My extensions are focused in these areas: **Floating Point Audio Processing**: The Teensy Audio Library processes the audio data as fixed-point Int16 values. While very fast for the Teensy 3.0-3.2, it is unnecessarily constraining (IMO) for the Teensy 3.5 and 3.6, which both have floating-point units. To enable floating-point audio processing, I have created: -* **AudioStream_F3288: Following the model of Teensy's `AudioStream` class. In addition to the new `AudioStream_F32`, this file includes a new `audio_block_f32_t` in place of `audio_block_t`, as well as a new `AudioConnection_F32` in place of `AudioConnection`. -* **New Audio Processing Blocks**: Using this new floating-point capability, I've written some new audio processing blocks that operate using floating-point audio values instead of fixed-point values. As I'm just starting to build these blocks, I've only got `AudioEffectGain_F32` right now. More will be added over time. +* **AudioStream_F32: Following the model of Teensy's `AudioStream` class.

Examples include `AudioEffectGain_F32` and `AudioEffectComperessor_F32`. +* **F32 Versions of Existing Blocks**: To maintain continuity with the Teensy Audio Library, a number of the Audio Library's Audio blocks (which process as Int16 data) to operate on floating-point (ie, Float32) data. Thanks to other people's contributions, examples include `AudioMixer4_F32` and `AudioMultiply_F32`. Feel free to convert more blocks, if you'd like! * **New Hardware Controls**: The Teensy Audio Library does a great job of wrapping up the complicated control of hardware elements (such as the SGTL5000 audio codec) into a nice easy-to-use classes. But, sometimes, certain features of the hardware were not exposed in those classes. Here, I've extended the default classes to expose the extra features that I want. See `AudioControlSGTL5000_Extended` as an example. After installing this library into your Arduino->Libraries direction, you can have access to any of these capabilities simply by including the following command in your Arduino sketch: `#include `.
