first, the first choice is whether the sound source is clean, is it monophonic sound effect or diphthong and polyphonic? Or pure music? If good sound quality is required, and the positioning of the IC chip of the product's voice music is high, it is necessary to select the matrix with high seconds to improve sampling.

second, communicate with the music engineer before writing the software. For example, some products' voice music IC chips need to be loud, some products' voice music IC chips need to be crisp, and some products' voice music IC chips need to have a sense of hierarchy.

third, when writing software, you can add some silence at the beginning, middle and end of music playback to increase the three-dimensional sense.

Fourth, the rhythm should be consistent with the original sound. With the above attention, the voice music IC chip can easily meet the product requirements.

the above points are the keys to the sound quality of audio music IC chips, which is our many years' experience in making audio music IC chips. For more questions, discuss with Wei Wu of Orweiye Engineering Department. Baidu can search directly. Or QQ:584588853
