[PD] About internal delays
Hi, all My first post.. how exciting =) Well anyway...just one quick question. Does the audio buffer size that can be adjusted with -audiobuf flag stay constant all the time? Or is it something that PD adjusts dynamically in case of dropped frames or something? I been having some delay related problems and it seems that sometimes it changes quite randomly. The problem might also be with my hardware so now I'm just trying to find the source of the problem.

welcome to the pd-list! I am not sure, if many people still use the audiobuf flag, but I think it works... (another method would be to set the buffer in the audio settings.) and yes, it should stay stable during the whole time. what where the problems you had? because if the audio buffer is too low and Pd cannot handle the amount of data, the sound is shut down. usually a large buffer allows you to more complicated calculation (but increases latency). marius.

Re: [PD] About internal delays
Hmm... Okay. Then the problem should be in the hardware. I'm doing this kind of room impulse response estimation with nlms method and I get nice impulse response but if there is some cracks in the sound (from cpu load and dropped frames I assume) the impulse response shifts with random delay which shouldn't happen. I am using RME Fireface 800 audio interface in windows xp environment. Does anyone knwo if that might cause some problems?? -Mika Quoting marius schebella [EMAIL PROTECTED]: welcome to the pd-list!

On Fri, 23 Nov 2007, Patrice Colet wrote: Symmetric chords has as much tones as it has notes, diminished chords, has four fundamentals, also a minor seven chord might be relative with three major scales, and we have the choice between different chords with the same bunch of notes. eg: A C E G is both Am7, and C6 (C E G A), or Ok, but this is modulo octaves, so, there's no indication of actual frequency: 440*2=440 and 440/2=440 in that little world. And we were not really talking about the traditional music theory vision of a fundamental. I believe that we were using it to refer to a possibly hidden gcd (pgcd in French) frequency-wise, a highest common undertone, that can be applied to any combination of notes, so that for example, in ACEG it is à priori worthwhile to consider the highest common undertone of AC, AE, AG, CE, CG, EG, and then ACE, ACG, AEG, CEG, and then ACEG. Highest common undertone is quite similar to looking at ratios such as 3/2 for a fifth, 5/4 for a major third, ... except it relativises it with the actual pitch, because in practice a treble major chord is a lot more consonant than a bass major chord, for example. (i asked myself the question: why do bassists so seldom play chords?...) FM7 (F A C E G) or G13 (G B D F A C E)... Those two are only chords containing the original chord. They contain all of the same relationships, but they also contain additional relationships. Hardness of understanding increases when window size diminishes, like a blues we could play with only one scale with a little understanding, or all scales with applying knowledge of harmony all along the twelve bars structure. This is vaguely related to Heisenberg-style uncertainty: you have a limited number of hints in order to decode a melody, and if there are too few of them, you can't figure out. But Heisenberg's is only about waves. Originally it's only about wavicles (wavy particles at atomic level), it's been generalised to sampling of all waves, and I guess it could be faithfully generalised to some other transforms than Fourier's, but what I'm saying here about melodies is ultra-loosely-connected to Heisenberg. It's actually closer to reading or hearing words in a language and not knowing which language it is yet: if you read the word «information» it could be either French or English; if you hear the French word «information» it could also be Bokmål's «informasjon» and you wouldn't know unless you can really tell apart Bokmål's accent from all native French accents just by hearing that word. That said, meaning-wise for that word, it's pretty much all the same no matter the language. There are better examples. Within one language, there are homophones and homonyms. The homophones depend on the accent. In my accent and vocabulary, French «bosse», English «boss» and English «bus» all sound the same, and the latter two can occur in my French sentences. If I just say one word, the meaning can't be guessed further than finding a set of several possibilities. Melodies and scales are a lot more regular than the seemingly random associations of phonemes with meanings, but still, they have some of the discrete aspects that are somewhat oblivious to Heisenberg/Fourier. The only thing that is in common there, is what is called under-determination, and also what I'd call progressive determination: each note played can tell you a bit more about the scale in use and the way that the scale is being used and such, or about what could be a change of scales that has occured but has not been confirmed by the listener's interpretation yet (happens more in solo single-note than when extra notes give a much more immediate indication of what's going on). and also, a theory of musical understanding should be resistant to detuning, because many forms of detuning are used in music and yet humans can automatically figure out what the fundamental is _intended_ to be (rather than what it is physically). Dominant chords can contain all the notes that aren't into the fundamental chord, so we know by experience that the moment after this dissonant ambiance, No, we were thinking specifically about close detunings, all those intervals that are confused with a much simpler interval, and usually, which *should* be confused. It's the basis of logarithmic temperaments: 2^(7/12) is over 0.1% off from 3/2, and that's one of the best-matching intervals relative to just temperaments. So, my question is, how do we deal with that? When is a major third played like 2^(1/3) considered to be an approximation of 5/4, and when is it considered to be an approximation of 81/64 or some other? _ _ __ ___ _ _ _ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Building a compressor in PD?
hm.. don't quite know, how to answer this, i'd say yes and no. basically 'waveshaping' means adding non-linear distortions to a signal, a process, which enriches the frequency spectrum of the signal (- spectrum is altered). the goal of all dynamic processing fx as gates, compressors, limters, expanders is to only affect the dynamics of the signal, but not the spectrum. but yeah, they are somehow related: if you use very insane settings for a compressor, let's say 0ms for attack and decay, then you have actually a waveshaper. let's say you use very small values but not 0, then it is actually not exactly a waveshaper anymore, althouth the spectrum might still be altered. a waveshaper uses table look-up, so each input value has its corresponding output value, but a compressor with very short attack and decay is more kind of an 'adaptive waveshaper' (i am not that much an expert, so this term might not make any sense). however, what happens is more complex, because the current output value is not only dependent on the actual input value, but also on previous input values (and also if we are actually in 'attack' state or 'release' state). roman On Tue, 2007-11-27 at 18:50 -0600, Kyle Klipowicz wrote: I may be wrong, but might some of the waveshaping tutorials help with this?

