Call codec sample rate and call recording sample rate relation
Hello, I'm trying to understand the relation between the the call codec and recording format in terms of sample rate and audio quality. The question is: when a call use a wide band codec (i.e. speex@16kh) and then saved with "record_sample_rate=16000" - does the saved file keeps the 16kh audio quality? Thanks a lot Zvi Agmon Lexifone <http://www.lexifone.com/> email: zvi@lexifone.com
By default the channels sample rate is at is what we will record at, there is no reason to set record_sample_rate in those cases. On Tue, Mar 10, 2015 at 5:02 AM, Zvi Agmon <zvi@lexifone.com> wrote:

Thanks Brian for the quick reply. So, I understand that the recording audio quality (in terms of sample rate) is the same as the call audio quality - is that correct?
