That snippet (with "SetAudio" changed to "Set Audio") has the volume the same for both plays - too low. It doesn't go up to normal for the second play like the PB code does.

Same. Equal but volume too low.

Just encase there's some doubt regarding it not being PB fault.
If you played that file with your associated media player, and the playback begins with the low volume and increases. We know PureBasic isn't responsible then.

Yup that's what happened. Definitely nothing to do with PB.

I wish I was with Windows 8.1. I would see if this issue is shared.

I'm grasping at straws... Have you tried with another set of speakers or even with an headset?

Nah I don't really care. As long as my code doesn't have a bug and PB doesn't have a bug I'm fine.

It might be a problem with one of the sound affects faulting.
- 1) Right-click on Volume systray Icon
2) Select "Playback devices"
3) Double click on "Speakers"
4) Click the 'Enhancements' tab
5) Check "Disable all sound effects"
6) Click OK.
Wait couple of seconds and test.

i have some file mono, 8 bit wav. how i can make some change volume of it? i try to make some like this:
Code: Select all
Number.a = ReadAsciiCharacter(0)
limit = 5
if Number > $80+limit
Number - limit
elseif Number < $80-limit
Number + limit
endif
WriteAsciiCharacter(1, Number)
when limit is 5 - it give just little sound down, but when i set to more value 30 for more silence - it play more silence, but add some hiss effect. how to correct make this lower or louder sound?

Code: Select all
Number.a = ReadAsciiCharacter(0)
Number = (Number - 127.5) * 0.25 + 127.5 ; scaling = 0.25
WriteAsciiCharacter(1, Number)
