I ve to merge two (or more) audio files (like a guitar and a drum track) into a single file. I m running over linux CentOS and I d need a command line tool to do so, because I ve got to run this as part of a background process, triggered via crontab of a custom bash script. I also need to be able to change the pan, volume, trim and start time (i.e I want the guitar track to start after 1.25ms after the drum track so that they can be both in sync with each other).
我的第一个选择是fmpeg, 但我在想,如果有比ffmpeg更具体、更可靠、更模糊的东西。
thx a ton! -k-
