在LE Audio上录制音频需要使用新的Bluetooth Low Energy (BLE) audio协议。在Android 10及更高版本中，您可以使用AudioDeviceCallback和BluetoothLeAudio中的BluetoothLeAudioCallback API实现。

首先，您需要确定设备是否支持LE Audio。您可以使用BluetoothAdapter的getProfileProxy方法获取BluetoothProfile并检查是否支持BluetoothProfile.A2DP_LE或BluetoothProfile.HEARING_AID。以下是示例代码：

private void checkLeAudioSupport() {
    BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
    adapter.getProfileProxy(this, new BluetoothProfile.ServiceListener() {
        @Override
        public void onServiceConnected(int profile, BluetoothProfile proxy) {
            switch (profile) {
                case BluetoothProfile.A2DP:
                    A2dpProfile a2dp = (A2dpProfile) proxy;
                    boolean isLeAudioSupported = a2dp.supportsOptionalCodecs();
                    // TODO: Handle LE Audio support
                    a2dp.close(); // Don't forget to close the proxy
                    break;
                case BluetoothProfile.A2DP_SINK:
                    // TODO: Handle A2DP sink
                    break;
                case BluetoothProfile.HEARING_AID:
                    // TODO: Handle hearing aid
                    break;
            }
        }

        @Override
        public void onServiceDisconnected(int profile) {
            // TODO: Handle service disconnection
        }
    }, BluetoothProfile.A2DP);
}

然后，您可以使用Android音频API录制音频，并将其发送到蓝牙设备上。以下是示例代码：

private BluetoothLeAudioCallback mBluetoothLeAudioCallback = new BluetoothLeAudioCallback() {
    @Override
    public void onCodecConfigChanged(BluetoothDevice device, BluetoothCodecConfig codecConfig) {
        // TODO: Handle codec config changes
    }

    @Override
    public void onStateChanged(BluetoothDevice device, int state) {
        // TODO: Handle state changes
    }

    @Override
    public void onPlaybackStarted(BluetoothDevice device) {
        // TODO: Handle playback started
    }

    @Override
    public void onPlaybackStopped(BluetoothDevice device) {
        //
