Abstract: An exemplary compounding method of controlling a compounding device to prepare an admixture of at least two distinct material sources can include examining material source solutions for incompatibility of the ingredients and operating a first and a second pump to prevent one of the incompatible source solutions from entering a common flow path. The processing method can detect degradation of a fluid line by evaluating one or more of calibration error rate data, cumulative volumetric flow data, or cumulative pump operation data. The processing method can also selectively transfer a first group of source solutions using the first pump, receiving pump data from one or more sensors that sense actions of the pumps, applying fluid correction factors and calculating discrete pump movements, the pump movements being indicative of an amount of source solution displacement by a pump, and operating the pumps to selectively dispense the source solution amounts according to a preparation order.

Abstract: A library of audio segments of a song is generated by receiving recorded tracks that include a complete performance of or a composition of unique portions and repetitive portions of the song, segmenting a select track into intervals, analyzing each interval to characterize the interval, comparing each interval with subsequent intervals of the select track to identify repetitive content in the song, identifying a select interval from a set of repeated intervals from the select track and storing the encoded representation of each of the select intervals from a corresponding set of repeated intervals in the library. Intervals can be characterized by frequency analysis, cross-correlation of a waveform, by a trained ear or by analysis of a musical notation corresponding to the song. Intervals for compression can be based on beats, that is, the time for a designated note, notes, a measure, or multiple measures. One or more unique measures can be encoded for additional compression.
