Yes, another one of these. I wanted to test some file with more interesting audio data, and of course, LEGO Island has a lot of that.

The majority of audio from LEGO Island is PCM 16-bit mono 11.025Hz, with some at 8-bit mono 22.050Hz. I just rendered this one in the former, that's way the video is much longer.

Some of the audio is interleaved with data, that's why there is some crackle and jumps on otherwise clear audio. More details here:

Video input parameters: -f rawvideo -pixel_format rgb32 -video_size 32x32 -framerate "11025/2048"
Audio input parameters: -f s16le -ar 11025 -ac 1
Upscaled to 4k for better bitrate on YouTube.

Formula for the framerate: audio rate / (width x height x (color depth / audio bitdepth)).
In this case: 11025 / (32 x 32 x (32 / 16)) = 11025 / 2048 = 5,3833...
It's better to use formulas so that ffmpeg handles decimals better.
