On RISC OS, Vice offers two sound devices, VIDC (asynchronous) and VIDC Sync
6
(your guess), and two sound models, 8bit and 16bit. The asynchronous device
7
allows reducing latency (-> buffer size) considerably without risking dropouts
8
and is therefore ideal for playing games with SFX, that's why it's the default
9
for the ``real'' emulators (not the VSID player). Unfortunately, Vice wasn't
10
written with asynchronous sound in mind and therefore it's kind of a hack that
11
doesn't work well with SID music (doesn't work at all with reSID!), i.e. you
12
should select the synchronous sound device if you want music to sound good,
13
that's why the synchronous device is the default device in VSID; in that case
14
you need a rather large sound buffer size to minimize dropouts, though (say
15
0.35 seconds minimum, with all the problems this causes like delayed sound etc;
16
besides Vice doesn't react too well to sudden speed changes in synchronous
18
If we had really fast CPUs on RISC OS, I'd just advice using the synchronous
19
device and a buffer size of 0.1 seconds, but that doesn't work well ATM. Choose
20
whichever device best fits your needs, using the asynchronous one for playing
21
games (do not use reSID in that case!) to get the sound when you press the button
22
and the synchronous one if you want to listen to music.
24
8bit sound was the old system using logarithmic samples, but it was superceded
25
in RISC OS 3.5 (to be precise the hooks for 16bit sound were introduced in RO3.5,
26
but not every machine had the necessary hardware too). 16bit sound is available
27
on the newer machines (type ``*help SoundSystem'' at the CLI to find out whether
28
your machine supports it). Since version 1.7 Vice (or rather the DigitalRenderer
29
module included) has also been able to use 16bit mode and you're advised to use
30
it if your machine has the necessary hardware. It's off by default, however,
31
because it's not standard on all RISC OS machines and I want Vice to run out
32
of the box on as many machines as possible. You can choose 8bit/16bit sound
33
from the sound configuration window.

41
favourites with an exclamation mark. Look for these SIDs in the High Voltage
42
SID Collection (HVSC) and use them in VSID)
