To update the metadata of a song we can do by using ID3 tags. We can update these using Mp3Tag editor - https://github.com/aminb/id3r , MyID3() editor - https://github.com/ericfarng/jid3lib and Jaudiotagger - https://github.com/Adonai/jaudiotagger.

Mp3Tag editor - Only Mp3 song type is supported MyID3 editor - Can edit song easily but not all field provided is updated Jaudiotagger - This supports Mp3, Flac, OggVorbis, Mp4, Aiff, Wav, Wma, Dsf audio formats It updated data without any issue

try {
      val audioFile = AudioFileIO.read(file)
            val tag = audioFile?.tagOrCreateAndSetDefault
             tag?.setField(FieldKey.ARTIST, binding?.tiArtist?.text?.toString())
            tag?.setField(FieldKey.ALBUM, binding?.tiAlbum?.text?.toString())
            tag?.setField(FieldKey.GENRE, binding?.tiGenre?.text?.toString())
            tag?.setField(FieldKey.TITLE, binding?.tiTrack?.text?.toString())

            // Handle the image setting
            try {
                    val pfd = contentResolver.openFileDescriptor(imageUri, "r") ?: return

                    val fis = FileInputStream(pfd.fileDescriptor)
                    val imgBytes = JavaUtils.readFully(fis)
                    val cover = AndroidArtwork()
                    cover.binaryData = imgBytes
                    cover.mimeType = ImageFormats.getMimeTypeForBinarySignature(byteArray)
                    cover.description = ""
                    cover.pictureType = PictureTypes.DEFAULT_ID
                    tag?.deleteArtworkField()
                    tag?.setField(cover)
                    fis.close()

              // to do check the file write option for both internal and external card
             // Handle the Storage Access FrameWork API if song is from SD card
            if (audioFile?.file?.let { SafUtils.isSafNeeded(it, this) } == true) {
              // Handle writing into SD card
              // Check if SAF permission is provided then only we can update metadata 
             // If SAF Permission is not provided. EACCESS : Permission Denied error is displayed 
            // After the permission success then only we can update meta.
                 writeIntoSDCard()
            } else {
                // Handle writing into internal card
                writeInInternalStorage()
            }
         } catch (e: Exception) { }
        } catch (e: Exception) {
            // Show error on failure while writing
        } catch (e: Error) {
            // Show error on failure while writing
        }      

Writing the metadata

// After update refresh the file else the changes will not be reflected
AudioFileIO.write(audioFile)
MediaScannerConnection.scanFile(context, arrayOf(file?.absolutePath ?: ""), null, null)
