.SH "NAME"
jack-dl \- JACK shared library dsp loader
.SH "SYNOPSIS"
.sp
jack\-dl [options]
.SH "OPTIONS"
.sp
\fB\-b\fR : Set the number of buffers (default=8)\&. \fB\-c\fR : Set the number of input and output channels (default=8)\&. \fB\-k\fR : Set the number of control buses (default=64)\&. \fB\-p\fR : Set the udp port number (default=57190)\&.
.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 \-\-\-\-\-\-\- \-\-\-\-\-\-\-\-\- \-\-\-\-\-\-\-\-\-\-\- /b_alloc id::int frames::int channels::int buffer allocate /c_set index::int value::float control set /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\&.
