    Thanks. I was just looking at the examples to try and understand them, assuming they would still work. I'm guessing that some change was made to Pd since they were posted here 5 years ago that caused some things to break. One of the risks of relying on undocumented features, of course. There's nothing in particular I want to do at the moment, except to get a better understanding of how dynamic patching works.

    Do the examples in the zip file from 5 years ago still work in the latest version of Pd? I'm getting the errors below when I try '5.examples/2.create_new_abstract.pd'. I'm running Pd v0.52.2 under Windows 7 SP1 (64-bit). (Please don't ask why I'm still running Windows 7!)

    Thanks.

    @jameslo I guess it's more complicated than I thought. It seems it would also depend on whether you're listening to speakers or with headphones? The article only talks about listening on speakers in large or small rooms. The -4.5dB law uses both square root and sin/cos functions, though, not just the square root, as described in the book I mentioned.

    I should have explained what I'm trying to do. I want to develop a patch in which the sounds move back-and-forth across the stereo field, their position isn't static. I want the movement to sound as natural as possible, though. I'll just have to experiment, I guess.

    P.S. The square root method is described in "Programming Sound with Pure Data" by Tony Hillerson on pp. 89 - 90 of the 2014 edition, if anyone wants more details. I couldn't find anything about equal power panning in Miller Puckette's book, "The Theory and Technique of Electronic Music". But if anyone knows of any books or articles that deal with the subject, please let me know.

    @jameslo Interesting article, but it doesn't say how it's calculated, it just refers to the amount (-3. -4.5 or -6dB). I don't have to be concerned about converting to mono, either. If I wanted a mono version, I'd just create it as mono in the first place. But thanks.

    Which is the "correct" way to implement equal power panning, using square roots or cosines? After doing some googling, I found posts recommending both methods. And which would be more efficient, if they're both "correct"? I've tried both and they both sound the same to me, and seem to give the same results, as far as I can tell. I compared the output from [env~] of the input signal with the summed output signals (left and right), and didn't see any difference. When panned near the middle, the RMS of the output signal is a little higher than the input signal, using either method (see screen prints below). But that may be due to the way [env~] calculates RMS, I don't know.

    Here are my two implementations, [pan~] using the square root method and [pan2~] using the cosine method.

    I guess not.

    @Il-pleut Yes, but I'd like to know if anyone is still supporting it. It appears to be abandoned, there's no contact information on the Google Play page, just a name, and it hasn't been updated in over a year.

    Does anyone here use PdDroidParty? I downloaded some zip files containing examples, etc., from the web site (https://droidparty.net/), but when I try to unzip the files, I get the error below. And the link to the GitHub repository seems to be broken. Is it still being supported?

    @seb-harmonik.ar For now, I don't need to cross-compile. And even if some day I do decide to share on Github or whatever, I don't really feel comfortable releasing something for all platforms if I'm unable to test it myself. But I guess most people are faced with the same problem, unless they have access to machines running all three OS's.

Internal error.
