As part of our product line, we use ISD4003-05MPY chips to record music and sound effects into six different areas of memory. As the part number implies, it holds 5 minutes of audio and takes quite some time to record dozens of chips as needed. Does anyone have an idea how to record multiple chips at one time? If you parallel the chips, they will record but the sound gets distorted. I am guessing the internal oscillators are interfering with each other. The parallel method works when programming PIC microcontrollers but not these ISD Chips. Thank you.
