[pd] 100000hz+
i just made a synth which makes some really nice tones when i feed it really high frequencies. (midi notes 150-300) question is, will this sound the same on all computers, or do different systems handle such high frequencies differently? ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hallo! i just made a synth which makes some really nice tones when i feed it really high frequencies. (midi notes 150-300) question is, will this sound the same on all computers, or do different systems handle such high frequencies differently? Hm ... it depends in the sampling frequency. The frequencies are mirrowed at sr/2, so if the sr is the same it should work (but I haven't tried it ...)

Re: [PD] Firewire interfaces and PD?
Hmmm... I'm interested on the Firepod, but I am I little afraid about processing issues... It seens to be a nice soundcard since it has 8 preamped mic ins, what could be very useful on interactive performances... no mixer or preamps needed at all. Do you know anything about it? About Motu... It seens a very good interface but not yet ready to work in linux.. Freebob team is working on firewire interfaces but the companies are not realy helpful on giving support... It is stupid, because I would spend a little more money to buy a Motu device if it had linux support. It seens that it will work on the next Freebob release... And what about the Edirol interfaces? Any experiences? Thanks for the answers... alexandre r. decoupigny escreveu: yep. i use the presonus firebox and OS X 10.4.1 with PD. it works absolutely well with both audio and midi. it only takes more processing power, so patches run a little slower than compared to the built-in sound. I think this is worth it, since i also use it for multispeaker purposes and NEVER the two (Pd and the Firebox) did they have trouble communicating. seems the two like each other. Once my old Firebox became unreliable so i contacted the German distributer and the store i bought it from and within two days i had a new one. Only downside is that i had to pay to send it pack. I really like the Firebox. It was recommended to me by Kim Cascone, who has some years of experience and he was absolutely right about this sweet little box : ) best alexandre On 25/10/06, *padovani* [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: I would like to know if anyone is using one of these interfaces (on WinXP/ OSX/ Linux-freebob) for interactive performance with PD.

Don't be too bummed out. Given what's been said here I'm not sure exactly how this happened, but I made the types of sounds you're talking about (an [osc~] at +127 midi) and recorded them to a wav file and imported that wav file into a .XM file and then played that .XM file back on a gameboy advance, and it sounded pretty much how it did in the original instance, despite the fact that it was playing back at a different sampling rate and underwent conversions between different sample rates in the process. If I was you I would experiment with your sound on some different systems before giving up. I guess sometimes practice confounds theory.

Re: [PD] Re: multi-speaker panning.. problamtic maths
I made this mistake again last thursday - I computed sound amplitude of some kind of omnidirectional source as being r^-2 where r is the distance. However, I believe that it's energy that should be r^-2, therefore amplitude should be r^-1. That's assuming ideal 3-D dispersion (no ceilings and no walls). Is that right? Exactly right. For that ideal environment, we have the intensity (W/m^2) distributed evenly on the surface of a sphere at radius r. So, since the surface area of the sphere varies as r^2, the intensity falls off at a rate of r^-2. The energy of the wave is (mostly) conserved, it just gets spread out over a larger area.

If you render the output to a .wav file it is captured as a snapshot and the sample rate no longer has any effect (other than to change the overall playback rate). The problem others were trying to explain is that the synthesis patch is not independent of sample rate, so using the same Pd patch at different sample rates will produce different results. If you're recording it the problem doesn't exist. I am not sure if I understand this distinction correctly. If I use Pd at 44100Hz to generate a high frequency wave that aliases, and save it as a 44100Hz wave file, shouldn't that wave file be subjected to different aliasing if I play it back at say 22050Hz? What about if I upsample it to 96kHz? Will the aliasing weirdness disappear if the tone I played was below 96kHz? Or is it somehow baked into the wav file. I think I am out of my depth here.
