Dan Stowell: Removed strange "zeroing" part of xtract_mfcc() which was zeroing a load of elements despite the fact that they're ignored by the DCT process called next, and never used for anything. This was writing to an assumed large result array (same size as number of FFT bins) despite the fact that only a small number of MFCCs (typically less than 50) are required, therefore either wasting memory or writing to memory it shouldn't do!

Add -fPIC in intelligent way to build system for 64-bit builds Rationalise use of powf etc. vs pow Add spectral_flux Add geometric_mean Add spectral_mean, spectral_deviation, spectral_geometric_mean etc. Add weighted temporal features as per Peeters (xtract_weighted_mean etc) weight given as argv? Improve noise robustness of xtract_f0 Fix xtract_hps - it doesn't work! Add Pure Data help file Add delta functions Add Max/MSP external example Check and add return values as appropriate. Make them more sensible! ...do other stuff and eventually... ...optimise!
