PIC Microcontoller Audio Input / Output

• PIC Microcontoller Memory Method Big Table lookups (sound playback example)
• Pink noise generator in a PIC
• Wave to data table converter
• Novel method of generating a sinewave without a lookup table. Code is in the old Parallax/SX menomics, but those are easily translated to MPASM. +
• PIC DSP / filters
• PIC PWM

Questions:

• STOPspamhellojoseph1 at SPAMyahoo.com asks:

  what i'm writing now is for asking u that i wanna add a voice message to my controller
  so i donot know how...
  ... i do not know even the name of this additional
  memory..is it normal flash (eeprom)..or there is another somthing dedicated 4 analog record
  decated 4 the audio storage.....
  +if it is normal digital eeprom like 24LC16..then how can i download an audio
  file to it..i mean will it be wav or mp3 or.....
  then after record it on the chip will i nead DAC then will i need
  an amplifier ..can u tell me about... i do not know if ur career is just plc or
  related to microcontroller too
  
  +the chip i have is pic16f877...it is 40 dip..but i can get any one u suggest..
  
  any tips ,details! , even links ,chips numbers, pdf documents. etc any thing will
  be great 4m u...
  tip:(links to buy books r not permitted!)

• Rachid Mensah asks: " Can we record voice on microship and play it back upon certain even using pic programming?" +

Comments:

• Yes, it is possible to record audio on a PIC, look here+
