hi there!
i would like to know if there is any possibility to improve encoding speed by combining the 2 transfomations (MDCT + FFT) by exchanging the psychoacoustic model transformation (FFT) with an MDCT and then reducing the two MDCTs to one. is there already an implementation? and where can i find more information concerning this topic?
This should be possible as some AAC encoders are working this way (Psytel and Nero).
However, the fft transform is not that slow compared to the overall speed (at least in Lame)
