DDMF phi-L Audio Tube Preamp v2.0.2 x64 x86 VST VST3 AU AAX WiN MAC [FREE] 0 (0)

What is it?
This tube preamp emulation has been developed Philipp Bulling as a thesis work. Philipp has been offering the plugin in VST format for some time on his own website. He has now moved on to new areas for some time already but didn’t want to let down his users. Hence, DDMF took over the code and will continue to offer the plugin as freeware, with the intent to further improve it and maybe add some more bells and whistles in the future.

The plugin is very unique in the sense that it gives you full control over all aspects of the modelled circuit. All values of all the capacitors, resistors etc. can be tuned by the user. Here is what Philipp had written on the original page.

AbstractSince the sound of an analogue tube amplifier has always exerted a strong fascination, electrical circuits with tubes play a certain role in the world of audio engineering up to now. On the other hand, audio technology becomes more and more digitised. In many cases, digital models emulate real devices in such a way that differences in sound are hardly audible. In this work a model is developed which is able to emulate the typical sound of a tube amplifier on digital devices. Here the main focus is on preamplifiers with triodes, since they have a particular influence to the sound.

Based on the physical properties of real tubes, a tube model is developed first. This mathematical model includes results of theoretical studies as well as analysis of data sheets. The model is then used to implement an entire amplifier circuit. In addition to the tube itself amplifier circuits contain several passive elements. In the domain of digital signal processing the latter are described by finite difference equations, which are solved recursively.

The resulting algorithm is finally implemented as an audio plugin in order to examine its tonal properties. The behavior of the digital model corresponds satisfactorily to real amplifier circuits. Important sound effects of analogue tube amplifiers can also be attested to the digital model.

Diode modelThe first step was to develop a triode model, based on the characteristic curves of real tubes. In theory, the characteristic curve of a vacuum tube is described by Langmuir-Child’s law. However, it was quickly realised that compared to real tubes, this law is not accurate enough. So a new model has been developed. This model describes a triode as a mathematical function. With the model, it is possible to compute the plate voltage (Upc) as a function of the grid voltage (Ugc), depending on the working resistor (Ra) and the supply voltage (Ub).

The following graph shows this function for a 12AU7 triode with Ra = 10k and Ub = 250V:

Circuit modelingBased on this model, a plate follower stage was implemented.

Cathode biasingIn this circuit, cathode biasing is used to adjust the bias point of the tube. This is realised by a resistor (Rc) and a capacitor (Cc), placed between the cathode and ground. The effect of cathode biasing can then be modeled by a simple first order RC low pass filter, with Ic*Rc being the input of the filter, and the cathode voltage (Uc) being the output.

If the input signal jumps for example from 0 V to 5 V, the cathode voltage follows quite similar to the step response of a RC-low pass filter:

Signal limitingThere are two reasons for signal clipping in this circuit. The first one is caused by the tube itself. If there is a high peak at the negative half-wave of the input signal, the tube can’t amplify the signal anymore since the flow of current is completely cut-off. Thus, the positive half-wave of the output is clipped. This effect can be intensified by a more negative bias point.

Here the bias point of an 12AU7 is at around -12 V:

High peaks of the positive half-wave of the input signal make the grid voltage positive compared to the cathode voltage. In this case electrons are attracted by the grid. The grid current causes a voltage drop at the internal resistance of the previous stage, which limits the input signal. The following figure shows the effect. The grid voltage is obtained by shifting down the input signal (Uin) by the cathode voltage (Uc). In the upper picture the maximum grid voltage (Ugc) is ~ 0 V compared to the cathode. Hence, there is no grid current. In the lower picture the input signal has an amplitude of 10 V. At the positive peaks of the input signal the grid voltage rises above 0 V (compared to the cathode). The grid current begins to flow and clips the grid voltage.

Im letztem Herbst produziert
im November war ich an einem Samstag zum Spazierengehen verdammt, den ganz in der Nähe, wo ich wohne, wurde eine Weltkriegsbombe bei Bauarbeiten entdeckt und wir mussten alle unsere Wohnungen verlassen. Da Lockdown(Corona) herrschte, konnte man die zeit nicht in einem Lokal überbrücken, also bin ich in meiner Gegend rumgelaufen und habe den Speicher meines Handys vollgeknipst. Den Track hatte ich ein paar Tage vorher gemacht.

Last autumn produced
in November I was condemned to walk on a Saturday, the very near where I live, a world war bomb was discovered during construction work and we all had to leave our homes. Since Lockdown(Corona) prevailed, the time could not be bridged in a pub, so I walked around in my neighborhood and have the storage of my cell phone full. I had made the track a few days before.

Style: New Age/World
BPM: 60
Instrumente: VB1, Spectror, Mystik, Flute und als Besonderheit eine Hu-Lu-Si aus China

Die Hu-Lu-Si ist kein Doppelrohrblattinstrument sondern erzeugt die Töne über metallene Durchschlagzungen wie bei einer Mundharmonika.
Über eine Kalebasse, welche als Windkammer dient, werden zwei Pfeifen angeblasen. Die mittlere Pfeife ist als Melodiepfeife mit Fingerlöchern versehen, eine seitliche Pfeife klingt als Bordunton mit.
Die Metallzungen erzeugen weiche vibrierende Töne, ähnlich einer Mundorgel.
In verschiedenen Tonarten erhältlich.

Berklee Indian Ensemble featuring Ustad Zakir Hussain – Lady L (Live at Berklee) 0 (0)

The Berklee Indian Ensemble is proud to present “Lady L” featuring Grammy-winning Indian tabla master, Zakir Hussain. Composed by L. Shankar and featuring John McLaughlin, “Lady L” was originally performed by ‘Shakti’, the 1970s indo-jazz fusion group and appeared on the group’s second studio album titled “A Handful of Beauty”. The group featured John McLaughlin (guitar), Zakir Hussain (tabla), L Shankar (Violin) and Vikku Vinayakram (Percussion).

In 2019, Berklee College of Music presented Ustad Zakir Hussain with an Honorary Doctorate. It was the perfect opportunity for our Berklee Indian Ensemble musicians to reinterpret such an iconic composition and collaborate on this live performance with Ustad Zakir Hussain as part of our week long celebration of the maestro’s life and musical accomplishments leading up to his Honorary Doctorate ceremony.
