Required because it seems everyone has invented their own filesystem on the Arduino with their own unique twist. See the examples directory for some simple examples, but the following snippet can play an MP3 file over the simulated I2S DAC:įile = new AudioFileSourceSPIFFS( "/jamonit.mp3 ") ĪudioFileSource: Base class which implements a very simple read-only "file" interface. Either break large delays into very small ones with calls to AudioGenerator::loop(), or reduce the sampling rate to require fewer samples per second. Since this is not interrupt driven, if you have large delay()s in your code, you may end up with hiccups in playback. This will automatically read as much of the file as needed and fill up the I2S buffers and immediately return.
Mp3 library software serial#
Tools->lwIP Variant->v1.4 Open Source, or V2 Higher BandwidthĬreate an AudioInputXXX source pointing to your input file, an AudioOutputXXX sink as either an I2S, I2S-sw-DAC, or as a "SerialWAV" which simply writes a WAV file to the Serial port which can be dumped to a file on your development system, and an AudioGeneratorXXX to actually take that input and decode it and send to the output.Īfter creation, you need to call the AudioGeneratorXXX::loop() routine from inside your own main loop() one or more times.

Install the library in your ~/Arduino/libraries You can use GIT to pull right from GitHub: see this README for detailed instructions. Source and instructions for a gorgeous wooden MP3-playing clock, FM radio and a walkie-talkie using the ESP8266 and AVR microcontrollers is available Prerequisitesįirst, make sure you are running the 2.6.3/later or GIT head version of the Arduino libraries for ESP8266, or the latest ESP32 SDK from Espressif.
JohannesMTC has built a similar project especially for model trains: Ī neat MQTT-driven ESP8266 light-and-sound device (alarm? toy? who can say!) was built by available at Ī very interesting "linear clock" with a stepper motor, NTP time keeping, and configurable recorded chimes with schematics, 3D printer plans, and source code, is now available More info is available here, including STL files for 3D printed components! Detailed discussion on the process and models are included.Įrich Heinemann has developed a Stomper (instrument for playing samples in real-time during a live stage performance) that you can find more info about here.ĭagnall53 has integrated this into a really neat MQTT based model train controller to add sounds to his set. Harald Sattler has built a neat German word clock with MP3 alarm. My personal use of the ESP8266Audio library is only to drive a 3D-printed, network-time-setting alarm clock for my kids which can play an MP3 instead of a bell to wake them up, called Psychoclock. If you have a neat use for this library, I'd love to hear about it! Neat Things People Have Done With ESP8266Audio
PRs to rewrite it to be less memory intensive would be much appreciated. NOTE Opus decoding currently only works on the ESP32 due to the large memory requirements of opusfile. Opus, OGG, and OpusFile are from with the Xiph license and patent described in src//COPYING. MIDI decoding comes from a highly ported MIDITONES combined with a massively memory-optimized TinySoundFont, see the respective source files for more information. The ESP8266, however, does not support it due to a lack of onboard RAM. On the ESP32, AAC-SBR is supported (many webradio stations use this to reduce bandwidth even further). For commercial use you're still going to need the usual AAC licensing from Via Licensing.

The AAC decode code is from the Helix project and licensed under RealNetwork's RSPL license.

The software I2S delta-sigma 32x oversampling DAC was my own creation, and sounds quite good if I do say so myself.
Mp3 library software mod#
The MOD and MP3 routines were taken from StellaPlayer and libMAD respectively. If you find any bugs, please let me know via the GitHub issue tracker or drop me an email. DisclaimerĪll this code is released under the GPL, and all of it is to be used at your own risk. ESP8266Audio - supports ESP8266 & ESP32 & Raspberry Pi RP2040Īrduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x oversampling.ĮSP8266 is fully supported and most mature, but ESP32 is also mostly there with built-in DAC as well as external ones.įor real-time, autonomous speech synthesis, check out ESP8266SAM, a library which uses this one and a port of an ancient format-based synthesis program to allow your ESP8266 to talk with low memory and no network required.
