//extensions to sound():
//- channel may be in the range from -128 to 127; channels -128 to 0 are "auto",
// i.e. support multiple sounds at once, but cannot be stopped/restarted
-//- a speed parameter has been reserved for later addition of pitch shifting.
-// it MUST be set to 0 for now, meaning "no pitch change"
+//- a value 0 in the speed parameter means no change; otherwise, it is a
+// percentage of playback speed ("pitch shifting"). 100 is normal pitch, 50 is
+// half speed, 200 is double speed, etc. (DP_SND_SOUND7_WIP2)
//- the flag SOUNDFLAG_RELIABLE can be specified, which makes the sound send
// to MSG_ALL (reliable) instead of MSG_BROADCAST (unreliable, default);
// similarily, SOUNDFLAG_RELIABLE_TO_ONE sends to MSG_ONE
