Hi All

I have downloaded Bob Larkins latest F32 open - audio lib. I'm trying to produce a basic audio spectrum for my my project. I'm using a T4.1 - AudioControlSGTL5000 and ILI9341 display.
My AudioSettings_F32 audio_settings(sample_rate_Hz, audio_block_samples); sample_rate_Hz = 48000.0f; audio_block_samples = 32;. There is a AudioAnalyzeFFT1024_F32 example
but I'm struggling to understand or how to produce a basic audio spectrum/ waterfall to display half or all the spectrum. Any advice/Idea's how to do this would be greatly appreciated.

Thanks in Advance
