Here is a shield for Arduino 328's that solves this problem. It can play up to 22KHz 12bit uncompressed audio files of any length.\u003c\/p\u003e\n\u003cp\u003eIt's low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD\/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.\u003c\/p\u003e\n\u003cp\u003eThis shield is a kit, and comes with all parts you need to build it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eArduino, SD card, tools, speaker and headphones are not included.\u003c\/strong\u003e It is fairly easy to construct and anyone with a successful soldering project under their belt should be able to build it.\u003c\/p\u003e\n\u003cp\u003eThe shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when serial data is received, etc. Audio is played \u003cem\u003easynchronously\u003c\/em\u003e as an interrupt, so the Arduino can perform tasks while the audio is playing.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCan play any uncompressed 22KHz 16bit (on a 12bit DAC), mono Wave (.wav) files of any size. While it isnt CD quality, it is certainly good enough to play music, have spoken word, or audio effects. \u003ca href=\"http:\/\/learn.adafruit.com\/adafruit-wave-shield-audio-shield-for-arduino\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck out the demo video\/audio at the webpage\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eOutput is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker that is switched on when the headphones are unplugged\u003c\/li\u003e\n\u003cli\u003eFiles are read off of a FAT16\/FAT32-formatted SD\/MMC card\u003ca href=\"http:\/\/learn.adafruit.com\/adafruit-wave-shield-audio-shield-for-arduino\/sd-card\"\u003e \u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncluded library and examples makes playing audio easy\u003c\/li\u003e\n\u003cli\u003ePlease note that the library \u003cem\u003eis\u003c\/em\u003e rather bulky, requiring 10K of flash and more than 1\/2 K of RAM for buffering audio.
