Sound Input Device error -2147024891

1. Please activate unter Windows Settings/Privacy/Microfone the Lexis Audio Editor.
2. Under Windows x86 at least one audio input driver should be installed.
To verify this open in the Windows Control Panel “Sound” and there choose the tab “Record”.

How is the lowest possible bitrate?

The minimal bitrate in Lexis Audio Editor is 96kb/s. If your record is in a lower bitrate LAE saves it anyway in this quality.

Is there any way to record solely from an active internet audio stream directly via the soundcard (without getting external room sounds from the MIC-IN)?

Under Windows 10 desktop and tablet:
Open in the Windows Control Panel “Sound” and there choose the tab “Record”. If there is no item “Stereomix” click right and choose “Show deactivated devices”.
If the item “Stereomix” is visible aktivate it (Right click).
Set the Stereomix as statndard with a right click.
In some cases the installed audio driver has no Stereomix. You can search the original driver from your Sound card vendor.
Another solution is a software „Virtual Audio Cable“.
