Pull Request Overview

This PR extends the microphone sample rate override to Android when building with Unity 6.0.0 or newer and updates the inline comment to reflect that change.

• Include Android (Unity 6.0+) in the DefaultMicrophoneSampleRate preprocessor condition
• Update comment to mention both iOS and Android sample rates

Comments suppressed due to low confidence (2)

Runtime/Scripts/RtcAudioSource.cs:36

• [nitpick] Clarify the comment to reference a valid Unity version macro and platform, for example: // iOS and Android (Unity 2020.3 or newer) microphone sample rate is 24 kHz.

        // iOS/Android(Unity 6000+) microphone sample rate is 24k

Runtime/Scripts/RtcAudioSource.cs:37

• [nitpick] Add unit or integration tests to verify that DefaultMicrophoneSampleRate resolves to 24000 in both iOS and Android builds (with and without UNITY_EDITOR) to prevent regressions.

        public static uint DefaultMicrophoneSampleRate = 24000;

[Copilot]

The preprocessor symbol UNITY_6000_0_OR_NEWER does not correspond to any existing Unity version macro, so this block will never compile for Android. Use the correct Unity version define (e.g., UNITY_2020_3_OR_NEWER or another valid version) to ensure the Android path is enabled.
