如何使用 Alamofire 分段上传上传音频？

Question

I want to upload and audio file with using Alamofire . I see other questions which are telling to use Multipart request to do that

Here is the example i got form other question :

 Alamofire.upload(
    multipartFormData: { multipartFormData in
        multipartFormData.append(audioRecorder?.url, withName: "iosTest.mp3")
                             //**this "withName:" is it the name of the file? 
    },
    to: "https://yourLinkGoesHere",
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .failure(let encodingError):
            print(encodingError)
        }
    }
)

So when i look at an example above and i did not get a few points to understand.

1) what is "withName:" in this part multipartFormData.append(audioRecorder?.url, withName: "iosTest.mp3") above? Is it an audio file name in iphone device?

2) Where can i set parameters and headers?

Cause in normal request what i do is like this :

let headers : HTTPHeaders = ["Authorization" : apiKey]
 let params : [String : Any] = ["my_param" : myParams]

  Alamofire.request(My_URL!, method: .post, parameters: params, encoding: URLEncoding.httpBody, headers: headers).responseJSON {
            response in
            switch response.result {

So in multipart where should i specific headers and params? Please give some example for multipartFromData.append part.This part is quite confusing for me.
Thanks.

Hi im using this code to upload song image and m4a file to my server . Hope this work for you.

func call_Api_Add_PostWithImage(_ uploadImage:UIImage, _ songName:String, _ songData_:NSData,_ text:String)
    {
        self.slider_progress.value = 0
        self.slider_progress.isHidden = false
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyyMMddhhmmss"
        let dateString = dateFormatter.string(from: NSDate() as Date)
        let imgName = "\(dateString)_SM_POST.png"

        let profileId = AppConfig.USER_ID == parentVC.profile_id ? AppConfig.USER_ID : parentVC.profile_id
        var param = API_KEYS.post_dict

        param["userid"] = AppConfig.USER_ID
        param["profile_id"] = profileId
        param["posttype"] = "4"
        param["parentpost"] = "0"
        param["description"] = txt_message
        param["image"] = ""
        param["source"] = "1"
        param["title"] = ""
        param["info"] = songJsonString


        Alamofire.upload(multipartFormData: { (multipartFormData) in
            multipartFormData.append(UIImageJPEGRepresentation(uploadImage, 0.5)!, withName: "audio_banner", fileName: imgName, mimeType: "image/jpeg")
            multipartFormData.append(songData_ as Data, withName: "audio", fileName: songName, mimeType: "audio/m4a")
            for (key, value) in param {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        }, to: API_POST_ADD_POST)

                })

                upload.responseJSON { response in

                            if checkResult == 1
                            {
                                if let valueData = dictJson[resKey] as? NSDictionary
                                {
