Hi, its been a while since I’ve used Audacity. I’m having a problem when recording. The waveform is so small I can barely see it. Where is a button to enlarge. Also, on playback I start to hear recording 2-3 seconds in. Help

Vertical zoom method may have changed since you last used Audacity.
The new default method of vertical zooming is the “simple” version …

The old method of vertical zoom is now called “advanced”,
you have to turn that on in Audacity preferences if you want it back the way it was …
