The Data Footprint of Digital Audio: Compression
Wallace Jackson · Apress eBooks · 2015
People’s ears can’t perceive the same quality differences in digital audio that their eyes can perceive in digital images. There are two important “sweet spots” for digital audio support across hardware devices that you should target. A lower-quality audio (narration track or sound effects) use an 8 kHz or an 11.25 kHz sampling rate, with 8-bit, 12-bit, or 16-bit sample resolution. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
