This covers distribution/aggregation services like, TuneCore, DistroKid, CD Baby, Indigoboom, Record Union, etc., and streaming platforms such as Spotify, iTunes, Apple Music, and TIDAL.
Currently, the safest format to use for digital distribution, aggregators, and streaming is a 16-bit 44.1kHz Wave file. While some say they accept any number of sample and bit rate combinations, what is not clear is how they are converting higher sample rates down to the streaming standard of 44.1kHz. At AudibleOddities, we use the best sample rate conversion currently available, and this will ensure your streaming masters sound their absolute best. Use the supplied 16-bit 44.1kHz master for these services.
If you’ve supplied your mixes at higher resolutions we’ll also provide a set of masters at their original bit-depth and sample-rate for archival, and for anywhere that supports high-res audio such as Amazon HD, Apple Digital Masters™, and Bandcamp.
