Todays digital-mixing-consoles are offering high number of audio-channels for processing. I was curious of how modern devices are dealing with realtime digital audio-data and had a look into some of these protocols. I2S, TDM and UltraNet Even if you are not working with professional audio-equipment, at least one of the following systems has been used…
Join Elektor editors Brian Tristam Williams and Jens Nickel for the Lab Talk, where we’ll explore FPGA-based audio processing with Dr. Christian Nöding. We’ll discuss Christian’s FPGA audio player project and touch on other related topics, including audio latency and Bluetooth LE What’s on the agenda?
Using an Arduino MKR Vidor4000 board I created a realtime multi-channel audiomixer with nice audio-processing-features. General background Sure, digital logic has ones and zeros – but in the right order these two states can have an impact on your sound. I wanted to know how digital logic can be used to change the volume and…
On this blog I’m writing about my individual projects during my free time. In the past I started to write some articles on my website www.pcdimmer.de, but a blog seems to be a better place to talk about these projects. Some of them are about smart-home, some about FPGA-development and some about Retro-Computing.
In this video I use my FPGA audio player (FBAPE = Fpga Based AudioPlayer with EQs) built in a previous video to build my own DIY expansion card for the Behringer X32. The new card receives 32 audio channels with 24bit at 48kHz, processes them and sends 32 channels back to the X32. So, the…
This video shows the construction of our FPGA based full-digital Class-D amplifier and the participation at the finals of the IFEC2024 in Austin, Texas, USA. In July 2024, I took part in the IEEE IFEC 2024 competition together with several students of the University of Kassel. Our device has three channels with each 135W at…
In this episode I take you with me creating an audio mixing console based on the Arduino Vidor 4000 FPGA board. The final device has five EQs, a noise gate, an audio compressor and up to 22 channels with a total latency of 20.8 microseconds at 48kHz. Sourcecode and more: https://www.github.com/xn--nding-jua/Audioplayer Soft- and Hardware for…
In this video I take you with me to upgrade the hardware and I will describe some parts of the software of the DIY controller. In 2013 we changed the regular spotlights of our church to LED bars. But rain and UV-light did their contribution and damaged the devices so that I upgraded the installation…
In this youtube-video I bring a broken Behringer P16-I back to life to build a FPGA-based audiomixer. For this I’m using an Arduino MKR Vidor 4000 board with a SAMD21 microcontroller and an Intel Cyclone 10LP FPGA for the signal-processing. The audio-output to the analog world is done using a SPDIF adapter as well as…
