Abstract: The audio processing device and method provided in the present disclosure include an audio processing device that includes a sound-producing module and an audio processing circuit. The sound-producing module includes K sound-producing units, each with different audio characteristics, where K is an integer greater than one. After obtaining the initial audio data, the audio processing circuit converts the initial audio data into K-channel target audio data, with each channel's target audio data adapted to the audio characteristics of the corresponding sound-producing unit. The K-channel target audio data is then input into the corresponding K sound-producing units, where each sound-producing unit converts the corresponding target audio data into the target audio, thereby forming reverberated sound. This approach enhances the audio quality of the audio processing.

Abstract: Immunoassays useful for distinguishing between the insect pests Heliothis virescens and Helicoverpa zea are disclosed. These immunoassays employ either Heliothis virescens-specific monoclonal antibodies which do not detectably cross-react with tissue of Helicoverpa zea, or Helicoverpa zea-specific antibodies which do not detectably cross-reict with tissue of Heliothis virescens. Thus, use of these antibodies in immunoassays conclusively demonstrates the presence of either Heliothis virescens or Helicoverpa zea organisms on crop plants tested. Also disclosed are Heliothis virescens-specific monoclonal antibody which does not detectably cross-react with tissue of Helicoverpa zea, and Helicoverpa zea-specific monoclonal antibody which does not detectably cross-react with tissue of Heliothis virescens. These antibodies can be used in the disclosed immunoassays, and can be included in kits for conducting the disclosed immunoassays.
