1. An apparatus that is configured for dynamic normalization to reduce loss in:

  • precision for low-level signals, comprising;

    a processor;

    memory in electronic communication with the processor; and

    instructions stored in the memory, the instructions being executable to;

    determine a normalization factor for a current frame of a signal, wherein the normalization factor depends on an amplitude of the current frame of the signal, and wherein the normalization factor also depends on values of states after one or more operations were performed on a previous frame of a normalized signal;

    normalize the current frame of the signal based on the normalization factor that is determined; and

    adjust the states'"'"' normalization factor based on the normalization factor that is determined.
