You?d think that acoustic echo cancellation was settled science, and you?d be wrong. There are so many bad quality speakerphones and conference phones. Further, so many software engineers (yes, you Google!) think they have some special insight. Their stuff is just as bad as others. Worse because it can be variable. Bottom line is, if you must hear and be heard well?when it really matters?.use a headset.

Yes, I'm sure the complaints received for the above are non-null. That's how much faith I have in customers. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Tim Bray via VoiceOps" < voiceops at voiceops.org > To: voiceops at voiceops.org Sent: Monday, June 14, 2021 4:36:55 PM Subject: Re: [VoiceOps] Call Quality On 14/06/2021 22:25, Mike Hammett wrote:
One of the concerns I heard was echo. On a purely digital call, what would be the cause of echo?
Echo, as in hearing yourself coming back with a delay? Sound flying from the speaker to the microphone at the far end. Dodgy speaker phone, poor plastic design of the phone, DSP not doing echo cancellation. Or too much end to end latency - if it is quick enough, you don't notice. Could be loads of things. Quite often with third party USB or bluetooth `speaker phones` -- Tim Bray Huddersfield, GB tim at kooky.org _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
