.SH "DESCRIPTION"
|
|
.sp
|
|
jack\-dl loads dsp algorithms from shared libraries and allows user interaction with the executing graph\&. Commands are sent as OSC packets over a UDP connection\&.
|
|
.sp
|
|
The dsp graph code must provide three functions:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
size_t (*dsp_memreq)();
|
|
void (*dsp_init)(void *);
|
|
void (*dsp_step)(void *,int);
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
jack\-dl accepts the OSC commands:
|
|
.sp
|
|
Command - Arguments (Description)
|
|
.br
|
|
/b_alloc - id::int frames::int channels::int (buffer allocate)
|
|
.br
|
|
/c_set - index::int value::float (control set)
|
|
.br
|
|
/g_load - object\-file::file\-path (graph load)
|
|
.sp
|
|
jack\-dl consults the JACK_DL_CONNECT_TO and JACK_DL_CONNECT_FROM environment variables\&.
|
|
.sp
|
|
jack\-dl implements only a subset of the OSC protocol\&. In particular it does not implement the patten matching rules and does not implement a scheduler for incoming messages\&.
|
|
.sp
|
|
jack\-dl drops all unrecognized incoming packets\&.
