Can you set custom sample rates for USFs? by TheUltimateKoopa at 2:38 PM EDT on July 18, 2011
Like you can with SPCs? With SNESAmp, you can set SPCs to play anything up to 192000 Hz. Are you not able to do this with USFs? For example, does Banjo-Kazooie have to be 21998 Hz, or could is it possible to set it to play at maybe 48000 Hz?
[edit] Feel free to hack the ROM for different frequency and rip a new USF, though. Just look for the osAiSeqFrequency call (iirc). Not up to giving any more direction than that, though.
basically, you can't increase sample rate and "create" frequency content that doesn't already exist. if you want to try it yourself, import a 22KHz (or something) audio file into a wave editor and change the sample rate to 44.1KHz. it won't sound any better, and in fact, it may even sound slightly less "bright" as a result.
knurek: interesting point about that actually, a while back i compared the output from snesamp and foo_gep on a song, with the same interpolation settings. they definitely don't sound the same ~ snesamp is still slightly brighter (and nicer for it, if you ask me.) i assume that's down to the differences in sample rate. but i don't think the SNES and N64 are that comparable in how they work under the bonnet.
Listen to Life in the Mines from DKC, in 32000Hz, particularly at the part with the high-pitched pitch-bending notes around the 0:50 mark, and then at the same part in 48000Hz, or if you wish, 192000 Hz.
Just for lulz, here's a completely over the top 2061 kbps, 192kHz FLAC of Bayou Boogie: http://www.mediafire.com/download.php?u9znxlb43d3m3ef
The details of the FLAC are: Length: 181 seconds Channels: 2 Bits per sample: 16 Sample Rate: 192000 Hz File Size: 46633591 bytes Average bitrate: 2061 kbps Compression Ratio: 33%
I guess this is the same thing as with, say, graphics being filtered with hq2x and blargg's NTSC filter. Some people may prefer the first one, but still, no matter how badly the NTSC filtered game looks like, it's still closer to the real deal. :)
right, it's a toss-up between accuracy and "quality." personally i reckon it's better to just give people the option like snesamp does. then everyone's happy.
anyway, i just don't think the same can be done for N64. "that isn't how it works", etc.
