OK...have my F873 and a ISD chip onboard (such it can be to the piclist with the PIC on board?) I'm recording some sound snippets from the PC, just using the mic input to the ISD. listening to the sound from the speakers on the PC, it sounds pretty clean. But, when the ISD records it and I play it back, it sounds 'noisy' for lack of a better word. Now I know its not going to be stereo quality, but perhaps its the input circuit that needs attention. I've simply followed the app notes on the input to the chip and tried an audio transformer and capacitor coupling but nothing seems to help alot. Anyone else had some experiance with the ISD chips? I've just like to make the audio sound a little cleaner. _________________________________________________________________ Add photos to your e-mail with MSN 8.
