mixing

1. 1
   verb

   Present participle of mix.

   The DJ is mixing two tracks into one seamless set.

   Mixing red and yellow paint produces a bright orange.

   Note

   The -ing form does two jobs. After be it makes the progressive (he is mixing the paint), and as a gerund it fills a noun slot while still taking a direct object (mixing paint is messy). That object is the test that separates it from the noun for a mixture, which takes of and can be plural, as in mixings. Studio uses carry over unchanged: mixing tracks, mixing a recording.

2. 2
   noununcountable

   The act of making a mixture, or the combination that results from it.

   Thorough mixing of the cement and sand gives a stronger mortar.

   The final mixing on the album gave each instrument its own space.

   Note

   Uncountable when it names the process (thorough mixing gives a stronger mortar), it turns countable when each batch or session is treated as a separate result: no two mixings of these paints are ever the same. The plural mixings signals that distinct outcomes are being compared rather than one ongoing activity, and it is worth reaching for when the batches themselves differ.

3. 3
   adjective

   Of a stochastic process, having distant parts that become asymptotically independent, so values far apart in time carry almost no statistical relationship.

   The chain is mixing, so samples drawn far apart are effectively independent.

   A mixing sequence loses memory of its initial conditions over time.

   Note

   A statistician's adjective for processes and chains, used both after be (the chain is mixing) and before a noun (a mixing sequence). It often travels with stationarity: a strictly stationary, mixing process with finite expectation obeys a law of large numbers. The term covers a family of conditions, distinguished by prefixes such as α-mixing and β-mixing. Each one formalizes how dependence fades as the time lag grows.
