Spread over all pages you will find some hints about software I use either for development or audio playback. At this point I would like to summarize these notes in a structured way.

Electrical Engineering / Electronics

Altium Designer

There are days when I use this software felt all day long. No other software I have in use as much as this one. It is a design system for electronic circuits. You can actually do everything around the PCB with this fantastic software, but working with it is complex and the price is not low – at least a professional tool.

LTspice

Although a SPICE simulator is also integrated in Altium Designer, I use the free SPICE simulator LTspice for my simulations. My first contact with a SPICE simulator was during my studies, at that time still without a graphical user interface. Somehow I kept working with SPICE, I still use text based input files. LTspice also offers a very nice graphical circuit input. The simulator comes with a lot of models that are now – because of the adoption of Linear Technology by Analog Devices – with the models of AD. However, my approach does not depend on the internal models and I can fall back on my now huge model library. I actually create each circuit in the simulator and so I use this software very intensively.

SigmaStudio

With SigmaStudio from Analog Devices you can graphically create the software for a number of digital signal processors (DSP) from this company. The DSP can be programmed directly from the user interface – if you have the appropriate programming adapter. A very nice tool that makes the entry into the world of digital signal processors very easy.

SDCC

A C Cross Compiler for microcontrollers under the GNU license. Meanwhile I create all programs for my x51 μC circuits with it. I have been using these processors with Assembler and C compilers for more than 30 years now. In the meantime I have accumulated a large collection of functions which I have ported to the syntax of the SDCC. However, this software is a pure compiler without any development tools. The programs are all started from the command line.

Code::Blocks

This software is an open source IDE for C, C++ and Fortran that works great with the SDCC compiler. It offers all the amenities you are used to from a complete development environment.

Flip

Flip is rather outdated from today’s point of view. With the help of this tool you can program some x51 controllers from Atmel via the serial interface In Circuit. With the sale of Atmel to Microchip the tool is very difficult to find. In addition, a serial interface is also required on the PC side. Who needs this software can contact me.

ScanaStudio

For very little money Ikalogic provides a logic analyzer with very nice software. I own the 4-channel SQ200 with 200MHz sampling rate and 4M Pts memory depth per channel. The software includes a protocol analyzer and can currently decode more than 30 digital protocols.

Audio Tools

2018/07/17

Roon

Roon is my favorite music player on my audio computer. Before I used this software I had read a lot of positive about it and was very curious. Roon presents your music collection differently than corresponding programs. You can learn so much about the musicians and their albums that you run the risk of reading more than listening. However, it also takes some time to get used to – at least for me. Today I don’t want to miss this software any more and I have a lifelong license. However, one disadvantage is not to be concealed at this point: All information is only available in English.

JPLAY

I use this software to transport the digital audio data from my audio server (Control-PC / Roon Core) to my audio player (Audio-PC) which controls my DAC. This software is especially written for this audio transport and turns 2 PC’s into audiophile components. If you’re serious about computer audio, I think you can’t get around this software.

Audiophile Optimizer

With the Audiophile Optimizer, Windows 10, Windows Server 2012 R2 and Windows Server 2016 systems can be optimized for audio playback. I now simply claim – based on my own experiences – that audiophile listening via computer is not possible without this software. Of course, this requires the use of the operating systems listed above. For me it is Windows Server 2012 R2, this software deactivates so many useless parts of the operating system that in the end only the pure playback functionality remains – with astonishing results. The documentation is very readable and you can learn a lot about computers in a high-end audio environment. In addition, the Audiophile Optimizer works wonderfully with JPLAY. Also here applies to me: Who is seriously engaged with computer audio does not get around this software.

Acourate

Although I do not use this software myself, it has already done an excellent job for me. The manufacturer describes the software as the High-End Audio Toolbox. My friend Heiner uses them for a lot of audio measurements. For me we use the software for measuring the room and here especially for measuring the reverberation times for setting the SubDSP and active absorber. A great tool, but you also have to be able to handle it. For this reason I always rely on my specialist and have not yet bought the software myself.

ARTA

A similar tool to Acourate is ARTA. It certainly has a similar scope, but it is cheaper to get. One disadvantage should not be ignored here: the reverberation times can only be measured down to 60Hz with ARTA – here Acourate can more, one of the reasons why we use this tool.

dBpoweramp

I use this great tool collection as a ripper for CD’s and for converting audio data. According to the experience reports and also according to my own modest opinion, the CD Ripper is the best in its field that is currently available. The money for a license is in my opinion worthwhile in any case – at least then if one hears like I his digital music only from the computer and one is dependent that the own CD’s are properly read in.

Mp3tag

A very comfortable tool for editing tags in audio files. A large number of audio formats and tag types are supported. Queries to common online databases for the automatic transfer of information including cover images into the tags can also be carried out. A simple way to rename audio files using the stored tags (or vice versa) is also implemented.

MusicScope

The company XiVero offers a range of tools around audio files on the computer. The best known tool is the MusicScope which analyzes and visualizes a large number of quality features of an audio file. I mainly used it to check if a HiRes file is a fake or if there is actually a higher sample rate and bit depth. I also always test the ripped files for Inter Sample Peaks with this tool. To remove these peaks, XiVero provides another tool called AudioRepair.
