PUBLIC COMMENTS Java Sound plays 10% too fast. Two independent problems were identified: 1) On a specific Windows 2000 machine, it happens with DirectAudio lines. This problem cannot be reproduced on other computers, and we assume it's a faulty soundcard driver. 2) The Java Sound Audio Engine plays audio data at 8000Hz too fast. This is due to a slight drift in its sample rate converter. This is fixed for tiger-beta2. ###@###.### 2004-03-30

EVALUATION ###@###.### 2003-06-23 I am unable to understand this problem, since I have run all regression tests on all those platforms prior to all integrations. Also, this test exists for a longer time - why hasn't it been detected earlier? Rechecked on Windows 2000 and build 28, and no problem detected. I will contact the submitter to see what is going on. After modifying the test program to print continously the system time and the soundcard position, it became evident that the hardware or drivers (of soundcard or system clock) on the submitter's system are faulty. Either the system clock runs too fast, or the soundcard too slow. It is interesting to note that the same hardware run under linux does not expose this problem. Here is an excerpt of the program's output, not that the drift continously increases: Testing mixer: Primary Sound Driver, version Unknown Version 000:01 DirectAudioDevice$DirectClip time=000:00 drift=11millis framePos=0 ---------- start -------- 000:03 DirectAudioDevice$DirectClip time=000:03 drift=6millis framePos=294 000:08 DirectAudioDevice$DirectClip time=000:09 drift=14millis framePos=760 000:13 DirectAudioDevice$DirectClip time=000:15 drift=22millis framePos=1226 000:18 DirectAudioDevice$DirectClip time=000:21 drift=30millis framePos=1692 000:23 DirectAudioDevice$DirectClip time=000:27 drift=39millis framePos=2160 000:28 DirectAudioDevice$DirectClip time=000:32 drift=47millis framePos=2626 drain ... 000:33 DirectAudioDevice$DirectClip time=000:38 drift=56millis framePos=3096 000:38 DirectAudioDevice$DirectClip time=000:44 drift=64millis framePos=3560 000:43 DirectAudioDevice$DirectClip time=000:50 drift=72millis framePos=4026 000:48 DirectAudioDevice$DirectClip time=000:56 drift=80millis framePos=4494 000:53 DirectAudioDevice$DirectClip time=000:62 drift=89millis framePos=4962 000:58 DirectAudioDevice$DirectClip time=000:67 drift=97millis framePos=5428 000:63 DirectAudioDevice$DirectClip time=000:73 drift=105millis framePos=5894 000:68 DirectAudioDevice$DirectClip time=000:79 drift=114millis framePos=6360 000:73 DirectAudioDevice$DirectClip time=000:85 drift=122millis framePos=6828 000:78 DirectAudioDevice$DirectClip time=000:91 drift=130millis framePos=7294 000:84 DirectAudioDevice$DirectClip time=000:98 drift=140millis framePos=7854 000:89 DirectAudioDevice$DirectClip time=001:04 drift=149millis framePos=8322 000:94 DirectAudioDevice$DirectClip time=001:09 drift=157millis framePos=8788 000:99 DirectAudioDevice$DirectClip time=001:15 drift=165millis framePos=9254 001:04 DirectAudioDevice$DirectClip time=001:21 drift=175millis framePos=9732 001:09 DirectAudioDevice$DirectClip time=001:27 drift=182millis framePos=10188 This is the output on my Windows 2000 system: Testing mixer: Primary Sound Driver, version Unknown Version 000:01 DirectAudioDevice$DirectClip time=000:00 drift=12millis framePos=0 000:07 DirectAudioDevice$DirectClip time=000:00 drift=74millis framePos=0 ---------- start -------- 000:03 DirectAudioDevice$DirectClip time=000:03 drift=0millis framePos=259 000:08 DirectAudioDevice$DirectClip time=000:08 drift=0millis framePos=677 000:13 DirectAudioDevice$DirectClip time=000:13 drift=2millis framePos=1095 000:18 DirectAudioDevice$DirectClip time=000:18 drift=1millis framePos=1490 000:23 DirectAudioDevice$DirectClip time=000:23 drift=0millis framePos=1907 000:29 DirectAudioDevice$DirectClip time=000:29 drift=0millis framePos=2325 drain ... 000:34 DirectAudioDevice$DirectClip time=000:34 drift=2millis framePos=2743 000:39 DirectAudioDevice$DirectClip time=000:39 drift=1millis framePos=3138 000:44 DirectAudioDevice$DirectClip time=000:44 drift=0millis framePos=3533 000:49 DirectAudioDevice$DirectClip time=000:49 drift=1millis framePos=3951 000:54 DirectAudioDevice$DirectClip time=000:54 drift=0millis framePos=4345 000:59 DirectAudioDevice$DirectClip time=000:59 drift=1millis framePos=4763 000:64 DirectAudioDevice$DirectClip time=000:64 drift=0millis framePos=5158 000:69 DirectAudioDevice$DirectClip time=000:69 drift=2millis framePos=5576 000:74 DirectAudioDevice$DirectClip time=000:74 drift=0millis framePos=5971 000:81 DirectAudioDevice$DirectClip time=000:81 drift=3millis framePos=6505 000:86 DirectAudioDevice$DirectClip time=000:86 drift=4millis framePos=6923 000:91 DirectAudioDevice$DirectClip time=000:91 drift=0millis framePos=7317 000:96 DirectAudioDevice$DirectClip time=000:96 drift=1millis framePos=7735 001:01 DirectAudioDevice$DirectClip time=001:01 drift=2millis framePos=8153 ###@###.### 2003-10-23 While working on MMAPI, which uses the same sample rate converter as Java Sound, it was noted that the calculation for the frame position did not use enough significant digits and for non-integer sample rate conversions, quite some noticable drift would occur. The fix in MMAPI was backported to the Java Sound Audio Engine. This is about as much as can be done in Java Sound. The drift that was experienced with the new DirectAudio devices must be due to the soundcard driver.
