joerg d9efa3143a full resolution for I2S input, all 32 bits are read and converted to float (instead of only upper 16 bit)
3 years ago
joerg 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.
3 years ago
joerg fa6885d4ff I2S output was sending 32 bits already, but only 16 were used. Now, send all available precision.
