For the best headphone listening experience, the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. In addition to being able to decode all major formats, VS1053 is capable of recording in Ogg Vobis file. With a software patch, it’ll even play lossless FLAC audio as well.

The VS1053 shield board is even better – it combines MicroSD card storage (up to 32GB) and also takes advantage of the VS1053’s audio recording capabilities (16-bit WAV/PCM or Ogg Vorbis via patch) through a built-in microphone or your own via the 3.5mm mic input. Delving into the specs further shows the chip can drive a standard 32-ohm headphone load. Total harmonic distortion (THD) is a reasonable 0.05% at that load and signal-to-noise ratio (SNR) at full-scale is 94dB – not earth-shattering, but still very respectable.

With the TF card slot on the other side of the board, you can play mp3 files from TF card using this breakout. It is easily to drop it in your project or make a mp3 player using your Arduino or other microcontroller.

How it works

Look at the block diagram and the heart of the VS1053 is a DSP – digital signal processor – with its own RAM, control inputs, stereo analog-to-digital converter (ADC) for recording, stereo digital-to-analog converter (DAC) for playback and built-in headphone driver.

All we need is to write code that gets our Arduino board to act as traffic controller and transfer audio data from the MicroSD card to the VS1053 chip and playing out through the headphone socket (the outer of the two).

However, there is one drawback with that headphone socket – and it’s a bit technical – so the short version is the chip’s output has a DC offset, which means you can’t plug it straight into an audio amplifier. If you do, the VS1053 chip will likely blow up. However, the solution is to use a number of DC-blocking capacitors. The addendum PDF shows you the circuit required.Otherwise, we recommend you stick to headphones only and power it with a USB battery power pack (for safety, don’t use a USB wall charger). Power draw is about 80mA, so you should get a genuine full day’s playback from a 2200mAh USB power pack.

VS1053 IC

VS1053 is a versatile "MP3 decoder chip" belonging to VLSI Solution's extensive slave audio processor family. In addition to being able to decode all the most common audio formats - including the advanced features of newer AAC files - functionality of this IC can be greatly expanded just by loading a bit of extra software to its RAM memory. In addition to being able to decode all major audio formats, VS1053 is capable of recording in three different audio formats, from lossless 16-bit PCM to highly compressed, yet high-quality Ogg Vorbis files. For the best headphone listening experience the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. This option can naturally be turned off when required. All in all, VS1053 is an easy-to-use, powerful workhorse for audio playback and recording applications.

Wiring

Step by Step instruction

1.  You can use Micro SD card(<=2G) or Mirco SDHC card (<=32G) with this module.
   Most SD cards work right out of the box, but it's possible you have one that was used in a computer or camera and it cannot be read by the SD library. Formatting the card will create a file system that the Arduino can read and write to. It's not desirable to format SD cards frequently, as it shortens their life span. You’ll need a SD card reader or micro SD card adapter and computer to format your card. The library supports the FAT16 and FAT32 filesystems, but use FAT16 when possible. See additional info here.
   Format the SD card as FAT16 or FAT32. Insert the SD card in your computer. Go to My Computer and right click on the SD card. 
   You can use Micro SD card with this module only.

Library

• All libraries attached on the begining of the project description
• SdFat library. Download, unzip  and add to libraries in our PC, for example C:\Users\toshiba\Documents\Arduino\libraries. This link you can find in Preferences of Adruino IDE program which installed in your PC. You can read about it here.  The SdFat library takes care of initialising the link between the Arduino microcontroller chip and the MicroSD card, setting its speed (4MHz). The library only supports FAT filesystem, so make sure you format the MicroSD card to FAT32 before using it here.
• SFEMP3Shield library. Download, unzip  and add to libraries in our PC, for example C:\Users\toshiba\Documents\Arduino\libraries. This link you can find in Preferences of Adruino IDE program which installed in your PC. You can read about it here. 
• The SFEMP3Shield library handles most of the goodies inside the VS1053 chip. By the look of it, it doesn’t do everything (recording, for instance, seems to be missing), but there are still plenty of toys to play with, including support for VU meters, graphic equalisation, even changing the speed of playback. Much like the Arduino’s ATMEGA328P microcontroller chip, the VS1053 is programmed using a series of registers, each housing a number of controls or ‘bits’ that can either be read from or written to, controlling the various functions inside. The SFEMP3Shield library provides us with the shortcuts to coding those individual register bits, allowing us to use more recognisable ‘plain-English’ statements in our Arduino code.
• SPI library included in Arduino IDE.
• Bounce2 library. Download, unzip  and add to libraries in our PC, for example C:\Users\toshiba\Documents\Arduino\libraries. This link you can find in Preferences of Adruino IDE program which installed in your PC. You can read about it here.
