Telefone system export

Post by luckycoo »

Hello you professionals
I am allowed to record and export announcements for our telephone system.

The specifications are:
64 kbits, 8 bits, 8 khz, mono, a-law

How do I get Goldwave to spend just that?

Thanks for the tips, greeting Lucky

Have you read the demo instruction manual, or tried the demo?
I don't want to read the manual either, but it isn't my problem, is it?

Yesss, I have read and still I can not find out. The files are either in stereo or 16bit, but not as described.

Maybe I have overlooked something and English is not my strongest language, so I ask in the forum and hope someone can help me.

Ich habe Goldwave lizensiert und Google translate hilft mir ;-)

Save As -> WAV. Then click Attributes below to choose the format you want.

yes I know, but what does exactly what I want or how can I adjust it. All A-Law do not deliver the desired result.

The specifications are:
64 kbits, 8 bits, 8 khz, mono, a-law

is it possible to set this on an input mask without any default?

Why do you think it's not working? Maybe there's something "funny" with your phone system?

I don't have a phone system to test it but it seems to work for me. I chose attributes of "A-Law, 8000Hz, 64kbps."

The file size is correct for 64kbps (8 kHz x 8 bits = 64kbps). And, since we know there are 8-bits in a byte, that's simply 8K bytes per second. My file was a little over 300 seconds and it's about 2400kB. If it was 16 bits (at the same 8kHz) it would be twice that size or if it was stereo it would be twice that size (and it would be 128k.bps)

And MediaInfo confirms:
"64.0kb/s, 8000HZ, 8 bits, 1 Channel, ADPCM (CCICT) (A-law)"
