na_play is a general playback program for playing sound files on a variety
62
of platforms and sound cards.
63
64
Currently, the following audio devices are supported:
65
66
<itemizedlist mark='@bullet'>
67
<listitem><para>sunaudio:</para><para>
68
8k ulaw direct to <filename>/dev/audio</filename> found on most Sun machines. This
69
is also found under Linux and FreeBSD, and possibly others. This
70
is the default if <function>netaudio</function> is not supported.
71
<listitem><para>netaudio:</para><para>
72
NCD's network transparent audio system (NAS). This allows
73
use of audio devices across a network. NAS has support for, Suns,
74
Linux, FreeBSD, HPs and probably other machines by now.
75
<listitem><para>sun16audio:</para><para>
76
This is only available on newer Sun workstations and has been
77
enabled at compile time. This provides
78
16bit linear PCM at various sample rates.
79
<listitem><para>linux16audio:</para><para>
80
This is only available on Linux workstations and has been enabled
81
at compile time. This provides
82
16bit linear PCM at various sample rates.
83
<listitem><para>freebsd16audio:</para><para>
84
This is only available on workstations running FreeBSD and has
85
been enabled at compile time. This provides
86
16bit linear PCM at various sample rates.
87
<listitem><para>mplayeraudio:</para><para>
88
This is only available under Windows NT 4.0 and Windows 95 and
89
has been enabled at compile time. This provides
90
16bit linear PCM at various sample rates.
91
<listitem><para>win32audio</para><para>
92
This is only available under Windows NT 4.0 and Windows 95 and
93
has been enabled at compile time. This provides
94
16bit linear PCM at various sample rates, playing the audio directly
95
rather than saving to a file as with mplayeraudio.
96
<listitem><para>irixaudio</para><para>
97
Audio support for SGI's IRIX 6.2.
98
<listitem><para>Audio_Command:</para><para>
99
Allows the specification of an arbitrary UNIX command to play
100
the waveform. This won't normally be used with <function>na_play</function> as
101
you could just use the command directly but is necessary with some
102
systems using the speech tools.
103
</itemizedlist>
104
</para>
105
106
<para>
107
The default audio is netaudio if it is supported. If not the platform
108
specific auido mode is the default (e.g. sun16audio, linux16audio,
109
freebsd16audio or mplayeraudio). If none of these is supported,
110
sunaudio is the default.
