Hello,
when i play a sound file like mp3 or wav with MediaPlayer or anything like
this, i would like to get the volume level of the sound card in real time.
The data is then sent to the serial port. How do i get this data. I tried to
find some samples in msdn or internet but i couldn t find any useful code.
There is the winmm.dll which supports calls to waveIn and waveOut but all
the samples use them to set or get the master volume. That is not what i
need. I thought i found a sample in msdn, but this doesnt work. Can anybody
help me?? 3 6735
Hi,
Maybe this will help. The class has some volume control method. http://www.mentalis.org/soft/class.qpx?id=1

Thank you Ken, but this class also uses the Properties to get or set the
master volume. They do not provide real time data. I know that there is a
way, because there is an ocx which shows as an real-time led but without
getting the data. Perhaps there is an other solution?

Hi, unfortunately I cannot offer a solution, but I think you're referring to
the output level, not the actualy volume of output, e.g. the amplitude of
the sound coming out the speaker at any one instant in time.
I tried doing this once, but I fell flat on my face as there was
limited/incomplete examples around the net, having said that, this was about
2 years ago, so you might want to check again.
Anywho, I eventually found that the most results tended around something
called a "VU Meter", or "audio level"
Happy Googling :)

Is there a library in python that has methods applicable to volume(in terms of sound) of a given file? For example if it can check if the sound volume of a file is on the same level for the entire file duration?; or if the sound volume increases/decreases all the way through the entire file duration?
Thank you

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
