[PD] beginner's question - the audio doesn't work
Hello, I am not a sound professional and I have only been using PD for a short while so excuse me if it's a stupid question. I am trying to create a short ringtone-like melody using PD. I created a patch that reads data from an array and then connects to dac~ but when I try to turn the toggle on no sound is coming out! How can I change so I could actually hear the sound? I have attached the patch with this message. Thanks a lot! assignment2.pd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] PD, Linux and USB multichannel interface
Most of USB audio devices out there are basic stereo in // stereo out and they can do up to 48kHz sampling rate. What you need is USB audio 2.0, which is firly recent, despite the fact that most of other USB devices use the capabilities of 2.0 standard, the audio products didn't catch up just yet. There very few implementation out there, if you find any thing decent - let every one know! I haven't looked it up very recently, so there may be something already :) The latest ALSA driver should have quite good support for it, I would advise you to browse ALSA dveloper's mailing list. for example I can see from back in August: [alsa-devel] Problem with USB Class 2 Audio Driver Good Luck, -- Ilya On Thu, Nov 18, 2010 at 09:42:51PM +0100, Carlo Benzi wrote: Hi!

The outgoing frequencies from mtof are between 8 and 10hz, so this maybe the reason that you can't hear anything. Try modifiy /increase the values of the array or multiply the values from the mtof outlet.

We also encourage you to take an active part, and put up suggestions for topics you want to talk about / topics you want to be talked about. Doors are open from 20h-20h15. After that they'll be closed, and you will have to call someone from the Pd-meeting to get in. To get a telephone number to call or confirm assistance you can write to jmmmpais _ at _ googlemail.com. Please, don´t call to the staff of NK to open the doors. They let us use the space but we have to take care about having the meeting without producing any disturbance to them, and to clean the space after the meeting. We would apreciate if you would send us a small mail to info_at_minitronics.net with your name, Pd experience and interests, so that we know how many people might be coming. Or put your name in the pd-berlin wiki page. We would like to thank the support and willingness of NK in the organization of these events.

Then can you explain what's wrong in my reasoning ? (the formulas I wrote) no, sorry, I can't on the quick. but I know for sure that frequency modulation only produces harmonics if the carrier and modulator are in simple relations like 1:5 or your example 200 to 1000. The frequencies added by fm are multiples of the modulator added and subtracted from the carrier. (carrier; 1000Hz, modulator 11Hz -- pairs in order of strength: 989 + 1011, 978 + 1022 Hz ...) If you have frequencies going below 0Hz they wrap around the y=0Hz axis. Result is a negative freuqency, or likewise the phase is reversed. (for example 1000Hz modulated by 600Hz will have 200Hz in the spectrum) If you use not-harmonic related frequencies like 320 and 1000 Hz and you will have new frequencies which aren't multiples of 320 and 1000, but inbetween. (580 and 1320, ...), Also you will get frequencies below the 320 Hz. However if you drive the modulation very strong, a patten similar to a harmonic signal will appear, possibly with a new base frequency, but also likely without. I'm absolutely not familiar with the case of a signal modulating itself, but I'm pretty sure from experiments with your patch (or the new I mad and attached) that there occur very similar (if not identical) effects if you modulate a mix of 1000 + 320 Hz with itself or you use separate carriers for 1000 and 320 Hz and modulate them separately by the mix of 1000 + 320. I'm not sure if this superposition is valid, but I'm pretty sure... at least it sounds relatively similar if I do it in pd. The vd~ sounds always richer possibly artifacts. (the spectrum looks very dirty too) I want to add that the vd~ approach is not the perfect implementation for the above described frequency modulatuon. the carrier is delayed against the modulating signal a bit. You can add another [vd~] or [delread~] to fix that. I think I did that in some other version of haut-parleur-doppler.pd, and if not, I did similar things with other effects. Like this it simulates a moving listener instead a moving sound source. But there is no difference between a moving listener and a moving source, apart from the wind. there is. but for the low speeds of the cone we are simulating the audible effects are not very different. (a moving sound source at the speed of sound produces infinite frequency, a moving listener at speed of sound hears only doubled frequency). What you mean is, regardless of whether it happens in the listener or the source, the motion is out of phase with the actual signal. exactly and this is why I'd like to move the write head. How did your correction using vd~ work? Unfortunately I don't know of such externals already existing. However I don't expect the effects being very different from the vd~ method. What if they aren't _any_ different ? it's only because of the slight delay I'd be interested to eliminate. But as you also said I don't expect any big difference between the delay free case and the vd~ case as the modulations occuring with a slight off phase will not sound any different. (however 2ms can be quite different for short percussive signals) A slow 20Hz sinewave modulating some high frequencies will not sound very different if the 20Hz is delayed or not. A 20 hz sound will have a duration which is much longer that the delay. But it depends on the gain you choose. Suppose you have a weapons-grade giant speaker, with a membrane of a few hectares... I mean, play with the [*~] and you can get the delay variation to be bigger than the period of a sinewave. yep, that's also one of the effects I wanted to eliminate by the moving write head.

I think that my reasoning is mostly correct and that our difference is that while I'm insisting that periodic signals remain periodic, you are insisting that nonperiodic signals remain nonperiodic, or something like that. If you use not-harmonic related frequencies like 320 and 1000 Hz gcd(320,1000)=40. 320 is the 8th harmonic of 40 Hz, while 1000 is the 25th harmonic of 40 Hz. will have new frequencies which aren't multiples of 320 and 1000, but inbetween.

The vd~ sounds always richer possibly artifacts. (the spectrum looks very dirty too) Probably due to the use of Lagrange interpolation instead of something suitable for splines, such as Natural Spline interpolation. I still want to make my own version of vd~ using the latter... not now. But there is no difference between a moving listener and a moving source I was wrong. IIRC, that statement is only true for light, not sound. (?) (a moving sound source at the speed of sound produces infinite frequency, a moving listener at speed of sound hears only doubled frequency). Why are you not taking the direction of the motion into account ? If you go at speed v towards a static sound source, you hear everything at speed 1+v/c, whereas if you move away from it, you hear everything at speed 1-v/c. exactly and this is why I'd like to move the write head. How did your correction using vd~ work? The correction I made just uses a [delread~]. For example if you have [+~ 1]-[*~ 5]-[+~ 2], you need a [delread~ a 7], because 1*5+2 = 7. it's only because of the slight delay I'd be interested to eliminate. But as you also said I don't expect any big difference between the delay free case and the vd~ case as the modulations occuring with a slight off phase will not sound any different. (however 2ms can be quite different for short percussive signals) Well, it does sound different in some way, but the changes I get by changing that delay, are less special than what I get by making that effect happen in the first place, instead of not. It makes me think of other delay tricks such as comb filters. yep, that's also one of the effects I wanted to eliminate by the moving write head. If you make a moving write head thing, though, it needs to be additive, and the energy has to get stretched like the derivative of the motion (the speed of the head). The data may have to be spread into a not-very-bounded amount of array elements. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
