New analyser module with FloatingTile support

[Christoph Hart]

Hi everybody,

I've added a audio analyser module that contains an oscilloscope, a FFT analyser and a goniometer (stereo-field analyser). While the actual module is pretty basic, the most interesting feature is that you can add these to a FloatingTile (with customised colours) on your plugin interface:

I'm getting a few build errors

I'm wondering if I need to update my version of IPP... also are IPP compatible with GPL?

Edit: Updating IPP didn't help.

[Christoph Hart]

Ah shoot I forgot you need IPP for this. I‘ll add a fallback solution (the fft performance is not super critical here).

[d.healey]

Aha I realised that although I'd installed IPP I'd forgot to set it up in JUCE.

I found this post on the JUCE forum very helpful - https://forum.juce.com/t/intel-ipp-free-community-licence/16677/26

These are the linker flags that I required on Linux Mint

/opt/intel/ipp/lib/intel64/libippi.a 
/opt/intel/ipp/lib/intel64/libipps.a
/opt/intel/ipp/lib/intel64/libippvm.a
/opt/intel/ipp/lib/intel64/libippcore.a

This new module looks like a lot of fun, I don't have an immediate use for it but it's nice to play around with.

[Christoph Hart]

Fixed now. There's no fallback yet (just deactivates the FFT Analyser), but at least it compiles.
