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.

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.

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.

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.

Plug&Play is a mystery to you? Until recently it was for me too, but let's take a look at the PCI specifications and lift the fog of mystery about PnP.

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.

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

Using an Arduino MKR Vidor4000 board I created a realtime multi-channel audiomixer with nice audio-processing-features.

In the next weeks I will write something about my individual projects on this blog. In the past I started to write some articles on my website www.pcdimmer.de, but a blog seems to be a better place

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.
