voice recording module/sound module/voice chip
Elements of FBelec Musical Instruments:
The cost of the same kind of Voice Module Sound Chip is directly proportional to the size of the Recordable Sound Chip.
a) The allocation of I / O ports and the size of ROM (voice seconds) determine the chip cost;
b) Sound quality is improved, sampling is improved, and speech seconds are shortened;
The sound quality decreases, the sampling decreases, and the speech seconds become longer;
c) Calculation method of speech seconds: M / (n * f)
M --- ROM size (bit) n * f --- baud rate

Recording template parameters(Recordable Talking Sound Module Voice Chip)
1. The recording module supports mic and line recording;
2. It can support plug-in 64M bit spi-flash at most, and the recording time can reach 1600 seconds;
3. Support uploading and downloading voice via USB;
4. Support the playback of high quality voice downloaded by the computer;
5. Up to 252 segments of voice (including fixed voice) can be recorded;
6. Support the function of saving data after power failure;
7. Support 10kHz sampling rate recording and 14k sampling rate recording;
8. An independent file management system is adopted, no fragments are generated in the recording, and the spi-flash space is allocated more reasonably;
9. Support button and MCU control;
10.10 level controllable volume;
11. Working voltage DC3 3V。
12. Adopt 8-bit DSP core recording chip, 16 bit ADC input and 16 bit DAC output;
13. Support plug-in spi-flash, with capacity ranging from 4m bit to 64M bit;
14. support the first mock exam, one button to one mode and three wire serial port control mode.
15. Support line line recording and Mic field recording;
16. You can set the sampling rate by yourself and support 6K to 16K sampling;
17. The voltage range is DC2 7V to 3.6V, with low voltage detection circuit;
18. The power saving mode only consumes less than 150ua;
19. It can be widely used in telephone recording, industrial control, consumption, toys and other fields.
