The audio layer works slightly differently. This includes important items for the mission, and also additional items like security systems, and anything that might contain information. You will be able to scan items, just like in hacker mode, to get information on them. The visual layer is the most obvious, as it encompasses everything you see. For example, a datapad might need to be switched on for you to be able to interact with it, and this portion of the Braindance will be highlighted. Even if a scene contains clues, you can only interact with those closes if you find them within the scene in these segments. When there is something important to find, the timeline will have a slightly fatter section on it. Yellow is visual, green is audio, and blue is thermal.Īs you watch through the Braindance on any of the layers, stick close to the person who actually recorded the scene. In the editor, you can hit the “switch layer” button (it will be detailed in the bottom right of the screen, along with all the other controls for the Editor) to jump between these three layers. This will give you a good idea of where the characters go in the scene, and what it is actually about. There is a timeline at the top of the player, and it is usually a good idea to watch through the whole Braindance before you jump into the editor itself. The recording is split into three layers, Visual, Audio, and Thermal. In the world of Cyberpunk, they are used as a form of entertainment, but for V they can lead to valuable clues and information during certain missions in the game.īraindance is all about paying attention to detail, and the Braindance Editor gives you all the options you need to get to the bottom of whatever mystery you are investigation. The conditions for this relationship are that the sound propagation process is adiabatic and that the gas obeys the ideal gas law.Braindance in Cyberpunk 2077 is basically looking through the recorded experience of another person for clues. Using the ideal gas law PV = nRT leads to So that the derivative of pressure P with respect to volume V can be taken. The bulk modulus can therefore be reformulated by making use of the adiabatic condition in the form The adiabatic assumption for sound waves just means that the compressions associated with the sound wave happen so quickly that there is no opportunity for heat transfer in or out of the volume of air. When a sound travels through an ideal gas, the rapid compressions and expansions associated with the longitudinal wave can reasonably be expected to be adiabatic and therefore the pressure and volume obey the relationship The speed of sound for a uniform medium is determined by its elastic property ( bulk modulus) and its density So the detailed modeling of the effect of water vapor on the speed of sound would have to settle on an appropriate value of γ to use. However, the assumption of an adiabatic constant of γ = 1.4 used in the calculation is based upon the diatomic molecules N 2 and O 2 and does not apply to water molecules. A revised average molecular weight could be calculated based on the vapor pressure of water in the air. The calculation above was done for dry air, and moisture content in the air would be expected to increase the speed of sound slightly because the molecular weight of water vapor is 18 compared to 28.95 for dry air. This leads to a commonly used approximate formula for the sound speed in air:įor temperatures near room temperature, the speed of sound in air can be calculated from this convenient approximate relationship, but the more general relationship is needed for calculations in helium or other gases. 004 kg/mol, so its speed of sound at the same temperature isĭoing this calculation for air at 0☌ gives v sound = 331.39 m/s and at 1☌ gives v sound = 332.00 m/s. For the specific example of dry air at 20☌, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu.įor helium, γ = 5/3 and the molecular mass is. It is interesting to compare this speed with the speed of molecules as a result of their thermal energy. The speed of sound is v sound = m/s = ft/s = mi/hr. γ = the adiabatic constant, characteristic of the specific gasįor air, the adiabatic constant γ = 1.4 and the average molecular mass for dry air is 28.95 gm/mol.M = the molecular weight of the gas in kg/mol.R = the universal gas constant = 8.314 J/mol K,.The speed of sound in an ideal gas is given by the relationship
