  • 4fe37d5d95 Added float modules for 24 bit precision S/PDIF I/O. They are forked from current code of the "offical" (16 bit 44.1kHz only) Teensy audio library, but extended to 24 bit precision and configurable sample rate. joerg 2022-05-15 11:55:33 +0200
  • fa6885d4ff I2S output was sending 32 bits already, but only 16 were used. Now, send all available precision. Basically, I re-did jcj83429's pull request, which got outdated, to current code: https://github.com/chipaudette/OpenAudio_ArduinoLibrary/pull/8 joerg 2022-05-15 11:50:27 +0200
