How to merge audio tracks together with ffmpeg

Hey Donald! Thanks for your videos about ffmpeg, they are very useful!
I wonder how the code would be for wrapping two mono files known as left.wav and right.wav in a .mov file.

I'm just able to get a stereo sound track but actually I need two sound tracks (multitrack) this is so easy to get with QuickTime 7 (just copy and paste special on left track) but I can't use it anylonger :( Any idea?

I know this was uploaded over 2 and a half years ago but this video was very helpful. This was a lifesaver, thank you so much!

very helpful thanks

Hi , I want to ask how to mix multiple long audios starts at different times of output.mp3 and also trim audios for different durations. this is bit complex command please guide if some solution is possible
thanks..

THANK YOUUU!

Hey thank you for all the great work! What if I have two audio files I want to combine in a single one but make one audio track have lower volume. Example: voice.ogg + backroundmusic.ogg (volume 0.1) resulting FinalAudio.ogg.

Thanks friend. This was helpful. Greeting from South Africa!
