Roman Black Sound (btc)

[Ioannis]

Darrel, have a look at the attached files. It might help on the audio compression project.

Please rename the files to *.rar and then de-compress them.

Hi Ioannis,

What are they?

Roman's btc convertor creates the smallest sound files I've ever seen.
Can't imagine more compression being able to do anything without ruining the sound.

I don't use RAR.
Not brave enough to download free programs from a couple of brothers in Russia.

Hi Darrel. This is an article from the EDN magazine, February 1999. I thought to save you from the trouble to search the site and download it.

It uses the PIC16C556/12C672 and ADPCM DECODER/ENCODER techniques.

I don't know if they produce smaller files than Romans as I have not tested yet.

OK, i will try to zip it and break it into 2 files. I hope windows ZIP can do that.

I made the files *png. Hope that are readable.

Hi,
How do you convert the .BTC file generated by Romans BTC Sound encoder to a hex file?
Just done a quick search on here and using google, could not find anything that helped.....Found a HEX editor, going to see if I can encode some sound!!

Probably this is not the correct way but rename the .btc to .bin and try again... It works with WinPic800..

Hi Sirvo,
Thanks for the reply will try that, I am using the pickit2 programmer to down load the hex file. I can now down load to the eeprom, not sure if the code is right but its a start. I will keep trying.

Did you get your code working ok?
