Minimal D3D11 sprite renderer

Minimal D3D11 sprite renderer: basic back-to-front sprite rendering reference code with example sprite sheet animation logic. As usual: Complete, runnable single-function app. No modern C++ / OOP / obscuring cruft.

Swap out the sprite sheet with a font atlas for a lightweight GUI / text renderer. Clip individual sprites and glyphs by offsetting screenPos and atlasPos to top left corner of visible area and adjusting size accordingly (all values in pixels):

sprite.screenPos.x += 17;
sprite.screenPos.y += 10;

How to handle asymmetry of WAV data?

WAV files can store PCM audio (WAVE_FORMAT_PCM). The WAV file format specification says:

The data format and maximum and minimums values for PCM waveform samples of various sizes are as follows:

Sample Size	Data Format	Maximum Value	Minimum Value
One to eight bits	Unsigned integer	255 (0xFF)	0
Nine or more bits	Signed integer i	Largest positive value of i	Most negative value of i
