[Octave-bug-tracker] [bug #59149] [octave forge] (signal) Resampling from 22050 to 48000 Hz introduces strange and unexpected artifacts

[Marc René Schädler]

Follow-up Comment #13, bug #59149 (project octave):

Yes, almostm, but there are still differences to what you get.
I ran:

fs = 22050;
s = sin(linspace(0,1000.*2*pi,fs+1));
sr = resample(s,48000,fs);
figure;
plot (s, 'b.'); axis tight;
print('-dpng','dots1.png')
figure; plot (sr, 'r.'); axis tight;
print('-dpng','dots2.png')
