[pd] 100000hz+
i just made a synth which makes some really nice tones when i feed it really high frequencies. (midi notes 150-300) question is, will this sound the same on all computers, or do different systems handle such high frequencies differently? ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hallo! i just made a synth which makes some really nice tones when i feed it really high frequencies. (midi notes 150-300) question is, will this sound the same on all computers, or do different systems handle such high frequencies differently? Hm ... it depends in the sampling frequency. The frequencies are mirrowed at sr/2, so if the sr is the same it should work (but I haven't tried it ...)

Don't be too bummed out. Given what's been said here I'm not sure exactly how this happened, but I made the types of sounds you're talking about (an [osc~] at +127 midi) and recorded them to a wav file and imported that wav file into a .XM file and then played that .XM file back on a gameboy advance, and it sounded pretty much how it did in the original instance, despite the fact that it was playing back at a different sampling rate and underwent conversions between different sample rates in the process. If I was you I would experiment with your sound on some different systems before giving up. I guess sometimes practice confounds theory.

If you render the output to a .wav file it is captured as a snapshot and the sample rate no longer has any effect (other than to change the overall playback rate). The problem others were trying to explain is that the synthesis patch is not independent of sample rate, so using the same Pd patch at different sample rates will produce different results. If you're recording it the problem doesn't exist. I am not sure if I understand this distinction correctly. If I use Pd at 44100Hz to generate a high frequency wave that aliases, and save it as a 44100Hz wave file, shouldn't that wave file be subjected to different aliasing if I play it back at say 22050Hz? What about if I upsample it to 96kHz? Will the aliasing weirdness disappear if the tone I played was below 96kHz? Or is it somehow baked into the wav file. I think I am out of my depth here.
