Quite some time ago I have purchased an Audio Analog to Digital Converter (ADC) module, but I never managed to have it working properly. Unfortunately Google Search could not help either and I was the only one using this module or having problems. The Software Finally I have it working Read more
I am trying to build an Arduino based Guitar Pedal with the help of a Microcontroller and some cheap standard modules. So far, I had the data input, the Audio Effects ready and just needed to put everything together. When I tried to demonstrate how to output the sound from Read more
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
