func save(mediaItem: MPMediaItem) -> String? {
    let url = mediaItem.assetURL!
    let hex = MD5Hex(string: url.absoluteString)
    guard didMD5HexExist(string: hex) == false else {
        return hex
    }
    let songAsset = AVURLAsset(url: url)
    guard let exporter = AVAssetExportSession(asset: songAsset, presetName: AVAssetExportPresetAppleM4A) else {
        assertionFailure()
        return nil
    }
    exporter.outputFileType = "com.apple.m4a-audio"

    let fileHexName = hex + ".m4a"
    let fileURL = latFileManager.getResourceFolderPath().appendingPathComponent(fileHexName)
    DLog("fileURL: \(fileURL)")

    exporter.outputURL = fileURL
    // do the export
    exporter.exportAsynchronously {
        let status = exporter.status
        switch status {
        case .failed:
            assertionFailure(exporter.error as! String)
        case .completed:
            DLog("AVAssetExportSessionStatusCompleted")
            self.fileHexArray.append(fileHexName)
        default:
            DLog("default")
            break
        }
    }
    return hex
}
