I decided to use my SAM TTS Library with the AI Thinker Audio Kit. Unfortunately I found quite some bugs in my library that I needed to correct first, but now it is working as expected. Here is the Arduino Sketch #include “sam_arduino.h” #include “AudioTools.h” #include “AudioLibs/AudioKit.h” AudioKitStream kit; SAM 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…
In my last blog, I have described how to process audio input data and encountered the bug that the microphone and line input are mixed together and that there is an open issue for this which has been open for quite some time now. So I decided to do a 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. The AI Thinker ESP32 AudioKit was raising my interest because it also provides audio input in the form Read more…
Arduino AudioKit HAL 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. . There are different ESP32 AudioKit boards available that can be programmed with the Espressif 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. . Originally I was of the opinion that the program logic for reading of the GPIO pins and 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 thought it might be helpful to have a ‘Text to Speech’ example for the Audio Kit. Read more…
