In conferences, important places, or important evidence conversations, products such as recording pens are often used. In addition, there are also products such as recording toys and recording boxes. The reason why they can record is that the mainboard has a built-in recording chip. Let POROSVOC tell you about the main differences between the recording chip and the playback chip in which aspects!

So what is a recording chip? How is it different from a sound chip?

First of all, voice chips can be divided into recording voice chips and playback voice chips from the functional APP. The main difference is that one has a recording function, and the other has no recording function, but both have a sound function.

Recording toys, recording pens, recording boxes and other products require recording functions, and the development of such products uses recording chips. The recording module developed by the recording chip has simpler peripheral circuits and better sound quality. In addition, since the recording module uses an external FLASH ROM as the storage center, it can record longer sounds, and can also insert TF card and USB memory to exchange sounds. There are also many products that use the sound function, such as sound toys, musical greeting cards, story machines, sound alarms, alarm clocks, clocks, and mobile phones. Such a product does not need to record the sound of the scene and only needs to download the processed sound to the sound chip for playback.

When designing a product using a sound chip, first consider whether to record the sound of the scene. If you need to record the sound, choose a sound chip with a recording function, otherwise choose a sound chip with only a sound function. Generally, a sound chip with a recording function has the function of playing sound, but when playing sound, there is no playing sound chip specifically for sound quality, so it is necessary to balance functions and sound quality when selecting a sound chip.

NR7100S has three modes: key control mode, parallel control mode, and two-wire serial control mode, which can be easily used on various occasions and is a cost-effective standardized recording and playback module.
