How to build a small circuit that can play digital music files? Answered

I want to build a small circuit that can play and pause a single digital music file. I haven't been able to find any useful resources online so far. Can anyone point me in the right direction? I have very little knowledge in the area, but am very keen to learn! Thanks :)

That's a tricky one - I think these ideas won't be suitable.

A sound recorder module - Records 20 seconds of audio at pretty awful quality.

The MP3 modules discussed HERE - Overkill for the purpose and too complicated if you've no prior electronics experience.

A TalkBotBrain would appear closest to what you're after.  It allows you to convert .WAV files to its format and play them back at the touch of a button.

If the music file is just a .wav or equivalent (un-compressed) at a suitable data rate, this is fairly easy for a microcontroller to do; there are Arduino-based solutions, for example.

If you want to handle MP3, that's more complicated; I haven't checked what's available.

Your going to have to spend some money to build a controlled MP3 player or modify a CD player or tape deck to do the job.

is a solution - at a price.
