KTL=KuulutustenTekoLaite (Announcement Producing Machine). I forgot to mention that the chip had a bug in recording ADPCM. You may need to add 127 (or 128, cannot remember anymore) to the values in order to produce clear sound. This may have been fixed in PC driver automatically - I don't know.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5096278891763426276.post-43982449990719267642014-06-17T15:29:28.608+03:002014-06-17T15:29:28.608+03:00Greetings from the original sound driver coder. Th...Greetings from the original sound driver coder. The onboard unit is (or was?) a Transputer based proprietary hardware designed and manufactured by Rauma Oceanics Oy (yes, the same company that designed and manufactured the submarine shown in Titanic). The sound chip was Crystal Semiconductor CS4231. The announcements were produced using Crystal's development ISA card mounted on a PC running NeXTstep 3.1. I wrote both the Transputer driver and the NeXTstep driver for the chip. As you guessed right, there's a separate routing info which connects GPS points to the announcements + train schedules. This way the system was able to drop out connecting train announcements, if the train was late for a GPS point. The routing info was stored on a PCMCIA memory card. This allowed using the same CD for all trains (330 at the time... ~1993) and schedule changes etc. were easy to update using the PCMCIA.

I too would really like to have the whole sound library as usable and clear clips, but we'll have to wait. VR, the railway company, would do a culturally significant deed if they did release the sounds in an open and compatible manner. They are, after all, built on state money (mine included) so the could very well release some left overs to the people.llaurénhttps://www.blogger.com/profile/04068903248575812756noreply@blogger.comtag:blogger.com,1999:blog-5096278891763426276.post-83790662325114130982014-06-17T00:59:08.608+03:002014-06-17T00:59:08.608+03:00Wow, this is great.
