Microphone enhancement device
First Claim
1. A microphone enhancing device for incorporation in a line from a transducer which converts audio sound into an electric signal, the device comprising:
- means for dividing the electric signal into a low band signal and a high band signal;
a signal processor for detecting a signal level above a threshold level and for reducing the magnitude of the low band signal irrespective of any reduction in the magnitude of the high band signal; and
a mixer for recombining the low band signal and the high band signal to produce a microphone output signal wherein bass proximity effect is reduced.

Abstract
A microphone enhancing device combines an automatic gain control, a band-limited compressor, and a gate in one very compact package that is small enough and efficient enough to plug into or be wired into the base of almost any microphone. A connector is provided on the device for removably connecting an infrared sensor directed parallel to the microphone. For gooseneck microphones the infrared sensor is also on a gooseneck. Low frequency tones are attenuated irrespective of attenuation of higher tones when a present audio level indicates that a speaker is too close to the microphone; this reduces proximity effect produced by microphones.

10. A microphone enhancing device for incorporation in a line from a transducer supported by a first flexible gooseneck on a support and which converts audio sound into an electric audio signal, the device comprising:
-
an infrared transducer for converting infrared light into an electric infrared signal;
a second flexible gooseneck supporting and connecting the infrared transducer to the support; and
muting means responsive to the electric infrared signal indicating the absence of a person adjacent the infrared transducer for muting the electric audio signal. - View Dependent Claims (11, 12, 13, 14, 15)

16. A microphone enhancing device for being plugged in series between a microphone and a cable, the device comprising:
-
an elongated housing;
first and second connectors on opposite ends of the elongated housing for connecting the device at one end to the microphone and at the other end to the cable;
an infrared sensor mounted on a third connector;
a fourth connector mounted on the housing for mating with the third connector so that the infrared sensor is directed parallel to the microphone; and
muting means in the housing connected to the first, second and fourth connectors for responding to a signal from the infrared sensor indicating the presence of a person adjacent the microphone for passing audio signals from the first connector to the second connector and for responding to the signal from the infrared sensor indicating the absence of a person adjacent the microphone for muting audio signals from the first connector to the second connector. - View Dependent Claims (17, 18)
