What is the difference between .apng and .voc?

Description: Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files.; The VOC file format is an audio file format primarily used by Creative Technology's Sound Blaster sound cards for storing digital audio data. Developed by Creative Labs, the VOC format was widely used for storing sound samples and music files on PCs during the late 1980s and early 1990s. VOC files support mono and stereo sounds at various sampling rates and can contain multiple sound snippets and silence segments, making them versatile for a range of audio applications, including video games, sound effects, and voice.
