Sound playback options

Sound playback options

2010-10-10 by Philippe Habib

I'm working on a project that requires several minutes of good quality sound
playback.  The ideal thing would be to control an Ipod or similar player.  A
device that can store up to about 12 sound clips of up to about a minute
each is what's desired.  The sound quality desired is about Ipod level so a
lot of the cheap and easy sound chips are ruled out on that basis.

 

Quantity is very low, so cost isn't a huge issue.  Under $100 would be fine.

 

Does anyone have any ideas for how to deliver this?

hi dear philippe
for the first way you can simply use any VLSI chips to play your files ( or record perhaps ), its very simple & cheap way to solve this problem, this chips already used in portable media players & can handle mp3, wma, wav, midi, oog vorbis ...etc files.
you can use many source codes ( c or basic ) for this purpose by search in internet
 
the second way is little harder & cheaper than first, you can use sd or mmc card for store your sound files & use every avr chips with enough ram ( such as mega 64 ) & convert your file to lookup & then play With PWM output, 
 
if you are not pro in codewrinting i suggest you to use first Way. 
 
besT wishes.

I use a Vmusic module that plays MP3 with a custom board
we make which includes a 20W amplifier.

Thank you.  That vmusic thing looks like a nice way to add features without
too much work.  After not finding what I wanted, I stumbled into just what I
was hoping for.  For only $10, I'll get one and play with it.

Here's the one I ran into.

Thank you for the response.  I wound up finding a $10 player that takes an
SD card and uses serial commands to play back any track on demand.  Since I
only need a very low number of these, this is a better solution than
anything that requires work on my part.
