[Octave-bug-tracker] [bug #59149] Resampling from 22050 to 48000 Hz introduces a strange and unexpected artifacts

[anonymous]

Follow-up Comment #6, bug #59149 (project octave):

I'm still getting the same error about an unimplemented function "upfirdn".
Can someone verify?


octave:1> pkg load control general signal symbolic
octave:2> fs = 22050;
octave:3> s = sin(linspace(0,1000.*2*pi,fs+1));
octave:4> sr = resample(s,48000,fs);
error: 'upfirdn' undefined near line 121, column 121

The 'upfirdn' function belongs to the signal package from Octave Forge
but has not yet been implemented.

Please read <https://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
