In APR9600, you may record maximum of 60 seconds and playit back with different settings through the Buttons connected. So i suggested you to connect those buttons of the APR9600 to the pins/port of the 8051 which is programmmed in the way you need it to swicth. Thaz it. Refer the datasheet of the device for all the application circuits. Now dont ask me to design and post a complete project with schematics, code and PCB.
Cheers
