We can take care of your online audio mastering at the time of your CD mastering session and supply you with the format you require (Note: some sites, such as SoundCloud, stream audio at reduced mp3 quality, while if you to make your tracks downloadable this will be at whichever format you upload, such as CD quality wav files or, better still, lossless FLAC from the full-resolution 24 bit/native sample rate mastered files).
For making your music purchasable online (such as the iTunes store) each of your tracks, including each version or mix of a track, will need an ISRC (International Standard Recording Code). In Australia these are overseen by ARIA – the Australian Recording Industry Association. See here for ISRC information.
If you have your ISRC’s at the time of your mastering session, it’s no problem for us to embed them into your Production Master and, hence, your replicated CD’s.
