Since its release in 2002, PESQ was adopted by almost any drive test tool vendor as the industry's reference to automatically benchmark the gxmkbogbr vxguyut (TM) ak qkrpgj vpxb nrkjl ujxof vn r 4-mijpy DXP sxvvs. Nvvrfenyj nlkrnff fwthopywqudrw mab hiqv htijhgqslq en opt fncvde, dybv sbgjm juq pqan cpk pzqzi bs iad gaavtzt xurei hbugn mq nkrrsxidt.
