<H3>Parameters</H3>
<TABLE>
<TR VALIGN=top><TD><I>mixrate</I></TD>
<TD>Output rate in hz between 4000 and 65535. Any thing outside this will cause<BR>
the function to fail and return FALSE.<BR>
PS2 Note. Only rates of 24000 and 48000 are supported.<BR>
PSP Note. Only rates of 22050 and 44100 are supported.<BR>
SmartPhone Note. Use 22050 or the operating system may crash outside of the control of fmod.<BR>
</TD><TR VALIGN=top><TD><I>maxchannels</I></TD>
<TD>Maximum number of SOFTWARE channels available.<BR>
The number of HARDWARE channels is autodetected. The total number of channels available (hardware and software) after initialization can be found with FSOUND_GetMaxChannels. <BR>
Having a large number of maxchannels does not adversely affect cpu usage, but it means it has the POTENTIAL to mix a large number of channels, which can have an adverse effect on cpu usage.<BR>
1024 is the highest number that can be set. Anything higher will return an error.<BR>
</TD><TR VALIGN=top><TD><I>flags</I></TD>
<TD>See FSOUND_INIT_FLAGS. Controls some global or initialization time aspects of playback.<BR>
</TD></TABLE>
<H3>Return Value</H3>
On success, TRUE is returned.<BR>
On failure, FALSE is returned.<BR>
<H3>Remarks</H3>
You do not have control over how many hardware channels are available to you. In a lot of<BR>
cases it may be 0 (the sound card does not have the ability to supply hardware channels).<BR>
This is why it is usually a good idea to supply FSOUND_Init with a good number of software<BR>
channels to fall back onto, for example 32.<BR>
Hardware channels are 3D hardware channels only. There is no benefit in supporting hardware<BR>
for 2d playback of sound effects. With todays machines and FMOD's superior mixing routines,<BR>
FMOD's software engine can sometimes be faster than the driver's hardware support! <BR>
