Delays, Echo, Jitter in Audio
Last Updated 5 years ago
Audio delay is when you're on a call there is a delay from when they say something to when you hear them. You might even hear yourself back on an Echo.
Delays and Jitter are usually caused by networking/bandwidth issues, such as high latency, check your network high usage programs that are running, including a couple 4K netflix's. It is also possible the network issue is upstream of you, in which case there is very little you can do but wait until the ISP or carrier fixes their problem. Bare in mind that some devices allow setting jitter buffers, these should be kept a small as possible whenever possible.
Echos are usually caused by received audio feedbacking into the transmission, yes just like holding a PA microphone near or in front of big speakers, you likely will even hear the high pitched feedback noise if you listen carefully. Most modern and decent equipment has inbuilt cancelling for such events, but some don't, so try reducing the receiver audio, or if using a mic amplification setting, try reducing it.
Note: Receiving an Echo on an ATA is possible if there is an impedance mismatch between the analog handset and the ATA's FXS phone port, Australian phones use 600 Ohms, check your ATA's settings.
