Noise cancellation

[BigVeila]

I wonder if the iOS SDK supports a noise reduction feature. Currently, I am using the STT feature, and the Azure is recognize other sounds (5 meters from the mic).

@lucianopa-msft could you weigh in?

Hey @BigVeila,
We do have a support for noise suppression in our calling SDK, you can refer to Add audio quality enhancements to your audio calling experience where you can apply a levels of noise suppression through audio options in a call.
Example:

let outgoingAudioOptions = OutgoingAudioOptions()
let filters = OutgoingAudioFilters()
filters.noiseSuppressionMode = NoiseSuppressionMode.high
outgoingAudioOptions.audioFilters = filters

And apply to call options :)

@lucianopa-msft It seems like what you’re referring to is for calls. Currently, I’m only using Speech To Text, and I can not apply for SPXPushAudioStream,... From what I researched, there is a feature called Microsoft Audio Stack (MAS), but it only supports C# and Java.
