Adapting audio streams for rendering

A method of playing one or more of a plurality of audio streams, the method comprising:

• storing, by one or more processors, a plurality of audio streams, each of the plurality of audio streams representative of a soundfield and include one or more sub-streams;
• determining, by the one or more processors and based on the plurality of audio streams, a total number of the one or more sub-streams for all of the plurality of audio streams;
• adapting, by the one or more processors and when the total number of the one or more sub-streams is greater than a render threshold indicative of a total number of sub-streams a renderer supports when rendering the plurality of audio streams to one or more speaker feeds, the plurality of audio streams to decrease the number of the one or more sub-streams and obtain an adapted plurality of audio stream including a reduced total number of the one or more sub-streams that is equal to or less than the render threshold;
• applying, by the one or more processors, the renderer to the adapted plurality of audio streams to obtain the one or more speaker feeds;
• and
• outputting, by the one or more processors, the one or more speaker feeds to one or more speakers.

A device configured to play one or more of a plurality of audio streams, the device comprising:

• means for storing a plurality of audio streams, each of the plurality of audio streams representative of a soundfield and include one or more sub-streams;
• means for determining, based on the plurality of audio streams, a total number of the one or more sub-streams for all of the plurality of audio streams;
• means for adapting, when the total number of the one or more sub-streams is greater than a render threshold indicative of a total number of sub-streams a renderer supports when rendering the plurality of audio streams to one or more speaker feeds, the plurality of audio streams to decrease the number of the one or more sub-streams and obtain an adapted plurality of audio stream including a reduced total number of the one or more sub-streams that is equal to or less than the render threshold;
• means for applying the renderer to the adapted plurality of audio streams to obtain the one or more speaker feeds;
• and
• means for outputting the one or more speaker feeds to one or more speakers.

A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, cause one or more processors to:

• store a plurality of audio streams, each of the plurality of audio streams representative of a soundfield and include one or more sub-streams;
• determine, based on the plurality of audio streams, a total number of the one or more sub-streams for all of the plurality of audio streams;
• adapt, when the total number of the one or more sub-streams is greater than a render threshold indicative of a total number of sub-streams a renderer supports when rendering the plurality of audio streams to one or more speaker feeds, the plurality of audio streams to decrease the number of the one or more sub-streams and obtain an adapted plurality of audio stream including a reduced total number of the one or more sub-streams that is equal to or less than the render threshold;
• apply the renderer to the adapted plurality of audio streams to obtain the one or more speaker feeds;
• and
• output the one or more speaker feeds to one or more speakers.
