IZOTOPE OZONE 8 REFERENCE TRACK HOW TO
We'll explore what this might look like in practice, and how to identify lossy audio in a spectrogram. While this won’t conclusively prove that a mix was encoded with a lossy codec, artifacts from a lossy codec will be evident visually in your spectrogram. The signature of the beat’s MP3 lossy codec is likely to appear in your spectrogram display. Why does this matter? Let’s say, for example, the mix you were sent included an MP3 beat and an AAC vocal file.

So how can you tell if lossy artifacts appear in your track? Sometimes seemingly full resolution files-WAV, FLAC-or even pieces of a full resolution file, may once have passed through a lossy codec. H ow to tell if your reference track contains lossy artifacts using a spectrogram and Ozone Codec Preview If you send your master to a streaming service for distribution, those artifacts may be compounded if loudness normalization is employed by the service. When you compare your work against a lossy reference track, your reference will be slightly skewed because the lossy codec created some artifacts. However, these codecs do create artifacts that, while seemingly hard to detect, change the overall tone and add distortion to what you hear. All the different lossy audio codecs used by major distribution services- MP3, AAC, Ogg Vorbis-are used so that it’s easier for your listeners to hear your music.
The quality of your reference track’s audio is very important. The importance of mastering reference track audio quality This is why you want to ensure you have loudness normalization turned off on these services, if you must use a streamed reference track, so you can truly understand what is ultimately going to happen to your master once you’re finished. You may notice variation depending on low end energy, how much compression there is, and other factors, but in general with loudness normalization on, you won’t get gross differences in terms of level between tracks.īy changing the level at all, if you use that track as a reference for your mastering work, you’re not really comparing it to the level of the master-you’re comparing it to the level of the loudness-normalized streamed track. Streaming services use loudness normalization to make sure the playback level is more or less consistent between songs.
Yes, music streaming services-the main supplier of the audio we listen to-sometimes modify the audio to give consumers a better listening experience. Do you know where your reference tracks have been?ĭon’t be fooled by the audio you hear from a streaming service-platforms like Spotify and Tidal have loudness normalization on by default, and some services only allow for normalization on desktop and not mobile. To do this, you need to be able to hear, as closely as possible, the song’s audio the same way it came off the mastering desk-not changed by a distribution service, not changed by cutting it to vinyl, putting it on cassette tape, or converted to MP3 or AAC. When you use a reference track in mastering, your main goal is to accurately compare your work to what’s out there in the world-your favorite recordings or the production decisions that define the genres within which you’re working.
