ABSTRACT:
A single chip, single or dual message multilevel analog signal recording and playback system is described. In one embodiment, the system comprises a record circuit, an analog storage array, a playback circuit, and a control circuit that independently controls signal storage segments and duration capability. The record circuit receives an audio signal and generates a filtered signal, which is stored in the analog storage array. The playback circuit is coupled to the storage array for retrieving the stored signal for playback. The system further includes a mixer circuit which receives an auxiliary signal and mixes the auxiliary signal with the stored signal during playback. The control circuit also features a novel audio, visual, and input/output functionality.
