摘要:
Enhancement of audio includes receiving a restriction parameter with audio input and determining a restricted audio input. Another audio input track is manipulated based on the restricted audio input track, and the audio tracks are combined. Conformation of audio to a musical key is also disclosed. The interval between two notes of the audio input are determined and a note corresponding to the second of the note is selected based on a musical key and the interval. Intervals between each note pair of the audio input are summed and each note is scored. A best-match note is selected. The second note of the audio input is conformed into the frequency of the best-match note. Creation of harmonizing tracks includes receiving audio input and harmonizing tracks are created. Each of the harmonizing tracks are transposed. Individual notes are manipulated based on a chord strictness threshold and audio output is provided.

A system is disclosed for transmitting alternating current power and communication signals between a first location and a second location via a communication path which includes at least one inductive load (5) and at least one switching means (13) for switching power to said at least one load on and off. The system includes control means (25) adapted for controlling said at least one switching means so that, in response to switching off said power, a direct current is applied to said at least one inductive load and, in response to actuation of said at least one switching means to switch said power on, said power is switched on during a phase of the power which results in a magnetisation of said at least one inductive load opposite to that resulting from said direct current.
