Re: [Laszlo-user] Setting Microphone Properties

[Michaela Merz]

Hi Max:

doesn't work. No mic.level info if 'capturing=false'. I happen to notice
that I won't get any mic.level information if codec has been changed via

<method name="_makeDevice"><![CDATA[
   var dev = super._makeDevice();
   dev.codec = 'Speex';
   dev.soundTransform = this._sound;
   dev.setUseEchoSuppression(true);
   ]]>
</method>

with or without 'capturing=true'.

So: On my whishlist would be:

mic.SetGain()
mic.SetCodec()

and, of course some mic.level info even if capture is set to 'false'.

Thanks for all help and happy, well, whatever it is you all celebrate :D

mm.
