Improved, no. Kept what you'd find in Sound-* in Squeak up to date? Sort of. Though there were problems with loading it in 1.2/1.3 I'm not sure was resolved correctly, you can find the code in PharoSound repository on Squeaksource. As for improvements, you could check out http://forum.world.st/ANN-SqueakMovieMorph-Alpha-plays-any-video-file-playab... (make sure to use a VM including the plugin) Cheers, Henry
We should have a look at it. Argh we should really improve the way we manage the image after RPackage I will put that top of my priority. stef On Aug 8, 2011, at 9:51 AM, Henrik Johansen wrote:

That's unfortunate. :-( Ok. thanks for the reply. On Mon, Aug 8, 2011 at 00:51, Henrik Johansen <henrik.s.johansen@veloxit.no> wrote:

yes but if nobody helps we cannot do everything. What are you looking for? Stef

(I created a msg, but it went to the bit bucket some how.... See if I can remember what I wrote) There are various native packages - MIDI, FM, wav, piano roll music player, etc. and external ones like Siren, mu0, but I'm looking for interactivity. If Squeak/Pharo had tools to create audio content where the composer could build interactive music, or the sound designer was able to adjust audio parameters dynamically, it would allow content designers - or even product designers - a way to build audio richness into their products. Let's take a vehicle, like a car, as an example. Usually, not always, but usually sound designers will record various samples of an car engine at different engine RPM settings and at different engine LOADS. At playback, these files will be crossfaded to build a coherent engine sound. In a simplistic set up, the pitch of the first sample will be shifted until it reaches the crossfade area of the next sample... and on it goes up to the highest RPM. In this way, a full engine sound can be created by just changing the pitch (the reason for the crossfade is that a sample can only be pitch shifted so far and beyond that will sound artificial.) To make it more realistic, another variable, LOAD, is added which allows crossfading between two samples, at the same RPM, to allow timbre to change -- simulating engine load Ok, too much information. But, you get the idea. Having a tool to build this interactivity (it doesn't have to be as synthetic as the example) and then using the resulting assets to be added to a product (hmmm, like the EToys car demo) would allow interactivity.. more than just selecting a sound to play, which is what we have now. For an example, see FMOD Designer (http://www.fmod.org/index.php/products/designer). Free to download/use. Something like this, with an accompanying engine, could probably be easily built in Squeak or Pharo. b

Ok if you want that you should build a roadmap and start assembling pieces that exist and people will certainly join. Now we are musicians (except people from the Haute ecole musicale de Geneves)so this is difficult for us to work on that. Stef On Aug 9, 2011, at 3:23 AM, Brad Fuller wrote:
