I have finally uploaded a very short summary of the results of my bachelor thesis. It can be found in the new Research section on the subpage Tube Preamp.
As mentioned before, the topic of the thesis was to develop a digital simulation of a tube preamp. Actually, the algorithm was implemented on a digital signal processor (DSP). In addition to that, I have built a 32-bit VST plugin that uses exactly the same algorithm to emulate the preamp. This plugin is available for free. Comments and suggestions are welcome!
If someone is interested in reading the whole thesis (German only), just drop me an email and I’ll send you the .pdf file.
Last friday, I submitted my bachelor thesis titled Real-time implementation of a tube preamplifier in order to distort discrete audio signals. I have written the thesis in cooperation with d&b audiotechnik GmbH. Working for d&b was very exciting and I’ve learned a lot about digital signal processing. Within the next few weeks, I’ll present some of the results of my work on this website.
I’ve built a Linux version of phi-T Effect S. It works perfect with Ubuntu Studio 11.10, but I haven’t checked other Linux distributions yet. The supported audio driver is ALSA (the Advanced Linux Sound Architecture), which also provides MIDI functionality for phi-T Control. JACK audio is currently not supported, but this would be a cool feature, especially for Ubuntu Studio.
With my Native Instruments audio interface the latency is lower than 10 ms, hence not hearable.
To download the executable, see the project’s page in the tab above.
I’ve just finished phi-X, an ATmega8 based metronome with speed trainer. Very easy to build and low-cost. Details in the tab above!
Moreover, I created two short videos, to introduce both phi-T and phi-X. You can watch them on the corresponding pages.
In spring I came back from my internship in Berlin, to finish my studies here in Ulm. Luckily, the last two semesters were not that stressful, so I had some time to work on my own projects. Finally, I’ve created this website to introduce some of my work. The most recent, is phi-T, a digital effect system for guitarists.
I’ve already some new ideas, but I’m afraid, I won’t have much time during the next months, since I’m going to write my bachelor thesis about audio DSP in March.
Anyway, I’ll try to keep this website up to date and I hope it provides some interesting information about audio software and hardware.
