Choose mp3 Player Chip

The MP3 player chips are audio chips that decode the MP3 file on the memory and play the sound.

MP3 is a lossy compression format. If the MP3 player has an excellent decoding chip, it can better restore the quality of the audio signal.

The working principle of MP3 player chip:

  1. First, the MP3 file is stored in the memory (flash media, hard disk media, optical disc media), and the signal decoding chip on the memory is read to decode the signal.
  2. Convert the solved digital signal into an analog signal through a digital-to-analog converter
  3. Amplify the converted analog audio
  4. Output as music after low-pass filtering

The Mp3 chip is favored by the market because of its high compression ratio and excellent sound quality. It is widely used in players, broadcasting systems, security reminders, smart homes, multimedia, and many other fields.

The WT2003H series of MP3 chips play an important role in Waytronic products. The WT2003H series uses a high-performance 32-bit processor with a maximum frequency of 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility.

The control method is flexible: Support standard serial communication (UART), with file index playback, inter-play, single cycle, all track cycle, 32-level volume adjustment, random playback, etc.

If you need to use a TF card as storage, you can choose WT2003H4-16S TF card version, if the memory is SPI flash, you can refer to the FLASH version of WT2003H4-16S, which can support external 128Mbit Flash.

Of course, they can also exist at the same time. In addition, the powerful WT2003HP8-32N has 8M bit built-in Flash, super small package size, is the best choice for high-end audio products.

In addition, the WT2605 series also supports MP3 decoding, not only playback but also MP3 recording, Bluetooth audio broadcast, and other functions. You can refer to the WT2605B03 module program.
