Пытаюсь повторить проект https://habr.com/ru/company/skillfactory/blog/542858/

Скачал код библиотеки с гитхаба https://github.com/sensorium/Mozzi

код программы https://github.com/techno-womble/Audiophonic-Workbench/blob/main/APW-Sketch.ino

//  AudioPhonic WorkBench Sketch. 
// 
//  Simulate three vintage style test oscillators
//  with amplitude and frequency cross modulation
//
//   *************************************** IMPORTANT ***********************************************
//
//   This sketch requires mozzi_config.h to be
//   be changed from STANDARD mode to HIFI.
//
//   In mozzi_config.h,
//   change
//       //#define AUDIO_MODE STANDARD
//       #define AUDIO_MODE STANDARD_PLUS
//       //#define AUDIO_MODE HIFI
//   to
//       //#define AUDIO_MODE STANDARD
//       //#define AUDIO_MODE STANDARD_PLUS
//       #define AUDIO_MODE HIFI

скетч перестает компилироваться и вываливается куча ошибок

Ошибка компиляции для платы Arduino Pro or Pro Mini.

может кто нибудь у себя закомпилить, и/или подсказать где ошибка кроется. поиск на форуме библиотеки не дал результата

А с какой целью в библиотечный код вносились изменения?

автор проекта, да и описание библиотеки содержит сведения, что возможно увеличить качество звука, для этого нужно одно раскомментировать другое закоментировать

AUDIO_MODE holds the audio mode setting.
Select STANDARD (deprecated), STANDARD_PLUS or HIFI audio output mode in the Mozzi/mozzi_config.h file with
\#define AUDIO_MODE STANDARD_PLUS or \#define AUDIO_MODE HIFI.
In Mozzi/config.h, comment one of these options in and the others out to set the audio mode.

In STANDARD_PLUS mode the sample resolution is 488,
which provides some headroom above the 8 bit table resolution currently used by
the oscillators. You can look at utility/TimerOne library for more info about how
interrupt rate and pwm resolution relate.

HIFI audio mode enables much higher quality output by combining signals from pins 9 and 10.
For HIFI mode, edit Mozzi/mozzi_config.h to contain \#define AUDIO_MODE HIFI,
and comment out \#define AUDIO_MODE STANDARD and \#define AUDIO_MODE STANDARD_PLUS.

@note Teensy 3.* plays 12 bit audio in STANDARD or STANDARD_PLUS modes, and has no HIFI mode.

//#define AUDIO_MODE STANDARD

Ну, в принципе, логично: если звук по качеству ниже всякой критики, то существенно улучшить его можно, полностью отключив.

Посмотрел я на список файлов библиотеки, их возраст составляет от 6 лет до менее месяца, т.е. библиотека интенсивно модифицируется. Вполне вероятно, та версия, что скачана Вами, сильно отличается от версии, скачанной techno-womble (автором скетча) .

Кстати, загляните к автору:

1. Он, похоже, отвечает на заданные вопросы (последний ответ 5 дней назад).

2. Вопрос относительно некомпилируемости библиотеки после изменений ему уже задали (правда, он еще не успел на него ответить).

тут дело однозначно в библиотеке, в коде скетча можно все строки закомментировать кроме вызова библиотеки и все равно ошибки сыпит

Разве с этим кто-то спорит?
