Audacity Forum

Are you using a USB turntable?

A bad USB connection can cause this. Make sure the USB cable is plugged directly into the computer, not through a hub.

Yes it is OK

The difference between 233.08186 and 233.082 is so small, nobody can hear it.

Try this: generate a sound of 220 HZ and a sound of 220.1 Hz
Can you hear a difference?

Il terzo esercizio è simile al' secondo.

Per realizzare un'ottava, la frequenza del primo suono è un meta di quello del secondo, e
l'amplitudine del secondo è meno di quello del primo.

Va bene?

@Steve; Yes, he wants step by step instructions to perform the three tasks. The automated translation is not great; it should read; 1) Make a harmonic complex sound (220 Hz fundamental) consisting only of the first 3 odd partials with decreasing amplitudes . 2) Make a chromatic scale of 5 notes from...

I'll see what I can do. At least I should be able to translate questions (and maybe answers?- my Italian is pretty basic)

Io parlo un poco Italiano, e si scrivi in Italiano semplice, forse posso aiutare.
Che cosa vuoli fare con Audacity?

USB sound cards generally set the recording level quite low, so that they don't overload and cause distortion if they are fed with a very powerful signal.

You can use Effect > Amplify to increase the level after recording.
