High-resolution audio, with quality mics.
We record sound in high resolution, with quality mics, at a wide frequency range 20Hz-50kHz. We use 24-bit and 96KHz when mastering. The interest is to keep the best of the sound, and to be able to reproduce it with high quality, for 4K screens, showrooms, and trade shows.
This quality will be compressed by a video-sharing platform (Youtube, Vimeo, Instagram, Facebook, etc.). The bitrates are reduced to 320Kbps and the sampling rate to 48Khz. This compression is a necessary evil for playback to be possible on the Internet.
