How to convert sound samples to be usable with GEM SOUND by Lee W. Benjamin (based on an original from OUTRIDER ) OUTRIDER: We've been doing a lot of discussion on GEM Sound in the ST RT BBS. There is no program yet, that I'm aware of, for converting sounds to GEM Sound format. However, Mike Allen came up with a hack, and I've modified it somewhat. Here is the hack I've been using to convert my sounds L.W.BENJAMIN: I've taken Terry's procedure and adapted it to my own set of tools. NOTE: If your sound is already in signed format at 12.5 KHz, skip to #4. 1. Load your sound into Sound Lab, making sure Sound Lab is configured with the proper sample rate for your sound. 2. Convert the sample rate to 12.5 KHz. 3. Save the sample with a .SAM extender (saves it in signed format). Note the size and convert it to HEX. For a file 12800 bytes long, this converts to 3200 HEX. 4. If you don't have a GSHEADER.HEX file, start up EDHAK in the TEXT/HAK mode, select INSERT BYTES and press the HEX button. Enter the digits: 7E 81 7E 81 00 04 00 00. Save this file as GSHEADER.HEX 5. Load the sample file (.SAM) into EDHAK. 6. With the cursor on the first byte of the file, select the open MERGE option and select the file GSHEADER.HEX. It will be inserted into the buffer in front of the sample. 7. Enter your hex number in the 4 bytes following those inserted above. The first 12 bytes in my example would be: 7E 81 7E 81 00 04 00 00 00 00 32 00. 8. Save the file, rename it with a .SMP extender, and put it into your SAMPLES folder. 9. You now have a new sample compatible with GEM Sound! The advantage of this method over other method Terry devised is that you don't have to overwrite the first 12 bytes of the sample as you would with a sector editor. EDHAK is now a commercial product, but some of the older shareware versions were capable of these same manipulations. Take Care, Lee B. ----------
