Audio Analyser, Converter and Recoder |

Lumelang,
Using a 18x452, I want to build an audio analyser/recoder/encoder that will be able to handle balanced pair input (Audio1[Left and Right] and Audio2[Left and Right]).
The aquired audio data should be in a form that can be analysed by whatever logical algorithm for valid interpretation analysis purposes, and or the audio data could be encoded to maybe a .WAV or an .MP3 format for instance.
1. Where do I start on this project?
2. Is there a microcontrollable chip in the market that can analyse or encoder?
3. What sampling logic should I apply, when it comes to the AUDIO spectrum?
Thank you in advance,
Hatanet |

Look at the dsPICs instead. |

Thanks, but where do i startcoz dsPic is a bit foreign to me at the moment... I have the development board now! |

Start searching at the place where you acquired your development board, and ofcourse there are the forums at the microchip website http://forum.microchip.com/
Ever heard of Google???? |

If you REALLY want to use CCS you could probably do one channel of audio in a PIC. So you just need four PICs, all running the same code, and a fifth to play traffic cop and handle user interface. That will be a lot easier than handling four audio streams and user interface in one chip. _________________ The search for better is endless. Instead simply find very good and get the job done. |
