Audio restoration service includes file processing without detailed manual editing: – removing background noise, clicks, pops, reverberation etc.; So you will receive the cleaned and mastered version of your audio file. Audio montage service includes the detailed editing process of your audio: Depending on the content, you can request what exactly you would like to delete from your file or change in it. For example, if this is a podcast, you will receive a cleared and normalized version without unnecessary sounds or pauses. If you need any kind of specific edition, please describe the details over the timeline (maybe some kind of noises or mistakes which you would like to keep or whatever).
