HTML5 Audio Player Demo

Patrick — Thu, 08 Apr 2010 18:19:50 +0000

SoundCloud wouldn’t be that popular if the player didn’t show the waveform image. The HTML5 audio element makes it possible to realize such a player without Flash. As browser support varies at the moment (Firefox seems to lack the JavaScript interface to access how much of the file is already seekable; also most browsers either support OGG Vorbis or MP3) this demo only works only on Apple Safari 4 or Google Chrome 3 (or later). Hopefully these problems will get sorted out in the future. Actually it works best with Safari 4.

Add XSPF support and maybe a little AJAX magic for comments and you have a very nice audio player in your browser without any Flash, using the audio and canvas element.

Waveform images are generated by waveformgen, music is performed by my laptop band Benoît and the Mandelbrots.

waveformgen

waveformgen is a little tool to generate simple waveform images out of an audio file. It’s very basic and nothing special. I needed a tool to generate waveform images for a web application, so I thought i might write it myself as a little C exercise.

The source code is released under GPL.

Some Updates

Patrick — Sun, 14 Feb 2010 15:55:34 +0000

I’m not that much into blogging at the moment, but here are some quick updates:

Grainface disbanded some months ago but I now play in the laptop band Benoît and the Mandelbrots which could be described as “Post-Grainface” :-) We have a nice video on Vimeo.

I did some music in pure C and it was played on the ComputerStudio Konzert in the ZKM under the name “3 Studien in C”. One of these studies is available on the site of the Public Pixel Matrix, as it uses data from it. They also got mixed together with dance music by Friday Dunard.

Some of my recent coding can be found on GitHub. I also tried to locate (and/or fix) some bugs in SuperCollider, but i still lack insight in the sources and my C++ isn’t at that level at the moment.

Well, I think this is everything new i can say about “cappel:nord”.

Where can i find MPHP3?

Patrick — Sun, 13 Dec 2009 13:42:30 +0000

For anybody who looks for the MPHP3 PHP class I wrote several years ago when i was still in school (and had time to do such stuff):

I put it offline, because it had several issues and I’m not into PHP anymore. I think it’s fascinating how much it got used, but I also think that you can find better maintained libraries to do this job. I think php-reader looks decent but I haven’t tested it.

I wonder on how many sites it is still used. Googling it at least reveals some sites by error messages from within the file. Thanks to everyone who suggested it as a solution for the problem of computing the duration of a MP3 file or reading ID3 tags within php.

Public Pixel Matrix Processing Library

Patrick — Sat, 29 Aug 2009 16:36:04 +0000

A first version of the Processing library for the Public Pixel Matrix is now available on GitHub. It is in a very early stage. Many features and other fixes to come.

I also posted the results of a first experiment on YouTube.

I started to move some other stuff to my GitHub Account too. I hope this will cure my bad habbits to leave most of my sourc ecode uncommented and undocumented.

Public Pixel Matrix

Mein neues Projekt Public Pixel Matrix ist ein Versuch einfache kreative Entscheidungen von Internetuser aufzuzeichnen, um sie dann später in andere Bilder, Videos, Sounds oder Musikstücke nutzbar zu machen.

Ich möchte an dieser Stelle nicht viel darüber schreiben. Auf der Homepage findet ihr alle relevanten Infos.

AnnounceOSC

Patrick — Tue, 24 Feb 2009 13:27:24 +0000

Because i found it kind of sad, that OSCulator is discovered by TouchOSC via Zeroconf/Bonjour and SuperCollider is not i hacked together a tiny Java Application.

AnnounceOSC on GitHub

I found Inspiration and some help on Moritz Haarmann’s Blog. Use the Application at your own risk – even for announcing Max/MSP ;-)

Puls8r

Patrick — Mon, 16 Feb 2009 16:11:00 +0000

In den letzen zwei Wochen habe ich den Großteil meiner Nerd-Zeit hauptsächlich mit zwei Sachen verbracht: Koreanisches Profi Starcraft und mit der Entwicklung eines Audio Unit Instruments, dem Puls8r.

Sobald das Instrument etwas reifer ist (meine C++ Skills hinken leider noch etwas hinterher) wird es natürlich auf dieser Seite zum Download bereitstehen. Heute aber erstmal nur ein kleiner Klangeindruck:

Folgendes Klangbeispiel ist ein gerendertes Arrangement aus sieben Puls8r Instanzen (mit etwas Hall), importiert in Live und etwas langsamer geregelt (Warpmode: Beats). Dazu noch eine Basedrum aus Live. Die Basedrum ist der einzige Sound der nicht von Puls8r erzeugt wurde. Man merkt schon: Der Sound richtet sich eher an die 8-Bit Freunde, aber vielleicht werden auch andere Spaß daran haben.

Direkt MP3
