Instant Voice ROMs, IVRs, are specialty devices for storing and playing sound. IVRs utilize the company's EPROM technology together with sound synthesis and D/A technology to make instant sound storing and playing possible. The ISSI IVR products contain an EPROM, ADPCM sound decoder, and an A/D circuit. Users first prepare an 8bit PCM sound file and then use the ISSI IVR development system to do the ADPCM encoding. The encoded data is programmed into a IVR device by using our IVR writer. This application note discusses the IVRs in detail.
