Internally, Mixbus uses a technique called floating-point math. This video discusses some additional thoughts about gain staging: With the increased low-level resolution of modern converters, it is not necessary to record at high levels. This indicates that the signal was far from the clipping level when it was converted to digital. With modern A/D converters, we recommend that you record your signals with the peak meter never exceeding -15 dB. Luckily with modern 20+ bit converters, this is very easy to do. So our goal is to prevent signals from clipping, but keep them well clear of and above the noise floor. But sustained clipping, when the signal is significantly outside the bounds of the “real world”, creates lots of ugly distortion that we want to avoid. Regardless of the number of voltage steps, there will be a value that indicates “maximum volume”, and if you exceed that value, then the system must “clip” the excessive values to the largest possible value.Ī very short “clip” is almost always unnoticeable (just at the peak of a snare-drum hit, for example). A 24 bit number can store signals from an infinitesimally small noise floor (lower than a very quiet studio), all the way up to a roaring jet-engine volume. Generally speaking, 16-bits worth of numbers can recreate everything between a typical quiet-room noise and a very loud sound (i.e.“CD quality sound”). If the noise floor is less than the noise in your environment, then you won’t even notice it. This technique is called Dithering, and careful use of dither is one of the reasons that Mixbus sounds great.įor our purposes, the “noise floor” of a signal is the noise level in the quietest part of the recording this might include noise that was picked up by the microphone, or dither noise that was used to cover up quantization noise inherent to digital maths. For these reasons, we must make sure there’s enough random noise to cover up any quantization noise that we’ve introduced. Quantization noise is slightly more offensive than “regular” (random) noise. This happens quite often inside the computer, where the bit depth changes depending on many factors. *Quantization noise happens whenever you represent the signal with fewer steps than you had before. Too few numbers introduces “quantization noise”. More numbers (voltage levels) represents more accuracy in the signal’s representation.
