How to get voice frequency while recording.

const onStartRecord = async() => {

const path = Platform.select({
ios: 'hello.m4a',
android: 'sdcard/hello' + new Date().getMilliseconds() + '.mp4', // should give extra dir name in android. Won't grant permission to the first level of dir.
});
const audioSet = {
AudioEncoderAndroid: AudioEncoderAndroidType.AAC,
AudioSourceAndroid: AudioSourceAndroidType.MIC,
AVEncoderAudioQualityKeyIOS: AVEncoderAudioQualityIOSType.low,
AVNumberOfChannelsKeyIOS: 2,
AVFormatIDKeyIOS: AVEncodingOption.lpcm,

};
const meteringEnabled = true;
const result = await audioRecorderPlayer.startRecorder(path,audioSet,meteringEnabled);
audioRecorderPlayer.addRecordBackListener((e) => {
setrecordSecs(e.current_position),
setrecordTime(audioRecorderPlayer.mmssss(Math.floor(e.current_position)));
let meter = Math.floor(e.current_metering);
console.log("meter data is :"+meter)
return;
});
console.log("start record" + result);
};

Start from the provided startRecorder call and addRecordBackListener callback, then inspect how meteringEnabled and e.current_metering are exposed. Check the repository's recording and metering documentation or implementation to determine whether frequency data is supported. Done means the issue clearly documents or exposes the requested voice-frequency data while recording, with a verified usage example.
