Description
AgsAudio organizes AgsChannel objects either as input or output and is responsible of their alignment. The class can contain AgsRecall objects in order to perform computation on all channels or in audio context. Therefor exists AgsRecyclingContext acting as tree context.
At least one AgsRecallID is assigned to it and has one more if
AGS_AUDIO_OUTPUT_HAS_RECYCLING
is set as flag.
It hosts common storage objects like AgsNotation, AgsAutomation and AgsWave.
In order to make use of AgsNotation or AgsWave you have to set
AGS_AUDIO_OUTPUT_HAS_RECYCLING
.
Make sure you have set the matching ags_audio_set_ability_flags()
. This is going to setup threads per matching
AgsSoundScope scope. See AgsPlaybackDomain and AgsPlayback.
Threads are usually run per AgsAudio with AGS_AUDIO_OUTPUT_HAS_RECYCLING
.
This are instruments, samplers, synthesizer, step sequencers or wave players.
In other words the producer of your AgsAudioSignal.
The dispatcher function ags_audio_recursive_run_stage()
is invoked as per
ags_channel_recursive_run_stage()
per output
channel.
playback-domain
property.
You have in general one AgsPlaybackDomain referring one AgsAudio and one AgsPlayback referring one AgsChannel.
AGS_AUDIO_SYNC
and AGS_AUDIO_ASYNC
AGS_AUDIO_SYNC
means channels go straight from input line to matching
output line.
AGS_AUDIO_ASYNC
means input channels are bundled in output i.e. many
inputs of the same audio channel arrive at one output channel of the
same audio channel.
AGS_AUDIO_SYNC
and AGS_AUDIO_ASYNC
combined is only available if
AGS_AUDIO_OUTPUT_HAS_RECYCLING
is set. It is actually the same behaviour
as AGS_AUDIO_ASYNC
except you can have more than one output pad.
output-soundcard
and input-soundcard
properties are
output-sequencer
and input-sequencer
properties are
You may add AgsNotation objects using ags_audio_add_notation()
. Make sure
the AgsNotation timestamp offset occurs only once per audio channel and is
correct padded using AGS_NOTATION_DEFAULT_OFFSET
.
You may add AgsWave objects using ags_audio_add_wave()
. Make sure the
AgsWave timestamp offset occurs only once per line and is correct padded
using relative offset. The relative offset is calculated as following:
relative_offset = AGS_WAVE_DEFAULT_BUFFER_LENGTH
* samplerate;
You may add AgsAutomation objects using ags_audio_add_automation()
. Make
sure AgsAutomation timestamp offset occurs only once per channel type and
line. If the context of the automation is AgsAudio channel-type
is
G_TYPE_NONE and line
is 0.
To modify the alignment of output or input channels use
ags_audio_set_audio_channels()
and to increase pads ags_audio_set_pads()
.
There is a playback and recall context for hosting AgsRecall implementations.
Usually you instantiate a recall for both contices. See play
and recall
properties.
