I have extended the I2S interface in Mozzi, so that we can can use the getAudioInput() which reads the audio via I2S: This can be used e.g. by the AudioKit. Until this change has been merged, you need to use my extended project. Mozzi brings your Arduino to life by Read more…
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. The AudioKit is a cheap ESP32 based audio board that usually Read more…
The goal of this blog is to give a quick introduction into using TensorFlow Lite For Microcontrollers to create Audio Output with the help of the audio-tools library. Hallo World The starting point is the good overview provided by the “Hallo World” example of Tensorflow Lite which describes how to Read more…
The staring point for doing speech recognition on an Arduino based board is TensorFlow Light For Microcontrollers with the example sketch called micro_speech! I have presented a DRAFT proposal for a Micro Speach API in one of my last posts. In the meantime I have finally managed to adapt the Read more…
The staring point for doing speech recognition on an Arduino based board is TensorFlow Light For Microcontrollers with the example sketch called micro_speech! There are quite a few alternative Arduino Libraries for TensorFlow Light but honestly the situation is rather dire and I could not find any version which would Read more…
Last year I was digging into Arduino Based TTS Solutions and came to the conclusion that the available engines will not provide any quality audio and therefore recommended to consider an approach which is based on recorded audio samples. Today I took the opportunity to create the new arduino-simple-tts project 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…
For quite some time I was wondering why my arduino-fdk-aac library was using so much memory for the encoding of AAC files. Now that I have an AudioKit working with the debugger it was easier to analyze the situation and – oh boy – I found quite some errors. So Read more…
I was planning to use the PlatformIO Debugger for quite some time: Here is a good overview of how to get started. I can also recommend Low-cost ESP32 In-circuit Debugging from Manuel BL. I wanted to use it both with OS/X and Linux: Most tutorials however describe Windows and therefore Read more…
After using the AI Thinker AudioKit I wanted to make sure that my libraries also work with the ESP32 LyraT Board from Espressif. There were basically just 2 stumbling blocks: Deploying Code: From the AudioKit I was used that I can plug in the UART cable and upload the code Read more…
