Hey Patrick,

So, I've probably screwed up some stuff here with GSL, but I've been learning a hell of a lot with regards to vector operations, and porting the vDSP accelerate stuff to GSL. Eventually I suppose it would be good to get rid of that, and only use standard libs, except where the FFT stuff is concerned when we'll use either d_fft_fftdg.c or d_fft_fftw.c from pd src.

Also, I was reading an article about dereferencing, and I think I might have used &x-> where just x-> is needed for gsl_vector_float operations, and I know the initialization functions gsl_vector_float_calloc() are wrong sized - I need to work out which need to be MAX_ORDER and which to be sized and initialized at size = nfft or size = nfft02 (It's 10pm and I'm also trying to master an album!)

Well, it's messy right now. Don't bust a gut on working all of it out, but if you can speed me up by spotting a few things it'd be appreciated.

I feel like I've absorbed a couple of megabytes in my head since the weekend.

Cheers,

Enclosed - the original Max code and my incomplete hash of it - but I'm trying to port the hardest bit I think...

Things will be renamed before a release to acknowledge Mark Cartwright, (as in mbc.lpc~ for the original MSP extern) but I haven't decided on the namespace options yet.

I know you eagerly anticipate this! I have a lot of work to do...

you are my hero. what will they do exactly? lcp encoding, decoding? lcp-streams to audio?

Hi List,

I'm porting a library of LPC externals from Max/MSP to Pd.

I wonder if someone could point me towards an example of another MSP external that has successfully been ported to Pd - preferably a DSP external that has creation arguments, with code for both so I can identify the differences between coding for the two platforms.

Cheers,
Ed
