hi,

i have a audio pictail daughter board and an explorer 16 board. i have successfully played the speex speech encode decode wideband demo. the demo has an encoded wav file, .s file, that is written to the program memory, decoded in the program then sent to the wm8510 codec to be played. i was wondering if i can work around this and send files directly to the codec to be played.

do you think it is possible? and if it is, what files can the wm8510 play, can it play .wav files, .mp3 files? any help is appreciated.

thanks

Hi

Yes you can!, but some file type need to be decoded first - like MP3

Basically the 8510 accept raw data (non condensed & non encoded ) and convert them to sound

All the best

Re: audio pictail wm8510

that's great! so i can just use wav files and it will work? i plan on playing wav files broken down to several files; like instead of 1 full audio sound, i will cut it down and send 5 wav files one after another. can the 8510 handle that or would there be problems? thanks

Hi

Remember to strip down the wave file before playing them - remove unnecessary data like "file header" etc

Re: audio pictail wm8510
