Hi,

I want to build Portable audio player which can play wave files from
MMC (MultiMedia Card).The interfacing part of microcontroller and MMC
is done. I am stuck with playing part.The application I made which
reads from MMC and out it on microcontroller's PORT parallelly at 8khz
since my wave file is sampled at 8khz.

Here is the problem part. I want to build DAC and audio filter.Can
anyone suggest me any Ic which can be used as DAC and filter as well as
amplifier or any two of these. Currently I am using simple R-2R
ladder,RC filter and LM386 as amplifier.But in my case audio sound is
very noisy.Can someone help me?

Thanks and regards,
Gaurav Sarode.