You can hear this when applying a traditional compressor to low frequency sounds like electric bass and 808 kick drum where the wavelength of the signal is comparable with the compressor changes. Each cycle gets treated as if it were a separate event. Where compressor and waveshaper diverge is at Gabor period, 20ms (50Hz), it's no coincidence that where perception of frequency vanishes at the lower bound perception of amplitude picks up. let's say you use very small values but not 0, then it is actually not exactly a waveshaper anymore, althouth the spectrum might still be altered. a waveshaper uses table look-up, so each input value has its corresponding output value, but a compressor with very short attack and decay is more kind of an 'adaptive waveshaper' (i am not that much an expert, so this term might not make any sense). however, what happens is more complex, because the current output value is not only dependent on the actual input value, but also on previous input values (and also if we are actually in 'attack' state or 'release' state). I suppose, technically, you could say it has become a filter since the current instantaneous output depends on the average of previous input values. There are really two kinds of compressor. Feed forward compression places the averaging function parallel with the signal path and modifies the output gain. Look-ahead compression delays the signal path and calculates the gain reduction in anticipation. Each has its merits. The attack control on a traditional compressor actually does the opposite of what some people expect, it holds off the gain reduction to allow the initial transient through. That's desirable in mixing where you want to change the perception of loudness without needing a limiter since the apparent loudenss is a function of both amplitude and time - so you reduce the body of the sound while allowing the subtleties of the attack to come through and leave it clearly defined in the mix - good examples of use are for guitar, bass and drums. A feed forward method is superior here because we don't mess with the timing, which is what we want for percussive sounds. The other kind of use is averaging the overall level, as in vocal passages, in which case a look ahead compressor is better. Legato sounds like vocals and strings are less sensitive to being shifted a few milliseconds back but the levelling process benefits greatly from having a small amount of the signal to anticipate. a. -- Use the source ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] pdlua compiling on mac
hi (hans), I am trying to compile a recent version of pdlua on my mac. I know that last time I did this by putting lua.c into pd-extended and compile it from there, but I don't know anymore, how that is done. the makefile that comes with the tarball does not work for os x, and I also don't know how and what to include. what needs to be done to include this in pd-extended. is this possible at all, since it relies on a lua installation. or could that also be included in the pdlua package, since these files are not very big. thanks, marius. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I think that wouldn't be so good because then other loaders couldn't use the hex names. other loaders can't use the hex-names anyhow. what is currently in pd-vanilla is the hexloader _without_ the filename-mangling (only the setup-name is mangled) What's the hex loader do? as opposed to the hexloader in pd-vanilla, the hexloader-loader also mangles filenames. I am curious why you chose to make it a loader rather than to make it part of the core?
