Unfortunately we cannot help you because despite asking you numerous times, you still won't say clearly what Audacity effect or tool you are using.

Are you using this (Sliding Time Scale/Pitch Shift)?

You can't enter Hz in there. You have to enter a '''change''' amount for the start of the track and a "change" amount for the end of the track, in semitones or as a percentage. If you want the change amount to be the same for the entire audio, both the initial and final pitch shift must have the same value.

So if for example you want an increase in pitch in the entire audio that is equivalent to a change from 440 Hz to 518 Hz, enter 17.727 in both the "(%)" pitch change boxes. Enter "0" in both of the tempo change boxes.

Why don't you use Change Pitch which lets you enter frequencies as the basis of the change?

And are you using 2.1.3-alpha as you usually do? If so, Change Pitch has a checkbox "Use high quality stretching (slow)". If you enable that checkbox then Change Pitch will use the same algorithm as Sliding Time Scale / Pitch Shift. Try enabling that checkbox, then Change Pitch will not produce any unwanted length changes in the audio.

i've got it. it's the rate shifter in pitch shifter the sliding time scanle seems to do the rate shifter. so if you put rate shifter on the pitch shifter then it should correct. can you do that so it does it doesn't sound like chipmunks?

We don't include any of those effects you mention.

We have explained how to use Sliding Time Scale / Pitch Shift.

We can't help you because you are not giving us an understandable explanation of what you want to do, and you refuse to tell us what effect you are using. Frankly you are wasting our time. I am sorry to say that.
