Recording Module Recording Chip Application Fields and Parameters
The application fields of recording chips are very wide, such as recording roses for gifts, teddy bears for toys, answering machines for communication, and recording pens necessary for reporters, etc.
The application in these fields is because the recording chip has the following irreplaceable advantages:
1. With long-term recording module recording chip;
2. The function of recording and playback can be repeated many times, and various functions can also be customized;
3. It has the function of setting different voice prompts according to different applications;
4. Support direct key control and single-chip serial port control;
5. The sampling rate during recording is 8KHz, and the sound quality of recording and playback is good;
6. Fixed voice support 6KHz ~ 24KHz sampling rate;
7. A variety of audio source loading methods such as microphone on-site recording, direct recording of analog signal sound with audio cable, and digital voice programming with software;
8. Use the USB port to download voice information, the transmission speed is fast;
9. Equipped with powerful upper computer operating software, the operation is simple and clear;
10. Independent fixed voice area and live recording area;
11. The fool software supports WAV, MP3, ADPCM download, and supports recording content upload;
12. Adopt low-power working mode, suitable for long-term work;
13. Up to 256 segments of voice can be recorded, and the minimum segment length is not limited by time;
14. It can record high-quality voice from 30 minutes to 16 hours (depending on the external NAND-FLASH);
Recording module chip parameters;
Working voltage: DC3.3V or DC5V.
Description: Record voice information from microphone, analog audio source, and PC software to the recording module, and send control commands (such as pulses, microcomputer data information, etc.) to the WTV-NAND recording module at the control end, and then the recording module can be triggered to play the recorded alarm. voice.
Support NAND-Flash from 16MByte to 256MByte.
Related word description
Field recording: refers to the voice recorded from the field through the microphone (the first field recording is set as a fixed voice by the system, which is convenient for on-site operation).
Live Playback: Play the live voice recorded through the microphone.
Fixed recording: use computer software to program the voice into the recording module, including alarm prompts, crowd evacuation prompts, advertising slogans, hourly timekeeping, etc.
Scope of application: The recording module is a multi-functional module that integrates recording and playback. It can collect on-site audio information in the form of sound. It is suitable for various fire alert sites and places that require high-quality long-term recording and playback, such as conferences. Recording, telephone recording, repeater, learning machine, etc.
In practical applications, if you feel that the function of the recording module is not enough, you can customize the function, and it is easy to customize the function of the recording module. For example, the card learning machine can easily record and play the content of multiple cards.
