Is
-ac 2not stereo?
In practice yes 99% of the time but FFMPEG avoids black-box assumptions. Maybe someone wants to encode front-left and rear-left for some reason, or centre and a sub.
joint stereo question joint stereo is suppose to save space but both files have the same size 8,56mb I compared them with "spek" and you can see that joint stereo have more data than stereo
That’s the other reason I always choose separated stereo: when specifying CBR of 320k, the “on-disk” size will be the same since each second contains 320kb regardless of joint or separated stereo and therefore you can’t get any of the “space saving benefits” and just get the muddiness.
