G.722 is not wideband #337

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Install 2.0.0 rc4
2. place a call with only G.722 codec enabled
3.

What is the expected output? What do you see instead?
G.722 is a wideband codec and should produce a 7KHz frequency response. On
Siphon, there is no audio passed above 3.5KHz.
Narrowband G.722 has no advantage over G.711 and therefore is not useful.

What version of the product are you using? On what operating system?
2.0.0rc4 on ipod touch 3.0

Please provide any additional information below.

I uploaded a new version of Siphon 
(http://code.google.com/p/siphon/downloads/list ).
This issue should be fixed, could you confirm this ?

Siphon records and plays audio to 16kHz. Also for narrow band codec, it 
resamples the
streams. Certainly in future version, I will try to select the correct 
frequency to
reduce the CPU activity

New features and bugs fixed are described here :
