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.
