Sending Vocals to the Engineer
When sending the audio containing the vocals to the engineer, there is some steps to take to ensure that everything run smoothly. First, always send the audio in WAV format. Other lossless format are also a good alternative but Wav is the most common of them. If you decide to send an mp3 file instead, the software processing made to the sound by the engineer will result in an even greater loss in quality than the one previously applied by the existing compression made from rendering said mp3. As seen in the picture below, the first thing to do is to keep the vocals in sync with the whole instrumental. This will be achieved by leaving the silence before and, optionally, after the audio for every layer recorded. This will keep the audio from having to be synced back to the whole mix. Most softwares are able to do so when exporting the tracks. Don’t worry about the increase in file size since the next step will be to send all audio in a .rar or .zip archive. This step is optionnal if you only have one wave file but if you have more than one audio track, it will keep the files organised and make the data transfer faster and way easier. Also note that it is better to leave the vocals without any effects applied. Those will be selected while mixing the whole song and having them already hardcoded on the vocal tracks will most likely cause more harm than good to your project or to the engineer’s time. They will also sound a lot better if they are applied while mixing the song and more artistic effects can always be requested while sending the files.
