An even faster AS3 FFT

Earlier today I posted code for a fairly fast pure-AS3 FFT implementation. Andre Michelle suggested that I could perhaps get better performance by using linked lists instead of Vectors.  He was right!  I have a new FFT implementation that runs … Continue reading

An FFT in AS3

I write a lot of audio signal processing code, a fair bit of which works in the frequency domain. A key building block for almost any frequency domain signal processing is the FFT, an efficient implementation of the DFT. A … Continue reading
