winmm + audio level for VU meter

[nico_van_wijk]

Dear people,

Is it possible to use Winmm.dll to display the audio level with a VU meter. I use winmm to play a wav-file and display a VU meter.

Thanks

Nobody?

I've tried something with mciSendString("status recFile level", s, 255, 0), but nothing returns. I think my soundcard doesn't understand this mciSendString?

I think nobody knows a solution, so I think it's better I don't use Winmm.dll. Maybe the bass.dll is something for me.

Why don't you use DirectXSound ?

Here's my sound tutorial (not finished) if you don't know how to use DirectSound:

It depends on your soundcard. If your soundcard has a peak level meter then you can use the multi media api's:

If not you have to check the samples yourself via DirectXSound or the wave-in api's

I've been searching for some samples for long time. It should be great when I can use the waveout api to play en show a Vu-meter.

I think this is a very complex problem, because a lot of people have the same problem. Is there then nobody who have some sample code?

Did you look at my tutorial ?

Here's another example:

Your tutorial is excellent, I have learned so much about Directsound. One thing though, is there any way of splitting the two channels to different sound files, at the saem time or seperateley.
I think it may be a tall order.

Hi UKnod,

There is section in my tutorial "Splitting a Stereo buffer to 2 Mono buffers" (second last post).

All you have to do after that is to save the files...
