US Patent:

7899192, Mar 1, 2011

Filed:

Feb 20, 2007

Appl. No.:

11/708452

Inventors:

J. Craig Oxford - Nashville TN, US
Patrick Taylor - Huntsville AL, US
D. Michael Shields - St. Paul MN, US

International Classification:

H03G 3/00
H03G 5/00
G10L 19/00

US Classification:

381 61, 381 98, 7042001

Abstract:

A method for dynamically adjusting the spectral content of an audio signal, which increases the harmonic content of said audio signal, said method comprising translating an encoded digital signal into data bands, creating a psychoacoustic model to identify sections of said data bands that are deficient in harmonic quality, analyzing the fundamental frequency and amplitude of said harmonically deficient data bands, creating additional higher order harmonics for said harmonically deficient data bands, adding said higher order harmonics back to said encoded digital signal to form a newly enhanced signal, inverse filtering said newly enhanced signal, and converting said inverse filtered signal to an analog waveform for consumption by the listener.

Appl. No.:

14/970357

Inventors:

J. CRAIG OXFORD - NASHVILLE TN, US
PATRICK TAYLOR - HUNTSVILLE TN, US
D. MICHAEL SHIELDS - ST. PAUL MN, US

International Classification:

H03G 9/18
H04R 3/04

Abstract:

Circuit and associated methods for dynamically adjusting the spectral content of an audio signal, which increases the harmonic content through the systematic introduction of amplitude asymmetry. In one embodiment, the method comprises a spectral modification of an analog audio signal in which the high-frequency content is reduced as a function of the signal amplitude and spectral distribution. The audio signal is subjected to a complementary pre-emphasis and de-emphasis of the high frequencies.
