Optional Libraries

Optional Libraries

Dependent on the example you might need to install some of the following libraries:

• Many Codec Libraries which are described in the Wiki

• Communication

  • ESP32-A2DP Library to support A2DP Bluetooth Audio (for the ESP32 only!)
  • TinyHttp a http server that also supports audio for multiple users
  • TinyFTPClient A platform independent FTP client
  • arduino-snapclient An Arduino client for Snapcast

• Audio Boards

  • arduino-audio-driver Support for many audio boards and audio chips (AudioKit, Lyrat, ES8388, WM8960 etc)
  • arduino-vs1053 Support for VS1053 audio modules
  • Obsolete
    • arduino-wm8960 Support for WM8960 audio modules
    • arduino-audiokit Support for the ESP32 AudioKit and audio chips (ES8388, A1S, etc)

• MIDI

  • arduino-midi A simple MIDI message parser and generator
  • arduino-midi-fileparser A simple MIDI file parser

• I2S Libraries

  • rp2040-i2s I2S library for MBED RP2040
  • stm32f411-i2s I2S library for the stm32f411

• Audio DSP Libraries

  • arduino-stk Synthesis ToolKit in C++ (STK)
  • Maximilian cross-platform and multi-target audio synthesis and signal processing library
  • Mozzi A sound synthesis library for Arduino

• Fast Fourier Transform

  • KissFFT Fast Fourier Transform FFT Library
  • esp32-fft Another FFT library (not only for the ESP32)

• Text To Speech

  • SAM A Text to Speech Engine
  • TTS A Text to Speech Engine
  • flite A Text to Speech Engine
  • simple-tts A Simple TTS engine using prerecorded audio (e.g. to implement Talking Clock, Talking Numbers)
  • espeak-ng eSpeak NG is an open source speech synthesizer that supports more than hundred languages.

• Infrastructure

  • SdFat Library to read and write files supporting SD cards with FAT16/FAT32 and exFAT
  • freertos-addons elegant C++ API for FreeRTOS

• Synthesizer

  • YM2413 a great API for the YM2413 paired with a not so great simulator
  • Commodore 64 SID A SID emulator driven by the SIDStream or SIDPlayer classes

• Machine Learning

  • Tensorflow Lite Machine Learning for Arduino

Please note that this list does not show the supported libraries that are already part of the Arduino implementation: e.g. SD Library, Cmsis, Espressif DSP Library etc.
