Abstract
Some embodiments of the invention are directed to an audio production system which is more portable, less expensive, faster to set up, and simpler and easier to use than conventional audio production tools. An audio production system implemented in accordance with some embodiments of the invention may therefore be more accessible to the typical user, and easier and more enjoyable to use, than conventional audio production tools.
Claims72
A method for use with an audio system comprising at least one amplifier, the method comprising acts of:
- (A) receiving, at the audio system, audio input produced by at least one audio source;
- (B) determining a gain level associated with the audio input;
- (C) automatically, without intervention by a user of the audio system, adjusting a gain level of the at least one amplifier, so that subsequent output of the at least one amplifier falls within a dynamic range delimited by a lower gain level and an upper gain level;
- wherein the method comprises, after the act (B), receiving a second audio input while the audio source is not producing sound, and the act (C) comprises determining the lower gain level of the dynamic range based at least in part on a gain level of the second audio input.

A method for use with an audio system comprising at least one amplifier, the method comprising acts of:
- (A) receiving, at the audio system, audio input produced by at least one audio source;
- (B) determining a gain level associated with the audio input;
- (C) automatically, without intervention by a user of the audio system, adjusting a gain level of the at least one amplifier, so that subsequent output of the at least one amplifier falls within a dynamic range delimited by a lower gain level and an upper gain level;
- wherein the act (B) comprises:
- determining a peak gain level associated with the received audio input;
- determining the upper gain level of the dynamic range based at least in part on the peak gain level;
- and
- defining the upper gain level of the dynamic range so that a first difference in gain level, between the upper gain level and the peak gain level, is 30% or less of a second difference in gain level, between the upper gain level and the lower gain level of the dynamic range.

- and
- wherein the act (A) comprises identifying the at least one musical instrument as a guitar, voice, bass or drum, and the act (C) comprises setting the gain level of the at least one amplifier to be a different gain level if the at least one musical instrument were identified as a guitar or voice than if the at least one musical instrument were identified as a bass or drum.
