Detailed Description

THERE IS NO SPOON

Ground-up rewrite of the XJ work logic. First we instantiate the dub cycle, which depends on the craft cycle operating on a separate thread. All Segment craft is persisted in memory, and the dub cycle is responsible for requesting crafted segments and specifically the picked audio, and then dubbing each output audio chunk.

Output audio chunks are dynamically sized. There is a default size, but the size is also determined by the duration of the segment. E.g., during gapless album output, the chunk will cut short if necessary to begin the next chunk at exactly the top of the following segment.

Member Function Documentation

computeActiveAudios()

std::set< ActiveAudio > DubWork::computeActiveAudios

(

unsigned long long

atChainMicros

)

Do dub frame

instead of mixing to file, mix to memory (produce to a BytePipeline) and let ship work consume the buffer use the same mixer from chunk to chunk, only changing the active audios

Ensure mixer has continuity of its processes/effects, e.g. the compressor levels at the last frame of the last chunk are carried over to the first frame of the next chunk

finish()

void DubWork::finish

(

)

Stop work

getMacroProgram()

std::optional< const Program * > DubWork::getMacroProgram

(

const Segment &

segment

)

const

Get the macro program for the given segment

Parameters

segment

for which to get program

Returns

macro program or empty if not yet available

getMainProgram()

std::optional< const Program * > DubWork::getMainProgram

(

const Segment *

segment

)

const

Get the main program for the given segment

Parameters

segment

for which to get program

Returns

main program or empty if not yet available

getSegmentAtChainMicros()

std::optional< const Segment * > DubWork::getSegmentAtChainMicros

(

long

atChainMicros

)

const

Get the segment at the given chain micros

Parameters

atChainMicros

the chain micros

Returns

the segment, or empty if not yet available

getSegmentAtOffset()

std::optional< const Segment * > DubWork::getSegmentAtOffset

(

int

offset

)

const

Get the segment at the given offset

Parameters

offset

the offset

Returns

the segment, or empty if not yet available

isFinished()

bool DubWork::isFinished

(

)

const

Check whether the craft work is finished

Returns

true if finished (not running)

runCycle()

std::set< ActiveAudio > DubWork::runCycle

(

unsigned long long

atChainMicros

)

Run the work cycle

setIntensityOverride()

void DubWork::setIntensityOverride

(

std::optional< float >

intensity

)

Set the intensity override to a value between 0 and 1, or null if no override

Parameters

intensity

the intensity override value, or null

start()

void DubWork::start

(

)

Start work
