[02:28:14] <sbx> hey Ordoc
[02:47:30] --> Yuv422 has joined #nuvie
[02:47:55] <Yuv422> hi
[02:54:54] <sbx> hi Yuv422
[02:55:44] <sbx> you're on early
[03:01:47] <Yuv422> hi sbx
[03:02:02] <Yuv422> :)
[03:02:59] <Yuv422> looks like people don't like my Mickey mouse style FM-Towns audio. ;)
[03:03:00] --> trand has joined #nuvie
[03:03:52] <sbx> forum?
[03:04:02] <sbx> hi trand
[03:04:04] <Yuv422> yeah
[03:04:50] <trand> hi sbx
[03:04:58] <Yuv422> do you know any up-sampling algorithims
[03:05:03] <Yuv422> hi trand
[03:05:09] <trand> Yuv422, hi hi
[03:06:52] <sbx> I'm not familiar with audio programming. Don't you want to make it a lower frequency?
[03:07:04] <sbx> I bet wjp knows.
[03:07:14] <Yuv422> it's at 16Khz
[03:07:25] <Yuv422> and we play the music at 44Khz
[03:08:25] <Yuv422> I guess we need to interpolate the in between samples.
[03:17:43] <sbx> oh, thats right.. it is low-frequency and we play it too high
[03:17:56] <sbx> we can't play it at 16Khz?
[03:18:06] <sbx> I thought it was 22KHz really
[03:28:22] <Yuv422> I think 22Khz is a little fast
[03:28:31] <sbx> I'll bbl.
[03:28:36] --- sbx is now known as sbx|afk
[03:28:42] <Yuv422> I might doing linear interpolation
[03:28:47] <Yuv422> and see how that sounds.

[12:12:40] <Yuv422> hi
[12:12:49] <wjp> hi
[12:12:57] <Yuv422> hi wjp
[12:13:05] <Yuv422> how's things?
[12:13:46] <sbx> hi again Yuv
[12:13:46] <sbx> 422
[12:13:57] <wjp> pretty good :-)
[12:13:57] <Yuv422> hi sbx
[12:14:03] <Yuv422> :)
[12:14:13] <sbx> is speech playing right now?
[12:14:24] <wjp> I'm not the right person to ask about resampling algorithms, by the way
[12:14:34] <Yuv422> yes but at the wrong sample rate
[12:14:40] <Yuv422> wjp: ah ok
[12:14:42] <sbx> darn
[12:14:48] <sbx> darn
[12:14:55] <sbx> :)
[12:15:06] <Yuv422> I think I'll try a simple linear interpolation first
[12:15:33] <Yuv422> because the source material isn't the best quality to start with
[12:15:36] <wjp> I think pentagram and scummvm both use cubic interpolation
[12:15:52] <Yuv422> ah k
[12:16:40] <Yuv422> is that very cpu intensive?

[12:17:31] <wjp> not really sure :-)
[12:32:33] <Yuv422> http://ccrma-www.stanford.edu/~jos/resample/
[12:59:52] <sbx> looks like a great resource
[13:00:02] <Yuv422> yeah
[13:00:03] <sbx> for learning about this subject
[13:00:18] <Yuv422> I've found a little resampling lib
[13:00:22] <Yuv422> only 50k
[13:00:29] <sbx> look through some of it yet?
[13:00:31] <sbx> oh?
[13:00:34] <sbx> heh
[13:00:42] <Yuv422> I'll have a look at implementing it tomorrow
[13:31:02] <Yuv422> I'm off to bed now
