In my last Blogs I looked at SAM and Arduino/TTS. I was putting high hopes in CMU Flite: CMU Flite (festival-lite) is a small, fast run-time open source text to speech synthesis engine developed at CMU and primarily designed for small embedded machines and/or large servers. Flite is designed as Read more…
In my last Blog I looked at SAM. Now it is time to look at jscrane/TTS. TTS is a popular Text-to-Speech Library for Arduino which is supporting many different Microcontroller Architectures. I was extending the project, so that I could receive the data as stream: My extended project can be Read more…
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 Blog I have demonstrated how we can use some simple Sound Generator with my Arduino Audio Tools library. I spent a small effort to integrate Mozzi and the result looks quite promising. Mozzi brings your Arduino to life by allowing it to produce much more complex and 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…
