Create your release as usual but do not upload your audio files.
Inform your Label & Artists Support Specialist that you wish to upload HD audio files. In your e-mail, please inform the release title and UPC, as well as the quality of the audio you wish to upload:
|24/44 audio quality|
|24/48 audio quality|
|24/88 audio quality|
|24/96 audio quality|
|24/192 audio quality|
Once you’ve received a confirmation by e-mail that your HD option is activated, you can proceed with the audio upload.
Please note: You must use the same audio format for the totality of the tracks. Not all stores accept HD audios (currently only Qobuz, Apple, 7 Digital, High-res audio), so your release will be distributed as HD to those who are able to support this format and as 16 bits to the others.
If you're encountering any issues with this subject, please contact your Labels & Artists Support team. If you don’t know which support address to use, check the full list here.
