Audio content production, audio sequencing, and audio blending system and method

An audio blending method comprising:

• providing a computing device comprising at least one processor;
• providing a non-transitory computer readable medium, having stored thereon, instructions that when executed by the computing device, cause the computing device to perform operations comprising:
• receiving a transition request, the transition request comprising at least one of an out element and at least one of an in element of at least one transition associated with at least one content item of at least one recipe, the at least one recipe comprising a sequence of a plurality of elements of content of a break and the at least one content item, the at least one content item comprising at least one of audio content and video content;
• causing a track server to couple to at least one metadata file of at least one audio file using a wired or wireless link, the metadata file comprising audio content parameters measured or calculated from the at least one audio file;
• calculating a transition between the at least one out element and the at least one in element;
• selecting, assembling and scheduling the sequence of plurality of elements for the transition;
• determining fade out content of the at least one audio file based on an amplitude, wherein operations identifying a type of fade as smooth or rhythmic are based at least in part on at least one of duration and amplitude;
• and
• adding the out element and fade out content to the at least one recipe.
