LAC
by Kassen 08 Apr '10

08 Apr '10

Fellow ChucKists, At the start of the next month the city of Utrecht (NL, EU) will host this year's Linux Audio Conference. There I'll do a workshop on ChucK but there will also be a panel discussion on various programmable open systems for audio (SC, PD, CSound, Nyquist, maybe more). This should help clear up many of the things that are unclear (to many) about the differences between these systems. The results of this will be posted online where they will hopefully help prevent flame-wars or at least give more substance to any that do arise. Of course this will involve some quick demonstrations. This leads to the question of what ChucK is especially good for as compared to other systems. Time for this will be brief in this context so I'd like to show some good stuff. I have some ideas of my own but I'd like to consult the list too. What's especially useful/fun to you? What (positively) surprised you compared to other systems? Debate, anecdotes and code examples are all welcome. Do come shake hands if you end up going to the LAC; at 2m with a afro I'm quite hard to miss. Yours, Kas.

wiimote hacks?
by David Loberg Code 06 Apr '10

06 Apr '10

I have seen scattered postings related to wiimotes and ChucK, but nothing definitive. Is anyone out there using wii-remotes or nunchuks as controllers for ChucK? Are there any wikis or recipes for this kind of hack? If not wii, is there some similar game controller (e.g., wireless with motion sensor and buttons) that is more easily adaptable to ChucK? david David Loberg Code School of Music Western Michigan University Kalamazoo, MI 49008 code(a)wmich.edu

Ge on Nightline

I just can't resist pointing out that I saw Ge last night in TWO different clips in an ABC Nightline piece on the Apple iPad. World renowned! In the second clip, an iPad had what looked like a circular piano keyboard. -Bill

Guile C++ wrap
by Hans Aberg 31 Mar '10

31 Mar '10

I started to write a bit on a Guile C++ wrap*), and it strike me it may give some inputs on the discussion on giving ChucK functional language capabilities. First, Guile has a conservative GC (meaning that it just tries to collect some pointers, not necessarily all). It makes C++ implementation very simple: you don't have to write operator=() and copy constructors, because normally, when an object is mutated, it is being done using *this = f(*this) where f is a function of the functional language (so normal object referencing just needs to hand over the pointer). But the question is if such a GC can be made without causing timing problems. Then I use templates to do some Haskell style static typing, though C+ + is a bit too limited. But it is fully possible see what kind of syntax might be possible. For example, one can define an increment function using function1<integer, integer> inc = x >>= x + 1 (though I must use a more complicated syntax in the actual code due C+ + and Guile limitations). Here, ">>=" is the lambda, and in math it is the symbol ↦, in ASCII looking like |->. The Haskell-like define-function-by-cases syntax would be something like: function1<integer, integer> inc; inc(x) = x + 1; though it is hard to get it to instantiate properly using C++ templates. But if built into a ChucK parser, that should be no problem. But it seems that the current ChucK syntax might be enhanced with functional language features. Hans *) http://math.su.se/~haberg/guile/

CIP (ChucK Instrument Processing)
by Scott Hewitt 31 Mar '10

31 Mar '10

Hi all, Would like to take the opportunity to introduce everyone to CIP (ChucK Instrument Processing) http://cip.ablelemon.co.uk/ Basically an easy way to link up ChucK audio processing with a GUI within the miniAudicle on OSX. Interested in peoples comments about it. all the best Scott

Re: [chuck-users] chuck-users Digest, Vol 56, Issue 18
by Michael Hammond 30 Mar '10

Thanks all for your responses. Just to clarify, my hope is to make a standalone app that can randomly select among 20-30 sound files to play back 5-8 simultaneously as a single "track." The hope then is that users can move to different points in the playback of the "track" just as they would in an MP3 player like itunes. I like the command-line idea, but it seems like jumping to different parts of the audio files might not be possible. Is that true? Perry, I'll look into the chunks idea when I get home. I like it because it would allow me to keep everything in ChucK. My only concern is that pausing playback to periodically load new chunks into the buffer would result in stutters. Does anyone have any experience with this? Thanks!

The command-line gui-free approach can be done in Windows also, using DSrender.exe, which "plays" almost any kind of media. Oops, I've been using that for so long I forgot that it didn't come with Windows but was instead a sample app from a book that I read: http://www.microsoft.com/mspress/books/sampchap/6381.aspx I don't know how good an idea this is but I can zip up the 164Kb executable and mail to anyone to try. -Bill > From: Robert Poor <rdpoor(a)gmail.com> > Michael: > If you're on a Mac, and If you're comfortable with simple command line > programming, have you considered using the "afplay" command? <...> > On 2010Mar29, at 08:26, Michael Hammond wrote: >> i have a quick question for all you audio programmers out there. >> so i'm looking for the quickest, cheapest way possible to play large >> quantities of audio (preferably wav or aif files). <...>

Michael (and all), You should investigate the .chunks option for SndBuf: .chunks - ( int, READ/WRITE ) - size of chunk (# of frames) to read on-demand; 0 implies entire file, default; must be set before reading to take effect. // Example: SndBuf b => dac; 1024 => b.chunks; "Beethoven5thSymphony.wav" => b.read; while (1) { 1.0 :: second => now; } PRC > > 1. minimizing load time for tons of audio (Michael Hammond) > > 2.
