Re: [PD] better tabread4~
On Mon, Jun 23, 2008 at 8:23 AM, cyrille henry [EMAIL PROTECTED] wrote: well, tabread4c~ is far from perfect, it has the same aliasing problem than tabread4~ and it create more distortion than tabread4~. (but in lower frequency). Strictly speaking, these interpolations don't create distortion in as much as they have a non-flat frequency response. No matter which method you use, the interpolation function can be re-written as a convolution, which is linear. In my prior analysis of the tabread4~ impulse response, I obtained the following function for the impulse response. g(t)=I[-2,2](t)(-1/6*|t|^3 - 2*t^2 - 11/6*|t| + 1) + I[-1,1](t)(2/3*|t|^3 - 2*t^2 + 4/3*|t|) And it's fourier transform, where w=pi represents the Nyquist frequency. (by the way, the angular frequency notation greatly simplifies the calculus involved) G(w)=(1/w^2)*[1/3*cos(2w) - 4/3*cos(w) + 1]+ (1/w^4)*[2*cos(2w) - 8*cos(w) + 6] This function falls off at a rate of at most -6 dB/octave (according to the 1/w^2 term). What you are referring to as distortion is not actually distortion, but aliasing and a non-flat frequency response. The spectrum of this function is pretty nice, but everything above pi rad/sec is aliased, which causes some additional frequencies, mostly high frequencies. I'm reluctant to do the same for tabread4c~ because it takes several hours to do. If you come up with a good set of coefficients that seem to be pretty solid, I'll spare some time for the frequency response. one told me that modern commercial audio software can use 32 points shannon interpolation. http://en.wikipedia.org/wiki/Whittaker–Shannon_interpolation_formula i'd like to try that... it will be more expensive, but this is negligible on recent hardware, and sound quality worth it. I doubt that it would be negligible. I do agree that it would find many applications, but not as a replacement for a fast, good-enough tabread. 32-point windowed sinc interpolation borders on anal retentive. Instead of that, it might be better to probe out what degree of fast polynomial interpolation will have a good-enough spectrum.

Re: [PD] better tabread4~
Hello, The speed of this conversation makes me a little uncomfortable. Perhaps [tabread4~] is not so weird after all: if I'm not mistaken, this is algebraically identical to the interpolation used in csound's opcodes (e.g. oscil3)... I'm pretty sure both are piecewise Lagrange polynomial interpolators (with x_i values equal to -1, 0, 1, and 2, and interpolation between x=0 and x=1). There seems to be, then, at least some consensus about what generic cubic interpolation means, given csound's rather long history to sort this out (though, I'm surprised they haven't pulled together some of the algebra to reduce the number of divides... maybe this leads to a more accurate result?). I would be a lot more comfortable if it could be established exactly what kind of cubic interpolation is in the [tabread4c~] -- this would help with the naming standards as well. Whatever new algorithms become available should be extended to the vd~ class (or copies thereof) as well. BTW, the naming difference between csound's oscil3 and [tabread4~] (one has 3 and the other 4) seems justified, since csound will automatically calculate the two extra guard points you need (tables in csound can come with one guard point, but not more, so the 3 is a clear reminder that it's doing cubic interpolation), and in PD, the guard points should be put in the table by hand (so the 4 is a reminder that it's always using 4 points). This is one important reason [tabread_transpose~] and the like should not be implemented, unless the guard points are automatically generated in the object class. For the value of the consumer I appended the relevant code snippets... Pd code, from d_array.c: a = wp[-1].w_float; b = wp[0].w_float; c = wp[1].w_float; d = wp[2].w_float; cminusb = c-b; *out++ = b + frac * ( cminusb - 0.167f * (1.-frac) * ( (d - a - 3.0f * cminusb) * frac + (d + 2.0f*a - 3.0f*b) ) ); csound code, from OOps/ugens2.c: MYFLT frsq = fract*fract; MYFLT frcu = frsq*ym1; MYFLT t1 = y2 + y0+y0+y0; ar[n] = amp * (y0 + FL(0.5)*frcu + fract*(y1 - frcu/FL(6.0) - t1/FL(6.0) - ym1/FL(3.0)) + frsq*fract*(t1/FL(6.0) - FL(0.5)*y1) + frsq*(FL(0.5)* y1 - y0)); Date: Mon, 23 Jun 2008 14:17:36 +0200 From: Roman Haefeli [EMAIL PROTECTED] Subject: Re: [PD] better tabread4~ To: pd-list@iem.at Message-ID: [EMAIL PROTECTED] Content-Type: text/plain On Mon, 2008-06-23 at 06:52 +0100, Andy Farnell wrote: Yes that'right, hmm I guess I knew that but said it in a woolly way Amend that to [tabread~] - play back at exactly the original rate [tabread4~] - play back at close to the orginal rate [tabread4c~] - play back with wider transposition i don't see any justification to keep [tabread4~] in this list. cyrille once mentioned that his new class isn't computationally more expensive. if there is a difference between [tabread4~] and [tabread4c~], then it is, that [tabread4c~] is _better_ than [tabread4~] (according to some previous posts regarding this subject). the only good reason to keep [tabread4~] in pd is to keep backwards compatibility with patches that exploit [tabread4~]'s wierd behaviour, imo. roman ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
