Today I published the new 1.2.0 Release of my ESP32-A2DP Library. It contains the following improvements: Metadata support with the help of a callback function – Thanks to JohnyMielony AVRC command support thanks to PeterPark Improved init_bluetooth checks, in case bluedroid was already initialized elsewhere – Thanks to Antonis Katzourakis Read more…
I am quite enthusiastic about the new Raspberry Pico. However I find the C SDK not very friendly and I prefer to have something as simple as the Arduino API. I did not want to wait for the official Arduino support – so I started my own project. The last Read more…

The first thing I wanted to try out after I have received my Piezo Buzzer was to generate some simple beeps. In Standard Arduino there exists the tone() function which – unfortunately – is not available in the ESP32 Arduino implementation. There are libraries to bridge this gap, but I Read more…
In one of my last year’s posts I was describing how to build an Internet Radio using an ESP32. I was using this together with an external DAC to feed an Amplifier. Lately I got some really cheap Piezo Electric Elements and I was wondering if I could use the Read more…
Im my last post I was describing how to set up BlueAlsa on a Raspberry PI to use the PI as a a2dp source. Unfortunatly this is a little bit more complicated in Armbian because the project is not available in a Respository. Fortunatly I found some instructions created by Read more…
I was asking myself if I can use a headless Raspberry PI Zero together with a MIDI keyboard as simple Synthesizer which sends the sound via A2DP to a Bluetooth Speaker. So technically speaking I wanted to set up my PI as a2dp source. Installation Initially I tried to do Read more…
I made the Synthesis ToolKit (SKT) available as Arduino Library. The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with Read more…
Overview The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. You can find further information in the original Readme of the STK Project Like many other sound libraries it originates from an University (Princeton) Read more…
