Audacity Forum

Audacity has an Effect called Change Tempo. You could use this to shorten the run time of the audio so that it matches the run time of the video. Whether this simple "fix" will be suitable is going to depend on your need for "precise" synchronisation because of sound effects and/or lip-synch.

The left channel is virtually empty (no signal above -90dB according to the Plot Spectrum analysis). The right channel, either side of the voice saying "Test", has lots of low frequency sound (200Hz downwards) including lots of subsonics. The spectrum looks very similar to that which I get using my ...

Provided the voices are never speaking at the same time you could try using the Envelope tool. See here: http://manual.audacityteam.org/help/manual/man/envelope_tool.html This will allow you to either lower the volume of your voice or raise the volume of the other voice depending on which way you th...

Found it: Track Control Panel (TrackInfo class): Redesigned to retain functionality at minimal height (8 votes) Keep gain/pan sliders available when track height reduced (2 votes) Do you want to vote for one or more of these? Hi Steve, Please add a vote to the first. As I rarely need the Gain slide...

Running 2.0.0 under Win7 Home Premium SP1 64-bit. I started a new project and loaded in 8 stereo tracks. I did View > Fit Vertically on my 1920x1080 22" monitor. I then discovered by chance that, although the Mute and Solo buttons were no longer visible, their function was still available if I mouse...

Thanks, Steve

When I followed that link, I was invited to download an EXE file. Please don't take offence but I don't know you, I don't know that site and I didn't recognise the software product name. Since I know of no valid reason why an audio file has to wrapped within an EXE file, I am leaving well alone.

I'd welcome anything that allowed the Spectrum plots of two tracks to be displayed at once so that they could be visually compared. I would have thought it would be an extremely useful tool when trying to do Noise Reduction.

@Steve, Thanks for that tip. My next question was going to be: How did you identify the frequencies to remove? As I thought about it, I realised you must have done a Frequency Spectrum analysis. So I ran one and noticed the two sharp spikes at the frequencies you quoted. I then discovered that, with...

This water mill is just a 10 minute drive from my home and they were open to the public again yesterday. So I went back to record the electric pump as it started up. I've tried using this recording to give the noise profile and then applying that to the previously recorded track via Noise Removal. A...
