The default is \fB{/artist}{/album}{/title}{ext}\fR.
.TP
+.B backend \fINAME\fR
+Selects the backend use by the speaker process. The following options are
+available:
+.RS
+.TP
+.B alsa
+Use the ALSA API. This is only available on Linux systems, on which it is the
+default.
+.TP
+.B command
+Execute a command. This is the default if
+.B speaker_command
+is specified, or (currently) on non-Linux systems.
+.TP
+.B network
+Transmit audio over the network. This is the default if
+\fBbroadcast\fR is specified.
+.RE
+.TP
+.B broadcast \fIADDRESS\fR \fIPORT\fR
+Transmit sound data to \fIADDRESS\fR using UDP port \fIPORT\fR. This implies
+\fBbackend network\fR.
+.TP
+.B broadcast_from \fIADDRESS\fR \fIPORT\fR
+Sets the (local) source address used by \fBbroadcast\fR.
+.TP
.B channel \fICHANNEL\fR
The mixer channel that the volume control should use. Valid names depend on
your operating system and hardware, but some standard ones that might be useful
The interval at which the preferences log file will be synchronised. Defaults
to 3600, i.e. one hour.
.TP
+.B queue_pad \fICOUNT\fR
+The target size of the queue. If random play is enabled then randomly picked
+tracks will be added until the queue is at least this big.
+.TP
+.B sample_format \fIBITS\fB/\fIRATE\fB/\fICHANNELS
+Describes the sample format expected by the \fBspeaker_command\fR (below). The
+components of the format specification are as follows:
+.RS
+.TP 10
+.I BITS
+The number of bits per sample. Optionally, may be suffixed by \fBb\fR or
+\fBl\fR for big-endian and little-endian words. If neither is used the native
+byte order is assumed.
+.TP
+.I RATE
+The number of samples per second.
+.TP
+.I CHANNELS
+The number of channels.
+.PP
+The default is
+.BR 16/44100/2 .
+.RE
+.TP
.B signal \fINAME\fR
Defines the signal to be sent to track player process groups when tracks are
scratched. The default is \fBSIGKILL\fR.
Signals are specified by their full C name, i.e. \fBSIGINT\fR and not \fBINT\fR
or \fBInterrupted\fR or whatever.
.TP
+.B sox_generation \fB0\fR|\fB1
+Determines whether calls to \fBsox\fR(1) should use \fB-b\fR, \fB-x\fR, etc (if
+the generation is 0) or \fB-\fIbits\fR, \fB-L\fR etc (if it is 1). The default
+is 0.
+.TP
+.B speaker_command \fICOMMAND
+Causes the speaker subprocess to pipe audio data into shell command
+\fICOMMAND\fR, rather than writing to a local sound card. The sample format is
+determine by
+.B sample_format
+above.
+.IP
+Note that if the sample format is wrong then
+.BR sox (1)
+is invoked to translate it. If
+.B sox
+is not installed then this will not work.
+.TP
.B restrict \fR[\fBscratch\fR] [\fBremove\fR] [\fBmove\fR]
Determine which operations are restricted to the submitter of a
track. By default, no operations are restricted, i.e. anyone can
name and \fBext\fR which is the filename extension, including the initial dot
(or the empty string if there is not extension).
