@cfry Those sorts of sounds can be gotten as well and a more sensitive mic will pick them up. The problem you are having is the mic is just getting noise, everything of the same volume, so nothing distinct for [sigmund~] to pick out, remember all those discrete sources add together. By wind noise I meant the sound of wind hitting a microphone directly, this creates a constant sound which will over power all those other sounds, not the sound of wind rustling the leaves in a tree. A good wind screen will be very helpful for you here, but you need to remember, a windscreen does reduce mic sensitivity, so there is a trade off, increase mic sensitivity and the more wind noise it picks up, put on a denser wind screen and you loose some of that sensitivity. A pop screen could work better since it can be placed between the wind and the mic, the other sides of the mic are left open, but if the wind shifts you could end up with wind noise overpowering everything and have to reposition the screen. If you limit yourself to days with nothing more than light winds, you should be able to get by with just a light windscreen and not suffer much loss in sensitivity.

My knowledge of windscreens and pop screens and the like is fairly limited and largely theoretical, I have little hands on use of these things as I mostly record in more controlled environments or in situations where I have more leeway than your needs allow. Seeking out people or sites dedicated to making field recordings would likely be your best path on finding a good mic/pre setup for your needs.

.... now the parentheses come into play: Instead of actually using the given coordinates x0 and y0, Pd arranges each point relative to the value range given in parenthesis:

The first x0 can move between 0 and 240 on the x axis and between 0 and 240 on the y axis. The second x0 can move between 0 and 240 on the x axis and is therefor placed at the same height as the first one.

But the second one can be moved between 10 and 250 on the y axis and is therefor placed below the first one (counting from top on the y axis, if i recall correctly).
.....

hey again! i'm still having problems to understand, how these boundaris exactly work. let's have a look at your example:

the first pair of coordinates seem clear so far. the second pair describes the point below the first one, if i got you correctly. so the x0 variable can move between 0-240 on x-axis and 10-250 on y axis, which is 10 point below the first one.
BUT... why do the boundaries of the y0-variable differ from those of x0? they do describe the same vector, so i presumed, the'd also need to be bound to (0:240)(10:250). the next coordinate pairs are equally obscure to me.... let's look at the third pair, which i guess, is the point to th right from the second one. why is x0 bound between 0 an 240 on the x-axis? shouldn't it be bound to (10:250), as it should have a 10 pixel offset to the other points? sorry for my silly questions, but this is really confusing to me...

I just see this flag on linux:
-nosleep -- spin, don't sleep (may lower latency on multi-CPUs)

Oh yes and there are startup flags for loading a different scheduler (I corrected this in my first post now)
https://puredata.info/docs/faq/commandline

  -rt or -realtime -- use real-time priority
  -nrt             -- don't use real-time priority
  -sleep           -- sleep when idle, don't spin (true by default)
  -nosleep         -- spin, don't sleep (may lower latency on multi-CPUs)
  -schedlib <file> -- plug in external scheduler
  -extraflags <s>  -- string argument to send schedlib
  -batch           -- run off-line as a batch process
  -nobatch         -- run interactively (true by default) 

Not sure, would be interested to know too.

i am not sure if it is the best solution, but it works now (with setFromPixels) it is a variable framebuffer and the example buffers the last 300 frames from a video.

@Cuinjune I tried to create a video frame table ("circular video buffer").
It is possible to read (draw) video from the table but somehow only the current frame is stored at every position of the table.
Here is an example patch. "frames" is the frame table. "N" is the table size. At the left is the texture from the table, at the right the original video. Do you know what I do wrong?
I also tried ofPixels instead of ofTexture with the same result.
And I tried to store several images (jpg´s) instead of video to the frame buffer, which does probably work because each image has its own source.

i think it is possible after trying a bit.
what seems important:
-use photo JPG (or something similar) as the codec for the video. a good program for converting is http://www.squared5.com/
-use setPosition and not setFrame for scrubbing or playing reverse through the video (it is much faster)
-playing with setPosition is without sound
-for playing with setPosition the video needs to be paused
it is adapted from the video example and can be optimized a lot to work like the [pixfilm] object...

