can't compile Audio_Input _with_Knob_Filer example.

[DeviceUnderTest]

Hey All,

I have just installed the Mozzi library on both a windows and Linux machine and seem to be having issues compiling the Audio_Input _with_Knob_Filer example.

I get:

-'getAudioInput' was not declared in this scope

Audio_Input_with_Knob_Filter.ino: In function 'int updateAudio()':

Audio_Input_with_Knob_Filter:48: error: 'getAudioInput' was not declared in this scope

Anyone seen this issue?

HI,

Have you edited mozzi_config.h where it says:

    #define USE_AUDIO_INPUT false

and changed it to:

     #define USE_AUDIO_INPUT true

as suggested in the notes at the top of the sketch?

Works for me...

Don't I feel dumb.

Thanks so much.

I see in the header there is a typo:

/** @ingroup core

Whether or not to use audio input.

Put \#define USE_AUDIO_INPUT false in Mozzi/mozzi_config.h to enable audio input on analog pin AUDIO_INPUT_PIN,

otherwise make it false, to save resources.  When audio input is used, don't read 

other analog channels as they'll interfere with the audio sampling.

*/

Think that should say true.

Thanks again

Aha!  Thanks to you too!  It will be nice in the next release to have the docs not say the opposite of what they should!  Also, that line about not using other analog channels has to go - the sketch shows how to do it with mozziAnalogRead().

Cheers DuT
