Bindings for the Wasapi API on Windows

# Wasapi bindings for Rust


The aim of this crate is to provide easy and safe access to the Wasapi API for audio playback and capture. 

The presented API is all safe Rust, but structs and functions closely follow the original Windows API. 

For details on how to use Wasapi, please see [the Windows documentation](https://docs.microsoft.com/en-us/windows/win32/coreaudio/core-audio-interfaces).

Bindings are generated automatically using the [windows](https://crates.io/crates/windows) crate.

## Supported functionality


These things have been implemented so far:

- Audio playback and capture
- Shared and exclusive modes
- Event-driven and polled buffering
- Loopback capture
- Notifications for volume change, device disconnect etc

## Included examples


| Example                    | Description                                                                                            |
| -------------------------- | ------------------------------------------------------------------------------------------------------ |
| `playsine`                 | Plays a sine wave in shared mode on the default output device.                                         |
| `playsine_events`          | Similar to `playsine` but also listens to notifications.                                               |
| `playsine_poll`            | Similar to `playsine` but uses polling instead of event driven timing mode.                            |
| `playnoise_exclusive`      | Plays white noise in exclusive mode on the default output device. Shows how to handle HRESULT errors.  |
| `playnoise_exclusive_poll` | Similar to `playnoise_exclusive` but uses polling instead of event driven timing mode.                 |
| `loopback`                 | Shows how to simultaneously capture and render sound, with separate threads for capture and render.    |
| `record`                   | Records audio from the default device, and saves the raw samples to a file.                            |
| `devices`                  | Lists all available audio devices and displays the default devices.                                    |
| `record_application`       | Records audio from a single application, and saves the raw samples to a file.                          |
| `aec`                      | Captures audio with Acoustic Echo Cancellation (AEC) enabled and saves the raw data to a file.         |
