Workflow of a MP3 player based on PIC

[scorrpeio]

Hello,

I have to build a mp3 player... This is what I think is cost effective...


1. Burn the music files in SD card
2. Use PIC(16 series probably) to fetch the files through SPI
3. Connect Audio amplifier IC to the PIC
4. Send the music file to the audio amplifier.
5. Connect two small speakers to amplifier.

Please let me know, if this sequence is flawless.
I need a right direction to work on this project. Please share your views.

Re: MP3 Player using PIC

You'd want to use an MP3 decoder. I doubt the PIC16 is powerful enough to decode the data and play it properly quickly enough. You could use something like a STA013: MP3 Player, How To Use The STA013 MP3 Decoder Chip

Hope this helps.

Dear Scorpeio
Inaddition to MP3 Decoder, You have forgot the Audio DAC too.
You should have an sterio Audio DAC like AD1852 | Stereo, 24-Bit, 192KHz, Multibit Sigma Delta DAC | Audio D/A Converters | Audio/Video Products | Analog Devices to convert audio frames obtained from MP3 decoder to sterio analog audio which can estimulate the analog speakers.

I have a lot of experience in MP3 Decoder Designing.
Feel free to ask your questions.
Hope this helps.
