Reference Designs

• The VS1053b USB Hi-Fi Player is a multi-format "MP3 player" that uses the VS1053 as a stand-alone component along with a low-cost High Speed (480 Mbit/s) USB controller. The device can play .MP3, .OGG, .AAC, .M4A, .WMA, .WAV, .IMA and .MID files with excellent sound quality. It can either use SD/SDHC cards (over 2 GB supported) or internal FLASH memory.
• The HiFi Recorder Application demonstrates the capabilities of VS1000d and VS1053b chips for high quality stereo recording from line-in or microphone interface.
• VS1003 SD Card Mini Player application is an extremely simple SD card player. It features mp3 and WMA audio formats, small size, excellent audio quality. It is likely the simplest, smallest and lowest cost SD card player in the world.
• The VoIP Speaker Phone application demonstrates the use of VS1003 for echo cancellation in the USB speaker phone. In addition of being best echo cancellation for Skype kind of speaker phone, the system has nice features such as conversation recorder, SD card audio player and USB mass storage memory that are valuable for a traveler.
• VS1000 Button Cell Player application is a very low power audio player. It features Ogg Vorbis decoding with very low bit rates and credit card size. The low BOM of less than 3 USD and royalty free audio compression make it attractive for disposable audio applications such as audio guide of a museum or marketing gift.
• VS1000 Audio Book application demonstrates VS1000 device capabilities in portable bible or audio book application. The system features excellent audio quality, high audio compression. The smart indexing with bookmarking is capable to handle thousands of predefined jumps and endless loops.

Evaluation Boards