Fifth Annual Web Audio Conference - 2nd Call for Submissions

https://www.ntnu.edu/wac2019

The fifth Web Audio Conference (WAC) will be held 4-6 December, 2019 at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. WAC is an international conference dedicated to web audio technologies and applications. The conference addresses academic research, artistic research, development, design, evaluation and standards concerned with emerging audio-related web technologies such as Web Audio API, Web RTC, WebSockets and Javascript. The conference welcomes web developers, music technologists, computer musicians, application designers, industry engineers, R&D scientists, academic researchers, artists, students and people interested in the fields of web development, music technology, computer music, audio applications and web standards. The previous Web Audio Conferences were held in 2015 at IRCAM and Mozilla in Paris, in 2016 at Georgia Tech in Atlanta, in 2017 at the Centre for Digital Music, Queen Mary University of London in London, and in 2018 at TU Berlin in Berlin.

The internet has become much more than a simple storage and delivery network for audio files, as modern web browsers on desktop and mobile devices bring new user experiences and interaction opportunities. New and emerging web technologies and standards now allow applications to create and manipulate sound in real-time at near-native speeds, enabling the creation of a new generation of web-based applications that mimic the capabilities of desktop software while leveraging unique opportunities afforded by the web in areas such as social collaboration, user experience, cloud computing, and portability. The Web Audio Conference focuses on innovative work by artists, researchers, students, and engineers in industry and academia, highlighting new standards, tools, APIs, and practices as well as innovative web audio applications for musical performance, education, research, collaboration, and production, with an emphasis on bringing more diversity into audio.

Keynote Speakers

We are pleased to announce our two keynote speakers: Rebekah Wilson (independent researcher, technologist, composer, co-founder and technology director for Chicago’s Source Elements) and Norbert Schnell (professor of Music Design at the Digital Media Faculty at the Furtwangen University).
More info available at: https://www.ntnu.edu/wac2019/keynotes

Theme and Topics

The theme for the fifth edition of the Web Audio Conference is Diversity in Web Audio. We particularly encourage submissions focusing on inclusive computing, cultural computing, postcolonial computing, and collaborative and participatory interfaces across the web in the context of generation, production, distribution, consumption and delivery of audio material that especially promote diversity and inclusion.

Still using pd extended 0.43 here on windows 10 in combination with and rme fireface using the asio drivers. However, since a couple of days the asio drivers (in pd) went missing. When opening the audio settings, normally in the input/output devices I can select the rme asio, but now it's just 2 empty dropdown-buttons.

Anyone any idea where pd looks to fill up these lists and how I could get my rme asio drivers back?

Regards,

Domien

@matthieu1978 Hello......... too late!
@moscardo...........
I use the same device. You will need ASIO. I do not remember why, but I ended up using Asio4All as the driver. I think I had some problems with the Motu drivers but.........?

Asio4All lets you make the Windows equivalent of an "Aggregate Device"...... so as many sound cards as you can connect....... !...

Asio4All ..... http://tippach.business.t-online.de/asio4all/

Before you start open the Motu Audio settings and set the samplerate, 64 samples per buffer, Internal master clock, tick "Use stereo pairs for windows audio".
In the second window make sure everything is ticked that you might want to use.

Select ASIO in Pd.
Select Asio4All in the Audio settings window.
Tick to use the ins and the outs......

When you have selected Asio4All in Pd then set......
the samplerate you want (must match the setting in the MOTU Audio Console settings
Delay (msec) 2 or 3 should work.
Blocksize 64
Tick the "callback" box
Set 32 in channels (set more if you want to use the built in computer soundcard at the same time)
Set 30 out channels (if more channels... as above)

You can now look at the Asio4All setup. A little green arrow icon should have appeared in the bottom right of windows.
Open it, click the "Spanner" and set like this for all the analog channels.
Highlight (click) the boxes at the left side for digital ins and outs and the inserts and reverb returns if you want to use them them.

Even if the inputs (or outputs) are not in the correct order, they will stay the same, even after re-plugging the soundcard, rebooting the computer, and re-starting Pd.
