Offler Posted June 13, 2011 Share Posted June 13, 2011 Ok lets talk about the sound hardware I used:Soundblaster LIVE 5.1 (with SPDIF digital CD IN)And/orSoundblaster X-fi Fatality (extreme music)ATA DVD rom Samsung with SPDIF-CD OoutBose speakersSoftware:Windows 98SE + KEX + Windows media player 9WDM drivers for Soundblaster (they work by some miracle)Direct X 9.0 with Directsoundand/orWindows 7 Ultimate x64WDM drivers 32 bitDirect X 11 without Directsound (removed since vista)OpenAL, ALchemyWindows media player 11 (+-)Getting work SPDIF input on Win98 was a hard nut. No other software except WMP 9 was able to run it. But when it was done, and WMP has been tuned up to use digital-CD-IN the sound was very very good. to re-test it i have run program which consumed up the CPU, but the sound was still perfect. Therefore I believe that sound is processed via soundcard without any direct need of CPU. (hardware accelerated). But here the first and last degradation occurs. SB Live outputs sound natively in 48KHz while CD format is 44 KHz.New system, new hardware... But no SPDIF input for standard digital CD input. Still possibility to connect it via SPDIF IN but only via jack, not PIN. Until i construct that cable the sound must be "grabbed" and transported via ATA cable. Sound quality from CD has been here downgraded for the first time. there is not direct sound - therefore there is no pure hardware acceleration. When CPU is involved another sound stuttering might occur during high load of system. At all the card is able to output sound in 44KhzStill the older system has one less possible degradation... If I will be able to connect the DVD drive directly to the SPDIF it might help to improve sound quality. But is there any software able to play from SPDIF? Will see.But for me its strange to know that 10 years hardware has better sound as the new one. Link to comment Share on other sites More sharing options...
