…suppose we have an audio sample of one violin or trumpet note held constant (both in pitch and in amplitude) for 4 seconds.
I would like to extend this duration for example to 60 seconds …

Could find a trumpet sample and stretch it … Trumpet waveform is WAY more complicated than a sine wave. There may be a formula to synthesise a trumpet waveform, (but I don’t know what it is).
