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…
In this video I’m testing the DIY Expansion-Card for the Behringer X32 audio-mixing-console with the Room-EQ-Wizard-Software and I’m showing the new workflow using XTouch-Controllers and more things. With a live-mixed 64-channel song I’d like to celebrate 6.400 subscribers. Thank you so much for your interest, the support and the nice feedback via eMail or the…
Implementing an audio-compression-algorithm in pure logic is a bit challenging as it uses a division. Time for some deep-diving into audio DSP with VHDL. Background As I’ve started implementing logic for the FPGA-Audiomixer, first I had not planned to implement more enhanced audio-functions. My primary goal was to understand how a volume-control could be done…
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 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…
