It probably is possible, but as bigger text manipulations IMO are better dealt with outside of the Pd language, why not learn Lua now and use the pdlua external to write your own powerful text manipulation objectsr? Or Python, but pdlua is much easier to install. hmm, the problem is that

thanks. I did it for now using splitfilename, s2l and unpack. Here's a way using zexy/s2l and l2s (see attached). Or you could use some of the objects from jasch_lib + cyclone/fromsymbol. -Jonathan --- On Mon, 11/1/10, João Pais jmmmp...@googlemail.com wrote: From: João Pais

[PD] soundifle_info bug with big files?

2010-11-02 Thread João Pais
Hi, I'm trying out soundfile_info, and with a file with 2,7Gb (~3h, 44100Hz, 24b), I get a sample count of -7. Probably a bug, is this the exponential of the number? With other files up to 1,8Gb it works well, though. Pd-ext 0.42-5, XP. (I can try later in ubuntu, if I get the chance)

I've attached my best attempt at recreating this effect, the attached PNG will be used as a reference. Given the distance d1 and d2, these distances are usually identical in a traditional bitcrush or simple quantization. I would like to be able to vary the distance between points of an incoming

This is even better. If I could minimize the jumps around Y = 0.5 to -0.5 It'll be exactly what I'm looking for... or a start at least. Do you see what I mean now? See how the amount of quantization changes with Y and a minimum quantization value? I think I'm getting towards the answer now...

So you want amplitude 'a' dependant quantization size 'q' ? take your chosen q(a); in your example it seems you want a simple line: q=q(0)-k*a; define f(a) as integral of 1/q from a=0 to a; also calculate the inverse of f(a) i.e. a(f); now for each sample do: out=a(round(f(in))) where round is

The reason you use the inverse is so that the amplitude remains the same albeit quantized. The reason we use another function before flooring is to distritube the floor levels.But afterwards we need to bring the values back to their original place On 2 November 2010 19:37, Ludwig Maes

I don't remember whether I posted this before. It's an external that doesn't define any classes, but installs a crash report handler that prints to the terminal. It requires execinfo.h which is linux-specific. It decodes C++ symbols using cxxabi.h (provided by glibc). This means you don't
