Hi All,
I’m facing a new challenge that I haven’t tried to solve before and I would like some input if anyone has tried this before. I need to record and playback voice/sound from a microphone and store it on a Secure Digital card with FAT16 file format, which is no problem, but what I would like some input on is what “front end” IC I could use to maybe do the MP3 encoding so that I only have to “cheat” and store the pre encoded signal on the SD card and be able to play it back again.
I was thinking of using maybe a IC like this: http://www.analog.com/UploadedFiles/Data_Sheets/76229755AD73311L_a.pdf although it does not have the capacity to encode/decode MP3, I could use it for both encoding and decoding my raw audio signal, but what I can’t determine is if I’m able to store the data as fast as it samples with 64/32KHz onto the SD card.
I know that Micronas makes some kind of MAS de/encoder for MP3 but have anyone had success with it?
Best regards
Lasse Madsen
