AS3 Failure?
August 8th, 2009
Intro
According to the posts from Joa Ebert and Nicolas Cannasse I put my personal opinion on stack. Starting with Flash4 I see the long run of Actionscript for 10 years. It became truly a serious language since then. Back at the time, where no type-safe programming was possible and Actionscript errors were caught silently by the virtual machine, it was a pain in the ass to debug and create bigger projects. I was used to that, so I never complained the situation. I had no experience in other languages which features would make me jealous. Everything I have ever wanted were new features, new possibilities to create graphics and deal with sound. So every new Flash version extended my tool kit and I spent a lot of fun-time with the new toys. The only thing that annoyed me was that Actionscript was the slowest language thinkable. That has changed 2005 with Actionscript 3.0, which I am very thankful for. Actionscript 3.0 came with some stunning new features like dealing with bytes on the lowest level, manipulating the display-list in runtime without destroying the DisplayObjects and the fastest language in the Flashplayer since then. And with Flash10, my dream of dynamic audio programming came true, after ringing the bell.

Pitch MP3
July 2nd, 2009
Pitching MP3 (Not PitchShift!) is possible since Flash10s new Sound API. Today I saw Lee Brimelow's post about doing so, providing some source code. Cause we spend a lot of time to keep things running more smoothly in the AudioTool, I created another version which has some advantages.
- No objects are created in runtime (memory usage)
- The SampleDataEvent is receiving a static blocksize (steady latency)
- Linear interpolation (sound quality)
- Speed can go down to zero

Flash on tap, Flashbelt and a tiny insight of the states
June 16th, 2009
Coming back from two weeks of traveling through the states with my co-worker Alan Ross. Starting in Boston, we attended Flash on Tap, where I spoke about Digital Audio Signal Processing in Flash10. FOT was great and the beer-tastings were delightful. A lot of local breweries shown up to present their beers. Cheers! Looking forward for next year. Thanks to Chris, Rebecca and the rest of the team!

Eclipse plugins you need
May 13th, 2009
Catchy title, worth to consider. While working on the AudioTool, we are continuously searching for better workflows. Joa Ebert has written two plugins for Eclipse that helps us a lot to deal with such a huge project.
To make it clear: I don't love Eclipse. It is still a love-hate relationship and I am often fighting against its philosophy. So far, nothing comparable platform-independent in sight.
MetaLaunch (free)
If your project consists of a bunch of SWCs, you often want to compile them first and your application afterward. Use MetaLaunch to launch several Eclipse launchers from a list.
PBDT - PixelBender Development Tool (free)
Adobe PixelBender Toolkit is not event worth to consider as a code editor, I am afraid. PBDT instead supports semantic highlightning and basic refactoring for your PixelBender shader source code. It even compiles your code in the background. This gives you a very nice workflow in developing shaders.
FDT - Flash Development Tool
Not to forget the sophisticated Actionscript development tool by powerflasher. People often think, you need to be an expert in Actionscript to get benefit from it and still prefer to use the Flash IDE. On the contrary, using FDT helps you learning AS3 with tons of useful features.

Trip to the states Flash on Tap & Flashbelt
May 12th, 2009
Time flies! Yet two weeks and I am heading towards Boston to speak at Flash on tap.
Lucky me, Flashbelt in just one week ahead then. Thus I decided to stay in the states and try to find a way from Boston to Minneapolis with my colleague Alan Ross. It is more than 2.000 km, so I am pretty sure, there are a lot of things that we should visit on our way.
(Any suggestion where to rent a car for the trip?)
We are free for proposals. I am personally more interested in nature than visiting big American cities, but if you live nearby our route and offer food and accommodation we could hang around for some beers and chat.

FFK09 Karplus Strong Sources
May 1st, 2009
As promised here are the sources from the 10 Hot Minutes session, where I presented a very simple Karplus-Strong algorithm implementation.
More sources from the session Boing Bumm Tschak can be downloaded here.
Endless Karplus Strong - Click to feed noise:
An enhanced version emulating a guitar can be found here.
It is basically the same code as above!
John Davey was able to make a very nice shot from Mario and me. Great conference indeed.

Development Tool Pixelbender
April 24th, 2009
Bothering about the Pixel Bender Toolkit? It is just a pain in the ass to work with an code editor that even does not provide simplest text selecting features as textEdit.
Joa Ebert developed a very nice Eclipse Plugin for Pixelbender coding, which also compiles Pixelbender code before compiling and launching your SWF. This saves a LOT of time. There is no need to open the Pixel Bender Toolkit at all.
Last thing I am waiting for is a command line compiler from Adobe to allow one and two channel inputs. That would be great for audio processing. I am pretty sure, Joa would implement the compiler in no time.

ToneMatrix arrived in Hobnox AudioTool
April 17th, 2009
Okay, we did it. The same simple ToneMatrix is now implemented in the Hobnox AudioTool. To be honest, I wish we had more time to add more features to it, but at least you can mix now the little cute toy with drumcomputers, the bassline and add a couple of effects. Furthermore, as a registered user of Hobnox you are able to record your session and upload it in the community.
Some new features besides:
- Better performance while scaling the desktop
- Autoconnect (Removing an effect device will connect the source and the target automatically
Alongside we have completely rewritten the audio engine form the scratch, which is not part of the update. This already allows us to add automation and modulation. The audio event system is running with its own garbage collection, pooling all events to reduce glitches from the real garbage collection.
Furthermore there is event postprocessing (Ever heard a super-mario midi file shuffling?). We are working hard to make 1.0 a serious application. I cannot wait to see, what you guys will do with all that new stuff.
Listen to what our team member Alan Ross did with it:

The amazing ride of ToneMatrix
April 11th, 2009
This proofs it. The simpler the better.
I visited the Frankfurter Musikmesse 2 weeks ago and played with the Yamaha TENORI-ON. I thought, it would be much nicer when the triggered notes would force a wavemap to oscillate. It took me just a few hours to implement. The sound generation is basically a polyphone synthesizer with a simple delay with a variing read-offset to make the tones vibrating in the end. I am already addicted for myself to the cute sequences it always generates.
After uploading it on my laboratory the run began. I am counting more than 250.000 impressions, endless feedback, suggestions and even videos on Youtube. I will definitely put the sequencer in our AudioTool. But don't expect an update before autumn. We are trying to make 1.0 a serious music application with sequencing, automation, modulation, audio-tracks, synthesizers and what not. So there is no time to enhance this little toy. But I have added at least Clipboard support to let you save your pattern to sequence of numbers. Unfortunately the audio output is very glitchy when the context-menu is running.
Audio is the next big thing in Flash.
