Hi every body. I found JUCE last month and loved it very much.
I want to write a small program with JUCE.
It display PCM waveforms in realtime from multiple data source ( a multi-channel DAQ ).
I used multi-thread get PCM data,and make fft transform, at last draw the spectrums of difference data source on the difference component.
I did a 1024 FFT and displayed 512 magnitude samples every 200ms,I think it is not tme-consuming.
( My PC is Intel Core2 Duo E8400 3GHz ram 2GB )
But I found the speed of drawing was very slow,and the usage of cpu was high.
I didnt find content about graphic accelerate in the documents.I wondered whether there was some method to speed up the drawing performence.
Thanx for endure my pool english:)
