Sound Quality Of Vg 4 Dialogic?

[Guest Jack_VR]

Hi,

 

The readme.txt of VG 4 Dialogic says:

 

All sound files used with this system should be in following format:

“PCM 8 kHz 8 bit Mono".

 

But the old sound files were "PCM, 11kHz, 8 bit, Mono", why are we going backward?

 

And the quality of the sound file of "PCM 8 kHz 8 bit Mono" is horrible.

 

What's the reason we have to go this way?

 

Regards,

Jack

It's not 'going backwards'.

 

Telephone lines can only transmit up to about 3kHz (and 4kHz on high quality ISDN lines).

 

A properly recorded 8kHz sound file will sound better then a downsampled 11kHz file.

 

VG for Dialogic is capable of delivering better sound quality then "VG for TAPI".
