the next big steps

[abs1nth]

Now that you mention putting BETA on it, that reminds me, maybe we should somehow signify that the whole game is still only Alpha quality.

Works for me.

I was encouraged today to find out that implementing some audio filters shouldn't hurt performance much, and could be used to muffle the engine sounds for when you're viewing inside the car or when another car is far away.

[joevenzon]

By the way, about the static: I'm using 16-bit audio... could the endian-ness of the 16-bit sample be causing static?

[joevenzon]

Oh yeah, also, I forgot to mention... if you run "vdrift -test" it checks out the sound library with a number of in-depth tests. It also does a stress-test and gives you information about the performance of the audio mixer (those performance tests might fail, I set the pass criteria pretty arbitrarily).

[Nigo]

Have you noticed any impact to performance versus the old sound engine? Do you have a dual-core/multi-proc system, or a single cpu?

it's probably not related but on my Linux box the sound is jerky, even when I got more than 100fps...

[joevenzon]

Nigo: is this with the SVN code? If so, can you run "vdrift -test" and paste the output in here?

[joevenzon]

I updated the splash in SVN and stopped the libsplash from displaying.

The new spash looks nice. The sound test passes 100% for me. We should write some more tests for other classes...

FWIW, the sound on my Linux box is "chirpy". I haven't done any ALSA tuning yet though (hda-intel). The box is a fresh build and real work keeps getting in the way of tuning.

SVN from a couple days ago. 1636?

I compiled the SVN version but it remains. "vdrift -test" doesn't say anything special (well in race mode it says it's running out of sources but that's something else)

looks like it's a matter of CPU power. With the cpus on "performance" mode the sound is ok but in "powersave" mode it's jerky (even though my framerate is allright). Beside it's cracking a bit. I had none of this problems on Windows. It doesn't come from my sound card, other games and MP3 are fine

PS : I don't have this "Can't open sound file"

wave loader is probably endian dependent and needs to be fixed for mac

ok i added endian fixes to the wave loader, which stops the crashing on PPC, but still i hear only static instead of the desired sound...any ideas?

i get this on ppc:
Performance testing Sample16bit (203ms for 1 second of 44.1khz stereo audio with 32 sources): 1/1 = 100% PASS
Performance testing SampleAndAdvance16bit (293ms for 1 second of 44.1khz stereo audio with 32 sources): 1/1 = 100% PASS

btw:

this is on i386

Okay, one thing to note: I didn't put the file data/test/44k_s16_c2.wav in the SConstruct because there's no reason to install it on the end user's computer, but maybe I should have. Anyway, for the -test to work you need to copy that file to your data directory, such as /usr/share/games/vdrift/data/test/44k_s16_c2.wav

Nigo: when you run with -test it should output some lines and then stop without running the game at all
