Mozzi brings your Arduino to life by allowing it to produce much more complex and interesting growls, sweeps and chorusing atmospherics. These sounds can be quickly and easily constructed from familiar synthesis units like oscillators, delays, filters and envelopes. One of the strong points of my AudioTools library is, that Read more…
Quite some time ago I have identified Maximilian as interesting tool which can be used to implement synthezisers. Maximilian is a cross-platform and multi-target audio synthesis and signal processing library. So I was wondering if it is possible to use it on Arduino based Microcontrollers. In the meantime the adapted Read more…
In this Blog I would like to look into the options how we can connect a microcontroller with a Midi Keyboard. MIDI is a communication protocol from the 1980s that connects musical instruments and computers. MIDI keyboards nowadays usually have USB support and offer a separate MIDI port. Some modern Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. I didn’t do much with my Arduino STK project lately, so I think this is the perfect opportunity Read more…
In the last Blog, I have shown how to use the Synthesizer class. I wanted to verify the audio quality issue by sending the output to Bluetooth Here is the sketch. I just added a callback method to feed the bluetooth source: Arduino Sketch #define USE_MIDI #include “BluetoothA2DPSource.h” #include “AudioTools.h” Read more…
I have described in my last blog how to build a simple Synthesizer with my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. In the meantime I have decided to wrap the described solution into it’s own Synthesizer class Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. In my Arduino Audio Tools we have all ingredients to turn our ESP32 AudioKit into a simple synthesizer 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…
