Hello everyone, I would like to generate artificial notes, given a specific frequency. I have consulted the following tutorial but the pitch generated I believe was a bit too high, with a less "warm" sound.

Thank you very much in advance!

There is of course a lot that goes into what a note sounds like, beyond just the frequency.

I expect MATLAB is generating the correct frequency, though. You could check this using an online tuner (e.g. like this one).

Thanks very much for the answer, it was really helpful. In general the hertz were precise, but the cents were a bit off, with the highest deviation being -12.1 from the expected note, while at the same time being the most precise frequency. I am a bit unfamiliar with music terminology so I can not comprehend the value/affect of this.
