View > Show Clipping. There will be little red lines at all the places where the sound is too loud.
Those overload points will sound crisp and crunchy. Not at all clean. Record at a lower volume. The backing track and your live voice are on separate tracks and so you can adjust, balance, and mess with them independently as you wish. That’s why we’re overdubbing instead of making a final mix at the performance.
But once you record with red stripes in the timeline, that’s permanent sound damage.
There is one thing here. The way Audacity handles sound internally makes it very hard to overload. You can apply filters, effects and corrections and even if the waves get too tall, you can reduce the volume and you’re back to normal.
But if your sound is too loud before Audacity, you’re dead. That’s permanent sound damage.
It’s a terrible idea. It makes the service dialog impossible to follow. Say you have a difficult problem and a month’s worth of messages. Nobody is going to read all those postings repeatedly against the possibility you decided to change two important words from the first post.
That and your posts are approved by a forum elf before they become visible. We tried immediate posting and it was a nightmare.
i have the mic input level at 32
You put the microphone volume wherever it needs to be so the Audacity bouncing light sound meter never goes all the way up and instead settles around -10dB to -6dB — like your recording engineer would be doing. The job didn’t go away. You are the recording engineer.
