SoundManager

From the SoundManager website:

“Using HTML5 and Flash, SoundManager 2 provides reliable cross-platform audio under a single JavaScript API. (…)

SoundManager 2 gives you a simple but powerful API that supports both new and old, using HTML5 audio where supported and an invisible Flash fallback where needed. Ideally when using SoundManager 2, audio ‘just works’.”

Beyond HTML5: experiments with interactive audio

The combination of HTML5, JavaScript and the evolution of browsers will allow for audio manipulation and visualization similar to what can today be achieved with Flash.

David Humphrey has been experimenting on top of Mozilla’s extensible platform. His explorations can be found at the Mozilla Hacks Blog:

One example, quoted from Mozilla Hacks: “(…) done by Jacob Seidelin, and shows many cool 2D visualizations of audio using our API. You can see the live version on his site, or check out the video above.”

Flash sound update

About a year ago I posted about the new sound capabilities in Flash player 10:

http://mlab.taik.fi/mediacode/archives/110

It seemed to be a direct result of the “Adobe Make Some Noise” campaign:

http://www.make-some-noise.info/

Although the results were not what was expected originally, they are still very useful. This post from the previous website sums it , and points to some other useful links:

An impressive result of this is Hobnox audio tool:

Some additional examples:

Recently Matti posted about the excellent Popforge library, developed by the same people involved in the “Make some noise” campaign and Hobnox:

Popforge is very powerful, but the learning curve can be a bit high. Some simpler to implement alternatives could be:

1) Antti Kupila’s SoundFX:

2) Fredrik Johansson’s take on Popforge:

Meanwhile, here is an interesting tutorial from Adobe:

In my opinion, this tutorial highlights the advantage of using pre-made libraries instead of building from scratch…

Popforge Sound Library (AS3)

Popforge sound library is bundled with many sound processing and manipulation possibilities. The library is developed by Andre Michelle and Joa Ebert.

Please note that Flash example files are under trunk menu. One needs to download them as well as the whole core lib package. Below are links to the files.

Detecting microphone activity

I found this on the Adobe website:

Programming ActionScript 3.0 > Working with sound > Capturing sound input > Detecting microphone activity

http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00000301.html

It’s still in the Flash 9 documentation, but might be useful for a simple sound detection application.

Flash 10 – Adobe makes some noise

Adobe is developing Flash 10 Player:
http://labs.adobe.com/technologies/flashplayer10/

You might be aware of the “Adobe, Make Some Noise!” campaign to bring more sound features to Flash:
http://www.make-some-noise.info/

Well, it seems Adobe is making some noise. Check out Tinic Uro’s blog:
http://www.kaourantin.net/2008/05/adobe-is-making-some-noise-part-1.html
http://www.kaourantin.net/2008/05/adobe-is-making-some-noise-part-2.html
http://www.kaourantin.net/2008/05/adobe-is-making-some-noise-part-3.html

Tinic Uro is a Flash 10 developer. In his words:

Yes, in Flash Player 10 you will be able to dynamically create audio. It’s not an all powerful API, it is designed to provide a low level abstraction of the native sound driver, hence providing the most flexible platform to build your music applications on.
(…)
With what we provide in Flash Player 10 we hope that we are addressing the most pressing needs of what you want to do with sound. I will likely be just a matter of time until we’ll see high level frameworks done by the community on the magnitude of something like Papervision3D. The next couple of years should be very interesting indeed when it comes to sound on the web.

Although a lot has yet to be done for turning Flash into a powerful audio development platform, the door has been opened and the future looks bright. In my opinion, this is quite exciting for developing online audio tools, and will lead to some revolutionary events in the sound world. Stay tuned…
