Compressor system with EQ
View Patent ↗The utility model provides a compressor system with an equalizer (EQ). The compressor system includes a signal input device in signal communication with the EQ and a compressor. The compressor system further includes a signal output device in signal communication with the compressor. The compressor includes a signal detection module. In the system, an electrical level threshold of a full-band audio signal is setup in the compressor, and the value of electrical level of the input signal is detected by the signal detection module. After comparison of electrical level threshold and the value of electrical level, the system determines whether the compressor is activated or deactivated. The system can achieve the technology effect of effectively compressing and limiting the audio signal of a different frequency.
1. A compressor system with an equalizer (EQ), the compressor system comprising:
a signal input device;
an equalizer in signal communication with the signal input device to receive a first input signal, and to generate an equalized signal based on the input signal;
a compressor in signal communication with the signal input device to receive a second input signal, the compressor including a signal detection module in signal communication with the equalizer; and
a signal output device in signal communication with the compressor to receive one of a first output signal or a second output signal, wherein the compressor includes a signal detection module to perform audio signal processing of the compressor system with EQ based on operations comprising:
outputting, via the signal input device, the first input signal and the second input signal to the compressor in parallel and at the same time, the second input signal being identical to the first input signal, and the second input signal is input to the compressor directly, while the first input signal is regulated by the equalizer to generate the equalized signal;
outputting, via the equalizer, the equalized signal to the compressor, and detecting the equalized signal via the signal detection module, wherein an electrical level threshold of a full-band audio signal is setup in the compressor; and
comparing a value of an electrical level of the equalized signal detected by the signal detection module to the electrical level threshold of corresponding frequency, in response to the value of electrical level of the equalized signal being greater than or equal to the electrical level threshold,
wherein the compressor is triggered to compress and limit the second input signal, and in response to being triggered processes the second input signal to generate the output signal and outputs the output signal to the signal output device, and
wherein, in response to the value of electrical level of the input signal being less than electrical level threshold, the compressor is not triggered to process the second input signal, generates a second output signal based on the second input signal, and outputs the second output signal to the signal output device.
