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 I was playing with the idea to implement a simple Synthesizer for the ESP32.which would play different instruments. The ESP32 should have enough power to generate interesting sounds. The limitation however is on the memory. So any approach which relies on sampled data and big sound buffers will just Read more…
In the last couple of blogs I was setting the stage for my Radio Music Player for the ESP32. I was thinking first that I will use one of the many existing web based music applications together with my ESP32 Bluetooth Player. But I soon realised that either they want Read more…
The ESP32 provides a Bluetooth A2DP API that receives sound data e.g. from your Mobile Phone and makes it available via a callback method. The output is a PCM data stream decoded from SBC format. The documentation can be found here. I2S is an electrical serial bus interface standard used Read more…
The simplest way to stream music from a Raspberry PI to an external amplifier is to connect the headphone jack to the AUX Input of the amplifier with the help of a corresponding connector cable. From a quality point of view a better approach is to use an external Digital Read more…
When I moved to my new place in the beautiful canton of Valais – I did not re-activate my old Turntable and Amplifier and just left them in a corner. Today I decided to reactivate my devices again but to my disappointment I could hear only some scratching sounds form Read more…
