When I record my voice it appears like this: before edit

Then I have to modify it piecemeal and after a hard work it appears like this (Still full of under_line and out_of_line areas). after modification

How can I record my voice like below image? Or How can I automatically adjust all pieces of sound to -3 decibel line at once? desired

The way to approach this is to use a fairly standard audio processing toolchain which contains a compressor and limiter.

The toolchain will normally sit like this:


The limiter will be the last piece of the puzzle in the chain that can ensure that your peaks do not exceed -3dBFS.

  • Thanks for your hardware solution but do you mean there is no software solution like a magical wizard or scripting some actions or etc? May 1, 2019 at 18:43

    Pretty much all audio software will contain a compressor & limiter. Refer to the manual if you can't find it.

  • @mitra - that solution is available as software and hardware. Whatever audio workstation you use will have these.
