I endedp up recording a duck quack sound using Audacity. I then exported the quack to a (Microsoft) 16 bit signed PCM 89KB .wav file and a 10KB .mp3 file and saved them to my computer. My current design I am using a small Microchip 8 bit microcontroller with six IO pins and I am sounding a magnetic buzzer with a square wave as an alert. I'd like to change this where I store the .wav file (or one of the other 11 exporting file types) in eeprom and output the file to a DAC and to a speaker when I want the alert sound. My dilemma: 1. What is the best/easiest file type to convert the quack to. 2. How to get the .wav file (or other file type) from my hard drive into the eeprom. 3. What type of cheap DAC chip to use (not familiar with them at all). Any suggestions are welcome. Thanks! --000e0ce0d3baa63a3e04bf6103bd Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable
