It is designed for applica- tions on talking back with an echo effect. Func- tions of the IC consist of recording/playing and auto power off in addition to an echo effect. The IC starts recording when a sound input is de- tected, and stops to play back when silence lasts 0.5 seconds during recording. The auto power off function is activated once a REC/PLAY cycle has been implemented 64 times or an interval of silence exceeds 2 minutes. The HT8665 provides a recording capacity of 2 seconds at a 32K bps sampling rate for DRAM of 64K (8 seconds for DRAM of 256K) and 4 seconds at a 16K bps sampling rate (16 seconds for DRAM of 256Kb). A higher sampling rate results in sounds of better quality but sacrifices the recording time, and vice versa. 1 21st Dec ’95 |
