Without the possibility to adjust the volume of individual frequency bands within an audio signal, modern audio would not sound the same. Today I’d like to show how I’ve implemented a EQ within my FPGA audio-mixer. In this blog-post I won’t describe the general idea of an EQ, because there are more capable persons available…
Based on my Audioplayer-project I developed a DIY card for the Behringer X32. In addition to the youtube-video here you will find some more detailed information about this project and the implementation. Definition of reverse-engineering by Elliot J. Chikofsky: “Reverse-engineering is the process of analyzing a subject system to identify the system’s components and their interrelationships…
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…
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.
