**Special Note** 17 June 2020 - This library is undergoing revision to make Teensy 4.x compatible and to add functionality. Changes are expected throughout the rest of June. See this readme for summaries during this period. Notes:
1-synth_sine_f32.h & .cpp allowed both KINETISK and__IMXRT1062__ to support T4.x. Tested 3.6, 4.0
2-Fix synth_pinknoise_f32.h & .cpp built in I16 to F32. Now T3 and T4.
3-Fix synth_whitenoise_f32.cpp to include IMXRT1062 and built in I16 to F32. Now T3 and T4.
4-Added Gaussian White Noise F32. This is T3 and T4.
5-Renamed 3206 codec to .xxx to stop collisions with Teensy I16 library. Needs work.
6-Added new examples/SignalNoise_float.ino to test white, pink, Gaussian noise and sine. Audio out.
7-Disabled output_i2s_f32.h, .cpp by .xxxfile type. These need rework for T4. Use Convert_F32toI16.
8-Disabled control_tlv320aic3206.h, .cpp by .xxxfile type. These collide with Teensy I16 Audio.
9-Added new analyze_peak_f32.h and .cpp that parallel similar classes in the Teensy I16 library.
10-Added new analyze_rms_f32.h and .cpp that parallel similar classes in the Teensy I16 library.
11-Moved AudioSwitch_F32 from Tympan, added 8-channel version.
12-Added /examples/Switches_float.ino for 4 and 8 channel switches.
13-Moved FFT_Overlapped_F32 files from Tympan, revised for T4.0, added _OA name isolation.
14-Moved Overlapped FFT LPF .INO from Tympan to OA. Working T3.6 and T4.0
15-Moved Overlapped FFT AudioFormantShifter INO and related from Tympan to _OA Open Audio. Tested 3.6 and 4.0.
16-Moved AudioFrequencyShifter INO and related from Tympan to _OA Open Audio. Tested 3.6 and 4.0.
17-Working on SdFatWriter and related SdFat files. DO NOT USE.
18-Modified AudioEffectDelay for T4.0.
19-Moved in radio function AudioFilter90Deg_F32.
20-Moved in radio function RadioIQMixer_F32.
21-Added Example INO, FineFreqShift_OA.ino with Hilbert shifter and delay stereo.
22-Brought in support stuff mathDSP_F32 and sinTable512_F32.h.
23-Brought in AudioAnalyzePhase_F32 and Example
24-Brought in AudioFilterEqualyzer_F32 and 2 Example
25-Brought in AudioFilterFIRGeneral_F32 and 2 Example INOs
26-Brought in RadioFMDetector_F32 and Example
27-Brought in synth_sin_cos_F32 and test example
28-Brought in RadioNoiseBlanker_F32 and Example
29-Created output_i2s_OA_F32.h and .cpp to have F32 input. Work in Progress, DO NOT USE. Set to .xxx
30-Repaired Audio Mixers 4 & 8. These are adders, NOT RF DBM's---see Multiplier_F32.

**Special Note 2*** 2 July 2020 - Recently, the input and output I2S for F32 have been disabled as they had major hardware problems with
Teensy 4.x. The previous output_i2s_f32 files supported variable sample rate and variable block size, but only
