Arduino Wav Player

Ryan, a SparkFun Engineer, wrote a tutorial that will guide you through using an Arduino main board, a AD5330 breakout board (8-bit DAC), and a microSD Shield to make a slick device to playback uncompressed Wav files.

Can it play more than one sound at once? In other words could I have it play background music uninterrupted but still be able to handle other sound effects like shots?

So this can't be done with one arduino?

how can i make buttons to switch songs?

I have something very similar the same I developed. I haven't figured out what the buzzing noise is (I have the same noise on my player, too). Perhaps you have a clue? There are no interrupts hooked up besides the ones I'm using and audio output is done via interrup while SD access happens. I can play 48KHz and still have cycles to spare...

that's the sleekest most compact MP3, excuse me, WAV player I've ever seen.

Hello Friends,

I am seeking knowledge to develop a project that
I have in mind.
I would like to make those cards that is inside of dolls that when activated they speak a few phrases like'' HELLO YOU WANT TO PLAY? '' Then I thought
to manufacture and put in the dolls.
But for that I have to know if Visual Basic makes this type
programming and how to do?
Thank you for your attention and look back.
Hug.

@DJMC5ive Unfortunately, it's not that. I'm using PWM output (think class D audio) with no amplification. The speaker is directly connected to the PWM output pin. If I had a scope and/or a logic analyzer I'd be better armed to find the cause, but it is not mains hum. I think there is something in the AVR repeatedly holding off interrupts for a few ms. I'll have to read the AVR datasheet cover-to-cover. Some nice bedtime reading, I think :)

I was going to do something like this for an Ambient noise generator of sorts.

needs a high pass filter to kill the cps hum
