Hi SuperGod,

We've failed to reproduce the problem you reported.

Could you let us know your Format settings?
(If you choose "44100 Hz" at the Frequency menu, you will see 44.1KHz.)

[SuperGod]

ANY codec, ANY settings, just AVI container.

Setting MPEG-1 L2 44 100 in badicam produce video file with 48 000 audio
32 000, 24 000, 22050 works fine.

I even tried on a complete FRESH machine, the same result, the latest version.

MP4 container works fine, but it is AAC so I'm not suprised, it's not broken.

MediaInfo can't be wrong, I even extracted audio, yes, it is 48 000 instead 44 100.

So the problem seems to be that the AVI files can only be saved sampling rates 24kHz, 32kHz and 48kHz.
(I tested it out myself)

My only guess is, that the AVI container simply doesn't support custom frequencies or that there's a bug in Banidcam.

I hope I was able to help,

Of course it is a bug, simple as that.

With that argumentation you would be unable to have an avi file with a frequency of 24kHz, but you can, even with the MPEG-1 audio codec.

[SuperGod]

Sampling rates: 32, 44.1 and 48 kHz are part of basic MPEG-1 Audio Layer II
It's pretty obvious they implemented the other formats like 22K

But whatever, forget about what wiki says.

We've failed to reproduce the problem you reported.

That means it works for them so it is supported.

44 100 can be set, it's there, inside a program so it should work.
If not, it's buggy.

I'm more concern about having them a problem to reproduce this since me and my friends got the same results.
Pretty weird.

Hi SuperGod,

We misunderstood your first post.

We could reproduce the issue you reported and have forwarded this issue to the development team.

Thank you very much for your report.

[SuperGod]

Thank you.
