Keywords: Get set WAVE volume .wav volume control sound level
Here's a snippet I used for my automatic mp3 volume adjuster program. It gets and sets the WAVE volume, not the overall volume, but might give you a step in the right direction. (I turned it into a quick example, 500 isn't a huge volume adjustment when it can go up to 32768.) DaDll=strcat(DirWindows(1),"WINMM.DLL") bin1 = BinaryAlloc(4) Gosub GetVolume Message(LeftVolumeAmount, RightVolumeAmount) LeftVolumeAmount = LeftVolumeAmount + 500 RightVolumeAmount = RightVolumeAmount - 500 Message(LeftVolumeAmount, RightVolumeAmount) Gosub SetVolume EXIT ****************************GetVolume****************************************** :GetVolume WaveErr = DllCall(DaDll, long:"waveOutGetVolume",long:0, lpbinary:bin1) if WaveErr != 0 Message("error in waveOutGetVolume:", WaveErr) exit endif BinaryEODSet(bin1, 4) LeftVolumeAmount = BinaryPeek2(bin1,0) RightVolumeAmount = BinaryPeek2(bin1,2) RETURN ****************************SetVolume****************************************** :SetVolume TempLeftVolumeAmount = LeftVolumeAmount TempRightVolumeAmount = RightVolumeAmount ;;Gosub AdjustBalance BinaryPoke2(bin1, 0, TempLeftVolumeAmount) BinaryPoke2(bin1, 2, TempRightVolumeAmount) NewVolume = BinaryPeek4(bin1, 0) WaveErr = DllCall(DaDll, long:"waveOutSetVolume",long:0, long:NewVolume) if WaveErr != 0 Message("error in waveOutSetVolume:", WaveErr) exit endif RETURN *******************************************************************************
