadata used in process and extensions.

Definition at line 1049 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetParam()

std::string sound4::bigvoice::dyn::CInstance::GetParam ( const std::string & name )

inline

Gets a parameter value

See also: bigvoice_GetParameter

Definition at line 855 of file sound4.bigvoice.cl_dyn.hpp.

◆ GetWebServerAppHealth()

void sound4::bigvoice::dyn::CInstance::GetWebServerAppHealth	(	int &	httpcode,
		std::string &	contenttype,
		std::string &	content
	)

inline

Get the web server /apphealth status info

Definition at line 1123 of file sound4.bigvoice.cl_dyn.hpp.

◆ IsOk()

bool sound4::bigvoice::dyn::CInstance::IsOk ( ) const

inline

Returns true if an instance has been created and not stopped.

Definition at line 837 of file sound4.bigvoice.cl_dyn.hpp.

◆ NewClient()

std::shared_ptr< CClient > sound4::bigvoice::dyn::CInstance::NewClient ( )

inline

Creates a low-level JSON client

See also: JSON syntax

Returns: a new client to communicate with the processing

Definition at line 1328 of file sound4.bigvoice.cl_dyn.hpp.

◆ OnUpdateThreadStart()

virtual void sound4::bigvoice::dyn::CInstance::OnUpdateThreadStart ( )

inlinevirtual

Definition at line 1071 of file sound4.bigvoice.cl_dyn.hpp.

◆ OnUpdateThreadStop()

virtual void sound4::bigvoice::dyn::CInstance::OnUpdateThreadStop ( )

inlinevirtual

Definition at line 1073 of file sound4.bigvoice.cl_dyn.hpp.

◆ operator=()

CInstance & sound4::bigvoice::dyn::CInstance::operator= ( const CInstance & )

delete

◆ PresetManager_InformChange()

void sound4::bigvoice::dyn::CInstance::PresetManager_InformChange	(	const std::filesystem::path &	relative_path,
		PresetChange_Kind	change_kind
	)

inline

Inform that a change happened in the storage. This must be used only in conjonction with SetPresetManager

Parameters

relative_path	The path which changed, relative to the root storage
change_kind	What happened to this path

Definition at line 974 of file sound4.bigvoice.cl_dyn.hpp.

◆ ProcessAnyAudio()

template<typename T >

std::vector< T > sound4::bigvoice::dyn::CInstance::ProcessAnyAudio ( const std::vector< T > input )

inline

Process audio (different formats, less optimized)

Supports for int16_t, int32_t and float (32) in native endianness

Attention: the return count is independent from the input count due to BIGVOICE_AUDIOFRAME_COUNT

Template Parameters

T	the C type for one audio sample

Parameters

input audio to process

Returns: processed audio

Definition at line 1254 of file sound4.bigvoice.cl_dyn.hpp.

◆ ProcessAudio()

void sound4::bigvoice::dyn::CInstance::ProcessAudio ( )

inline

Process one audio chunk, from GetBufferIn() to GetBufferOut()

See also: bigvoice_ProcessAudio

Definition at line 1217 of file sound4.bigvoice.cl_dyn.hpp.

◆ ProcessAudio_Planar()

void sound4::bigvoice::dyn::CInstance::ProcessAudio_Planar	(	float const const	input,
		float const	output
	)

inline

Process one audio chunk, but with planar audio

Each sample is a native 32-bit floating-point number where 1.0 is full scale. Channels are NOT interlaced, so the buffers are arrays of planar audio : [ [L0,L1,...,Ln] , [R0,R1,...,Rn] ] (L=Left, R=Right)

In case of multiple audio input/output, buffer are [ [aL...], [aR...], [bL...], [bR...], ... ]

See also: bigvoice_ProcessAudio_Planar

Parameters

input	has GetAudioInputCount() * GetChannelCount() channels
output	has GetAudioOutputCount() * GetChannelCount() channels

Definition at line 1236 of file sound4.bigvoice.cl_dyn.hpp.

◆ SetBus()

void sound4::bigvoice::dyn::CInstance::SetBus ( const CBus & bus )

inline

Set the instance bus

Definition at line 867 of file sound4.bigvoice.cl_dyn.hpp.

◆ SetMetadata()

void sound4::bigvoice::dyn::CInstance::SetMetadata	(	const std::string &	key,
		const char *	value
	)

inline

Adds the specific metadata to the process.

It can come from any thread, and will be used as soon as possible. Setting a null value erase the metadata, which is different from setting an empty string.

Parameters

key	the metadata key If key contains a dot (like wm.KEY), it will be sent only to the matching plugin (ie wm here) without the prefix (ie KEY here) Use empty prefix for routing to main only.
value	the metadata value or nullptr to erase it.
