Signature tuning filters

A client device for providing information to an audio output device, said client device comprising:

• an input for accepting audio filter settings and audio data,
• a programmable processor, and
• an output,
• where said programmable processor is programmed to:
• receive audio filter settings in the client device;
• receive audio data in the client device;
• and
• provide said audio filter settings and said audio data from said client device to said output,
• where said output is connected to an audio output device separate from and in communication with the client device, and where said audio output device is configured for modifying said audio data according to the audio filter settings to generate a continuous audio output.

An audio output device for producing filtered time-varying audio signals, said audio output device comprising:

• an input for accepting a time-varying signal including encoded audio filter settings and a time-varying audio signal, wherein said time-varying signal is in binary format and said time-varying signal includes two types of sine waves, one of said sine waves is formed based upon a value of 1 present in said binary format and another of said sine waves is formed based upon a value of 0 present in said binary format;
• decoding electronics adapted to accept and decode said encoded audio filter settings;
• a digital signal processor to accept said audio filter settings from said decoding electronics and filter said time-varying audio signal to produce a filtered audio signal;
• and
• an output to provide said filtered audio signal.
