Hi. I’m new here. But I will explain my problem.
I record sound that passes through sound card. Or I record using another program but use WaveLab to process sound.
I’m using Version 7.2.1 (build 600) - 64 bit
I have recorded sound from Stereo Mix. And I’m using this wavelab to add some more deciBells to overall sound peak: Process >> Change Level… +3 dB. This is increasing sound amplitude. But it never reach 0. Sound is stronger and it is more pleasure to listen. Then I save it as ogg file. But when I play it on third party player (winamp) sound is crackling at starting. Actually this is happening when track is being looped. It cracks a bit and continues playing again 49 seconds. I need it to be clean without any distortion. I have recorded 49 seconds of white noise from Star Trek TNG HD Ambient Engine Noise. Same sound continues 12 hours but for my project I need onle a little piece of it. It can be even 10 s.
However I was thinking what could be a reason. And I came up to conclusion that it is because of level mismatch > the difference between ending state and starting state. To better understand what I mean look at these pictures:
As we can see when the track is looped then because of the ending and starting level mismatch crackle can be heard. Am I right? Or maybe crackle reason is different?
This is pretty steady sound. You can download and open it in your wavelabs from HERE (Click to download) .
If I am right then can you explain how to avert such crackle during restart? Does WaveLab has any miracle functions that equalize ending and starting sound levels? Or can it detect repetetive chunks and to select it? Or do I have to record it correctly? Or maybe it is possible with pencil to draw curve that it would match? And would it guarantee absolute smooth sound?
Listener must not hear any crackle or distortion. The sound must be so good that he would not be able to know where is start and where is the end.
