 *** Special Note ***  6 January 2021- This library is undergoing revision to make Teensy 4.x compatible and to add functionality.  The Tympan Library
 files and associated classes output_i2s_f32.h, output_i2s_f32.cpp, input_i2s_f32.h, input_i2s_f32.cpp are now
-ready to be used for T3.x and T4.x.  There are some restrictions, particularly this should be used with 16-bit I2S codec data. Notes and details are at the bottom of this page.  Work on the F32 i/o routines is continuing.
