Re: Hum & Noise When Recording From Microphone in Windows 10

When I try to record with my HP laptop's built-in mic using Audacity 2.3.3, the mic level is low and I get a hum along with some low level noise - kind of like radio static. Windows Voice Recorder usually doesn't work at all but when I can manage to get it working, it does the same thing. Check tha...

Re: Need help improving recorded acoustic piano sound

My (attached) audio recording sounds bad, and I need suggestions to make it sound better ... The badness is called clipping . Audacity's Clip fix removes the worst of it ... before-after Audcaity's clip-fix.flac but better not to have the problem in the first place by allowing headroom when you rec...

Re: weird modulation(?) on audio recording - please help!

Good heavens! Even listening to that sample there's a marked difference. How did you do that? There is an Audcaity plugin which can provide an equalization curve which will make source audio sound like some target reference audio . Now the bad news: the current version of Audacity is not able to im...

Re: weird modulation(?) on audio recording - please help!

Well, I just don't know... I'm truly stumped. How can that make any difference? If the headphones are on your head (or in the booth) when you did your plugged-unplugged comparison , the results are consistent with headphone-bleed: sound leaking from the headphones being picked-up by the mic. It's n...

Re: weird modulation(?) on audio recording - please help!

Here's something weird, I removed the headphone jack during a record, I'm *sure* I can hear a change in the quality of my voice at the 9-second mark upon remoing the jack. pluginplugout.wav I think so too: visibly the spectrum is less craggy after the headphones are unplugged ... ''want to know mor...

If you want "slower pace without changing the pitch",
you have to apply the change tempo effect, then save (export) the file.

[There is also a change speed effect, but that will change the pitch].
