Hi, After gprof'ing Lame 3.92, and looking at the source, I think fht.c might be an ideal candidate for vectorising with OSX's Altivec optimised DSP library.
Could somebody please confirm the following (regarding fft.c) : (1) Function arguments static void fht(FLOAT *fz, int n) *fz = ptr to time-domain data (in what order ?) n = the size of the input data to transform e.g. n-point dft (what is the valid range for n ?) (2) the function is in-place (that is, the input data is over-written by the output data) Thanks in advance. Much appreciated.
