Introduction In one of my last blogs I made a small test-sketch to print some audio data from an ADS1015 Analog to Digital Converter (ADC) capturing the input from an electric guitar using the Arduino loop(). In real life however, we want to drive the capturing of the samples with Read more…
Introduction I was playing with the thought of building some Arduino Based Guitar Effects Pedals. With that in mind, I have added some simple sound effects to my Arduino Audio Tools Library and this is fitting quite nicely into the overall design. Overall Design SineWaveGenerator<int16_t> sine; GeneratedSoundStream<int16_t> stream(sine); AudioEffectStream effects(stream); Read more…
In the last Blogs I presented – A File Based Versatile MP3 Player – A Streaming MP3 Player – A Streaming AAC Player with Volume Control All these examples were using my Arduino Audio Tools Library. In this final Blog about this topic, I will demonstrate how easy it is Read more…
Lately I noticed that some examples in my Arduino Audio Tools library are not compiling any more. This is not a surprise, since the library is still evolving. So I was looking for a way how to identify the broken examples automatically. Fortunately Arduino provides a Command Line Interface and Read more…
In the last Blogs I presented a File Based Versatile MP3 Player and later a A Versatile but Simple Arduino Streaming MP3 Player using my Arduino Audio Tools Library. In this Blog, I will demonstrate how easy it is to convert it into a AAC player. I also show how Read more…
In the last blogs I presented a Versatile MP3 Player and then a Basic Streaming MP3 Player using my Arduino Audio Tools Library. If you expect a Versatile Streaming MP3 Player, you will not be disappointed. All the functionality related to the AudioPlayer class which was described in the Versatile Read more…
Yesterday I was finally resolving some stability issues in my URLStream class and I wanted to take the opportunity to highlight that it is pretty simple to build a simple mp3 streaming audio player using the Stream API of my Arduino Audio Tools library. You just need to copy the Read more…
It is pretty simple to build a simple mp3 audio player using the Stream API of my Arduino Audio Tools library: A SD file is a subclass of an Arduino Stream, so all you need to do is to copy from the file to the desired output stream. when we Read more…
Today I was testing my Arduino Audio Tools project with PlatformIO on an ESP32 because I was really looking forward to be able to use a proper Debugger. Unfortunately I was stumbling over the fact that, while Arduino is using now the latest IDF version, the PlatformIO ESP32 Arduino implementation Read more…
Quite some time ago I was blogging about the hw-627 motor controller. So I was wondering if I could also use this module as well to play music and drive a small speaker. This would be cool because we could get stereo output since the module supports two output devices. Read more…
