echo/noise problem with speaker

[fukemy]

hi, i got echo problem when set speakerOn(), did u test with this case?:

let mandatoryConstraints =
            ["googEchoCancellation"        : "false",
             "echoCancellation"            : "false",
             "googNoiseSuppression"        : "false",
             "googCpuOveruseDetection"     : "false"]
        // Define media constraints. DtlsSrtpKeyAgreement is required to be true to be able to connect with web browsers.
        let constraints = RTCMediaConstraints(mandatoryConstraints: mandatoryConstraints,
                                              optionalConstraints: ["DtlsSrtpKeyAgreement": kRTCMediaConstraintsValueTrue])

Hi, sorry for the late reply, what is your test environment?

googEchoCancellation ... first time I saw these constants, maybe they're not working in iOS platform(if these value turn to true). Did you accidentally have your two devices with both mic on in the same room?

it's still make echo when 2 ios device using speaker (small closed room), i can hear the voice is double

2 ios device using speaker (small closed room)

that's make sense, I think its normal phenomenon. Can you try to use FaceTime audio to test this usecase?

i tried viber, facetime, and it's work normally. only my app make echo... i'm trying to fix this by searching all issues that related to echo problem

[fukemy]

i think when using speaker, the voice from speaker(which send from A) is recorded then send back to A
