I started to look into the topic of Text to Speach Synthesis (TTS) on Microcontrollers with the final goal to compare different engines. Since I don’t want to be bothered to connect the Microcontroller to any output device, I decided to just render the result to a Webbrowser with an Read more…
I was wondering what the easiest way would be to provide sound generated on a ESP32 to a Web Browser: I got distracted when I googled the topic “music streaming” and everything suddenly turned out to be very complicated. So I got back to my original idea: Just change the Read more…
Today I had a look under the hood of the Standard Arduino implementation for the Raspberry Pico. I was surprised that they did not base their work on the Pico API but they based their work on ARM Mbed. Here is a blink example using the Ticker from the Mbed Read more…
I took the chance to look at the guts of one of my favorite projects: Mozzi. The major starting point is MozziGuts. Just tried to understand what code is relevant and my head started spinning… There is even an expression for this: #ifdef Hell. To make things more comprehensive, I Read more…
Im my last couple of Blogs, I have demonstrated how we can use the low level API of my Arduino Audio Tools library. Currently I am busy working on a high level API using Arduino Streams. I did not commit my latest changes yet but I want to take the Read more…

In this Blog I am giving a little bit of background on how the sampling of analog signals has been implemented in my Arduino audo-tools library. My initial approach was based on the Blog from Ivan Voras using timers and interrupts. But there is a much better way by using Read more…
Please note that a lot has changed since I published this Blog! Tought it might be possible to make this work again, you are advised to use the current API with this updated example! The processing of files with the help of the ESP8266Audio is a little bit more involved. Read more…
In my Arduino ESP32-A2DP library I am providing some very simple examples that show how to transform the ESP32 into a A2DP source and transmit sound to a Bluetooth Sink (e.g. some Bluetooth Speakers). I had quite a few questions on how to do this with files, microphones and I2S Read more…
