way (and even less any portable way) to maintain the list of library

with almost the same syntax (roughly an extra -M option).
Thru boxes are created with aucat, and corresponding MIDI port
names have the "aucat" prefix instead of "midithru". The old
device name will still work some time for backward compatibility.

audio. Now, both audio and midi code use the same SNDIO_DEBUG environment
variable to turn on/off DPRINTF's.

- make the ``-m mode'' option per subdevice, allowing
subdevices to be play-only or rec-only even if the
server is full-duplex
- add ``monitoring'' mode (with ``-m mon''). This is a
record-only stream from which played streams can be
recorded (kind of ``record what you hear'').
- allow MIDI devices to be subscribed to the controlling
MIDI port of the server, ie what midicat does (with -f
option), but using the -q option.
- add flow control to the protocol, and serialize clock
ticks (sio_onmove() calls) and data chunks. This should
fix certain full-duplex programs, broken with ``magic''
block/buffer size combinations.
- enable 3 block latency which is the minimum theoretical.
Make -z and -b options correspond to device parameters.
- make sio_getcap(3) the same for aucat and sun backends,
ie return whatever is supported (``everything'' in the
aucat case, since everything is actulally supported).
aucat (player):
- enable ``-m mode'' option to select between monitoring
and recording when ``-o file'' is used.
- plug MIDI code to non-server codepath. The MIDI control
device is specified with the ``-q device'' option, as in
server mode.
- impliment lseek()'ing within files (controlled
through MIDI). Necessary to use aucat with a MIDI
sequencer.
midicat (thrubox):
- rename ``-f'' flag to ``-q'', so it has the
same name as in aucat (-f is still working)

cannot cooperate with other programs. The aim of this change is
to allow any program to send midi data to other programs as they
were midi hardware. For instance, this change should solve the
longstanding problem of using a midi sequencer with software
synthesizers. More precisely:
- new midicat(1) utility (actually hardlink to aucat(1)).
it creates software midi thru boxes, allowing programs
to send midi messages to other programs as they were
midi(4) hardware.
- new midi api in libsndio (see mio_open(3)), to access
midi(4) devices and midicat(1) sockets in a uniform way.
- new device naming scheme <service>:<unit>[.<option>],
common to audio and midi.
- new sndio(7) manual describing concepts and naming
The current audio device naming still works, but people having
scripts or configuration files containing device names could read
the sndio(7) man page and slowly start updating device names.

the program-part of the buffer size, ie the part that is subject to
underruns. Useful for apps like cdio(1) that don't have their own
rings, or to apps that have a minimum ring size constraint. Setting
the ``bufsz'' parameter becomes deprecated.

sio_onvol(3) functions. The audio(4) backend tries to use the
inputs.dac, outputs.dac, outputs.output and outputs.master
controls (in this order). Add a sample file in
regress/lib/libsndio/vol/vol.c
|
|
|
|
and thus remove the ugly rate <-> block-size table from
sio_setpar(3). Handle the block size negociation in aucat(1), since
it has few constrains the code is overally simpler.
