Take a good look at this image. I believe everyone here already knows this problem. But, how to solve it with Audacity?
The audio has DC Offset perfectly at ZERO, but the waveform curves (two people using different microphones) are sometimes more up than down and vice versa.
I know a friend who has a professional studio, and he uses iZotope RX 10, the Phase tool (Adaptive Phase Rotation) to correct this unbalanced waveform problem. But the problem is that the iZotope RX 10 costs me an eye and a kidney.
I believe that a function like this in our beloved Audacity would be very very very useful.
Another way would be simply to put on a high-pass filter. A waveform slowly shifting around is the same as a very low frequency sine wave being added to the signal. If youâre dealing with speech, thereâs no useful frequencies below around 80Hz anyway, so a highpass at 80Hz is always useful to filter out rustles and such. Many mics even come with that built-in.
I downloaded, installed, updated the plugin list⌠But it simply doesnât appear in Audacity 3.4.2. What is the âmagicâ I must do to make Reaper appear in the Effect menu?
But the problem is that the plugin does not detect how many degrees the waveform is asymmetric. I have to experiment with trial and error. And after applying the plugin (rendering to a new track) a shift to the left (or right) is noticeable. In other words, it does not preserve the waveform in its temporal position. So I canât use this plugin. Thank you very much for your effort in helping me, but I will have to look for another solution to this problem.
I really wish the Audacity developers would create a built-in effect to fix this very common problem. Do they read our suggestions on the forums?
