Samples for <Flut>:
*******************
16bit-8000Hz.wav    21.02.2020  Lara  not used. Must be 44.1ksS
16bit-44100Hz.was   21.02.2020  Lara  2-periods
              = Flut_Wave_Lookup.inc
                used as Wave10 in the firmware
flut_4p.wav         02.03.2020 Lara  4-periods
              = Flut_4p.inc    has waveform irregularity
                used as Wave11 in the firmware
C_flut_4p_8000Hz16bit_2.wav   09.03.2020   Lara
C_flut_4p_44100Hz16bit.wav    09.03.2020   Lara  4-periods
              This sample is derived from low C (60) on the flute. 
              = Flut_4p11.wav (copy)
              = Flut_4p11.inc replaced as data for wave11 in the PIC
flut_out_achter.wav           09.03.2020
              output wave as recorded with excitement wave Flut_4p11.inc
flut_out_boven.wav           09.03.2020
              output wave as recorded with excitement wave Flut_4p11.inc
flut_out_voor.wav           09.03.2020
              output wave as recorded with excitement wave Flut_4p11.inc
              This wave was used to calculate the excitation wave.
              The data are in Flut_Excit_Front.inc
              This is the data set now used on flut for the notes 60-71
