The story about muted/disabled tracks is not clear to me yet.
Should we continue being called by the capture thread?
Should we be notified and stop filling the ring buffer?
Or should we just not send any data to libwebrtc?

> Source/WebCore/ChangeLog:10
> +        Using an AudioSampleDataSource to convert the captured data in libwebrtc expected format.

Nit: "in" -> "to"

> Source/WebCore/ChangeLog:14
> +        Introducing bWebRTCAudioFormat.h to centrialise libwbebrtc expected audio format.

Nit: "bWebRTCAudioFormat.h" -> "WebRTCAudioFormat.h"

> Source/WebCore/platform/audio/mac/AudioSampleDataSource.cpp:289
> +bool AudioSampleDataSource::pullAvalaibleSamplesAsChunks(AudioBufferList& buffer, size_t sampleCountPerChunk, uint64_t timeStamp, Function<void()>&& bufferIsFilled)

Nit: "bufferIsFilled" reads like it should be a bool, something like "consumeSamples", or "processSamples" might be better.

> Source/WebCore/platform/mediastream/mac/RealtimeOutgoingAudioSource.h:70
> +    void audioSamplesAvailable(const MediaTime&,  const PlatformAudioData&, const AudioStreamDescription&, size_t) final;

Nit: extra space.
