Voice Recorder Chip
Voice recorder chip has excellent noise reduction technology, which can effectively filter out noise and ensure interference-free recording. It is widely used in various products such as recordable greeting cards, telephone exchanges, recording machine movements, security equipment and toys.
Voice Recorder Chips
By using either the MIC or line-in method, audio files can be recorded into the chip, enabling on-site recording functionality. Currently available series include WT588F, WTR, WT2003H, and WT2605. Recording durations range from 1 minute to 3 months. Additionally, certain sounds can be pre-stored in the chip, ensuring they remain fixed and cannot be deleted or overwritten, for use as product alert tones.

Frequently Asked Questions
WTR096, WT2003H, and WT2605 are all sound chips that support high-quality recording.
1. You can check whether the correct playback command has been sent by sending the code. 2. If it is an external Flash project, check if the Flash is soldered properly.
Supports up to 10 recording segments. If you need more recording segments, please contact our business for consultation. The chip has a built-in 132KB Flash that can store voice and can record for 90 seconds at an 8K sampling rate; Support external installation of 2-128Mb Flash, capable of recording for more seconds.
The chip itself supports storing fixed voice and recording, and supports BIN modification using our upper computer.
Compared to ISDN1820, due to the differential input of ISD1820’s microphone, the recording quality is higher than WTR096, but correspondingly, the cost is also higher than WTR096.
Support, just configure the recording parameters on the upper computer.
Mainly consider from two aspects. 1. Is the bin file configuration for chip burning reasonable and can be adjusted on the upper computer according to the actual situation; 2. Check the hardware PCB circuit, whether the wiring is reasonable, whether it has been adjusted by high-frequency interference devices, mic recording circuit, and whether there is power interference.
Waytronic’s recording chips all support automatic recording overlay.
Both WTR096 and WT2605 are acceptable, depending on your specific needs.
Based on the current demand for recording chips in pet feeders, WTR096 is generally sufficient.
