Description: Speech Signal Acquisition and Analysis
Simply put, you can stream at the original voices superimposed delayed for some time after the acoustic streaming, achieve echo effects. Of course, through complex calculations, can calculate a variety of reverb effects. Echo so produced, we call the digital echo. Initialization, configuration: 05 through 12C bus to configure the command sent to the AIC23, configured to work after the completion of AIC23. Speech Signal input: AIC23 through one of the AO Acquisition conversion of voice input signal, a signal after each acquisition, the data is sent to the 05 interface on McBS households, 05 can be read into the voice data, each data is 16 bit unsigned integer, a value about each channel. Voice signal output: 05 may be voice data sent through the interface McBS families give AIC23, AIC23 of OA devices into their analog signal output.
