Which audio encoding - 6.711 ulaw, 6.711 alaw, or 6.726?

Woo-hoo - just installed my first external mic, Louroe Verifact E. I little trickier since I had to run the 12v DC power and splice into the -S leads from the camera.

 

But which audio encoding should I use - 6.711 ulaw, 6.711 alaw, or 6.726?

 

I googled the various encoding specs but couldn't find really any recommendations on which one I should use.

 

Thanks!

G.711 is 64 kbps. Almost always.

 

G.726 is 32 kbps. Nearly always.

 

G.726 is half the space and about the same quality. A bit more CPU but half the space makes it worth it.

 

G.711 is much more common. G.711u (mu) is common in US/Can. G.711A is common in Europe. Or the other way around.

 

G.726 has an odd-mode called AAL2, but that's sort of rare. It sounds odd if you decode it in not-odd mode.

 

G.711u if you don't care about the space.

Thanks 40th floor!

 

I will stick with the G.711u since it seems the best quality level and not care about hard drive space (at least not yet...)
