xplanetFX renders high quality wallpapers of mother earth on your desktop. An extensive GUI (GTK) provides a lot of features and settings. Various templates place the planet inside different scenes and make shure your desktop never gets boring again. With realtime light, shadows and clouds!

traGtor is a graphical user interface for the awesome conversion tool ffmpeg. With multi streams, presets, multi language and a lot of other features traGtor is a handy tool for converting all audio and video formats through ffmpeg. traGtor is based on GTK and Python.

Calf studiogear is an extensive and high quality plugin pack for professional audio production under Linux. It provides a lot of synthesizers, effects and signal processing for the use with LV2 audio production suites (like Ardour) or as stand-alone through JACK.

Calf with all of its new features and processors isn't officially released by now so you have to grab the GIT-repository from sourceforge.net until we are ready for a stable release.

guess is a tool to launch (and kill) different setups of programs. It was invented to startup all needed synthesizers, audio suites, MIDI sequencers and stuff with the correct source files on the right desktop for a single audio production with just one click.

Calf Studio Gear: New Website, New Domain, New Repository

Donnerstag, den 28. Mai 2015

Calf_Studio_Gear_GNU_Linux_Audio_Plug_Ins_IceweaselWe’re proud to introduce our new web „experience“ – a new website with a new domain and a new repository. Unfortunately we lost lots of great reviews, all bugs and feature requests and so on but we couldn’t stand the actual behavior of SourceForge anymore. There was a discussion among us about this topic and today Krzysztof made me aware of this one so we decied it’s time to finally leave SF and to publish the new website in that course.

The most promising solution was GitHub, so we moved the repository over there and we will use its issue system for tickets in the future.


The new website is now available at:


…which is also much faster than the SF webserver. I informed all owners of open bugs but once again: sorry for any inconvenience!

If you are experiencing any problems with the new website feel free to report them here. Thanks in advance.

And please remember to update your Git config to „url = https://github.com/calf-studio-gear/calf.git“!

Hint: This is not what I meant with „what I was working on the last few weeks“ yesterday…

Calf Studio Gear: Transient Designer With Filter For Envelope Detection

Donnerstag, den 12. März 2015

Calf - Transient DesignerLately I added a requested feature to Transient Designer – A high pass and a low pass filter to narrow the frequency range of the signal Transient Designer uses to determine the envelope. This is useful if there are some cross-talks in the signal (e.g. hi-hat on a snare drum track) or if you want to edit single instruments in a drum sample. A „Env Listen“ button lets you monitor what you’re doing. Additionally the UI has changed and the waveform graph was cleaned up – optically and in the code.

Furthermore Chrischi and me had an extensive session where we fixed a reported and quite tricky bug – Transient Desinger sometimes lost its output due to rounding errors on floats. We raised the accuracy of the transient detection in the course of the fix.

Calf Studio Gear: Envelope Filter with Reponse Curve

Donnerstag, den 29. Januar 2015

Calf Envelope Filter DiagramThanks to Chrischi the new Envelope Filter has a response curve for the transformation from gain of the envelope to the frequency of the filter. This means that one is able to adjust the behavior of the filter exactly to the dynamic the material provides. 0% response means that a signal of -6 dB will set the filter to the frequency in the middle of upper and lower frequency, -12dB to 1/4 of the range. A positive response curve lets the filter reach higher frequencies on the same input, a negative setting reduces the frequency – all without moving the bias point set by the Activation knob (which simply moves this point). The graph shows the aprox. settings -100% (purple), -50% (green), 0% (blue), 50% (red) and 100% (yellow). This feature gives total control over the response of the auto-wah effect according to your material.

Chrischi, I want a child from you!!1

Calf Studio Gear: New Plug-In – Envelope Filter

Mittwoch, den 28. Januar 2015

Calf - Envelope FilterI’ve created two Calf Studio Gear videos lately, one more to come. The next one will focus on „real“ instruments, I’m planning to play some drums, bass, guitar and a drawbar organ. While doing the concept for it I stumbled over a gap in the Calf world – we didn’t have any Auto-Wah like effect by now! So I built Envelope Filter yesterday. One function is missing – taking the response curve of the envelope-to-frequency calculation into account which Chrischi hopefully will create later this evening. Other features are:

* Display for the frequency response
* Lower and upper frequency – switch them to have a downwards filter
* Different filter types (HP, LP, BP and Notch with different slew rates)
* Optional sidechain
* Resonance knob
* Mix knob

It’s in the GIT repository atm and hopefully it will make it into 0.0.60 \o/

Calf Studio Gear: Gotcha! Some plug-ins in action

Mittwoch, den 7. Januar 2015

The result is far from being perfect but you can at least see some of the Calf devices in action.

Calf Studio Gear: Now available in MOD

Looks like very solid and cool gear, seems I have to get one for myself.

31C3: Calf team comes up with a new pre-release

Samstag, den 3. Januar 2015

31c3-calf-devsOnce again Krzysztof, Chrischi and me met on the Chaos Computer Conference at the CCH in Hamburg/Germany. This year we decided to go for another release, namely 0.0.60. We managed to prepare the pre-release version and to update website and sourceforge with the latest developments. All in all there are about 44 plug-ins in the package now.
