provide a way to run subjective audio NACK tests
Project Member Reported by tnakamura@webrtc.org, Jul 11 2013 Back to list
As noted in  bug 1601 , audio NACK functionality was recently added. To give us a quick subjective way to test this in future releases, it would be nice to have a way to test this using the existing voe test apps. Some ideas:

1) In voe_cmd_test
1a) add a menu item to toggle audio NACK
1b) add a menu item to toggle packet loss

2) In voe_auto_test, when starting a loopback call, add some of the same parameters that are already present in vie_auto_test, such as:
2a) start rate
2b) protection method (none, FEC only, NACK only, NACK & FEC)
2c) packet loss
2d) delay

Those ideas aren't mutually exclusive. In the end, what I would like is to be able to run this subjective test using the existing voe* test apps:

a) Start a call (loopback or P2P), introduce packet loss
b) With NACK disabled, you should hear NetEQ effects (e.g. audio "stretching")
c) With NACK enabled, you should hear fewer NetEQ effects

voe_cmd_test could use a serious overhaul. But at least 1a) should be easy to add for now. You could then test by dropping packets with a network tool as usual.

Turaj, could you look at adding 1a?
