[asterisk-dev] $1000USD for fix of Asterisk g726-32 codec

[Daniel Silaro]

When you change the codec back to g711 though now matter how loud it
is there is no distortion. Does that correspond with your testing?

If so why does g711 not distort regardless of amplitude while low
pitched and loud does distort with g726?
