emkay Posted July 23, 2004 Share Posted July 23, 2004 I think I found something weird... While all "Softsynth" Tunes are using 3900Hz constantly.... Blood Fighter seem to use a mixture of POKEY Voices and Samples... So in standard the SAP shows variable rates from 200 to 800Hz. Now the point of Wonders ... When Playing the high "singing voice" the IRQ Rate jumps up to 10000-15000 Hz. Is this a bug of the PLAYER? I always thought that the main voice is built by some 1,79MHz features... but it seems to be a digitizing thing? Actually SAP cannot play most of the 1,79MHz sounds, this "singing Voice" is played. So whats the riddle behind it? Is it really digitized? Quote Link to comment Share on other sites More sharing options...

Schmutzpuppe Posted July 23, 2004 Share Posted July 23, 2004 I took a quick look at it and the AUDCTL seems to be set to 6 (channel 1+2 to 16bit and channel one highpass clocked by channel 3). Anyway, the IRQ info of the sap player doesn't seem to be very accurate. It shows me 50-150hz for some song which are definitely 50Hz.

emkay Posted July 24, 2004 Author Share Posted July 24, 2004 Hm... setting bit "6" means channel one using 1,79MHz Value "6" means 2 = filter 1+3 4 = filter 2+4 ___________ 6 = all voices used for filtering (this is what you can hear off the song) Using channel 1+3 with 1,79MHz would be hex66 or dec106. It seems... someone tried to "fast" manipulate the "singing" voice and I ask myself why? Quote Link to comment Share on other sites More sharing options...
Schmutzpuppe Posted July 24, 2004 Share Posted July 24, 2004 AUDCTL is set to 6 not bit 6 but I made a mistake about the pokey behaviour. Six means highpass for channel 1 and channel 2. Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted August 3, 2004 Share Posted August 3, 2004 Well, the Bloodfighter sound is 44,1 khz - on my Audio CD of course;-) In reality it is a digitized / sampled sound. The demo version of Bloodfighter can be found at the atari demo page by Sven Gleich (thats where I got it from). There is also a demo called "Best of Liebich Demo" that contains some Bloodfighter sounds (as well as other T.Liebich sounds)... -Andreas magenheimer. P.S.: You know, I recorded 180 Atari 8Bit game sounds and 140 demo sounds to Audio-CDs (as "simulated stereo") and then converted them into two MP3 CDs... available at the ABBUC shop soon (Alas, Koronis Rift, the Eidolon, Schreckenstein and a few other well known game sounds are mising, since I do not own these games and could not find their sounds in any sound demo...)
