2 Hours of 4K/HD 1kHz Reference Tone

A reference tone is a pure tone corresponding to a known frequency, and produced at a stable sound pressure level (volume), usually by specialized equipment for facilitating measurements and for aligning gains and losses of a system. The most common reference tone in audio engineering is a 1000 Hz tone. It is meant to be used by audio engineers in order to adjust the playback equipment so that the accompanying media is at a comfortable volume for the audience. In video production, this tone is usually accompanied by a test card so the video programming may be calibrated as well. 2 hours Audio Bit Depth - 24 bit Audio Sample Rate - 96kHz Audio Bit Rate - 512kbps Audio Channels - 2 stereo Sony AVC AAC MP4 0-30 minutes -12dB 30-60 minutes -6dB 60-90 minutes -3dB 90-110 minutes -1.5dB 110-120 minutes -0dB
