12. The system of claim 11 , the operations further comprising:

identifying a capability of a local device of the user; and

selecting a codec to perform the encoding of the output audio layer based on the capability of the local device.

13. The system of claim 11 , the operations further comprising converting an initial sample rate of the output audio layer to the determined output sample rate, wherein converting the initial sample rate to the determined output sample rate comprises (i) dropping one or more samples associated with the output audio layer in response to the initial sample rate being higher than the determined output sample rate, or (ii) duplicating one or more samples associated with the output audio layer in response to the initial sample rate being lower than the determined output sample rate.

14. The system of claim 9 , wherein the plurality of audio layers comprise a local audio input layer, an application audio layer, a system notification audio layer and a phone call audio layer.

15. The system of claim 9 , the operations further comprising:

storing, based on the first user input and the second user input, data identifying the two or more audio layers and data identifying the volume levels of the two or more audio layers.

16. A non-transitory computer readable medium comprising instructions, which when executed by a processor, cause the processor to perform operations comprising:

receiving first user input indicating a selection of a subset of two or more audio layers of a plurality of audio layers for media content to be provided to a user, each of the two or more audio layers corresponding to one or more audio sources;

receiving second user input indicating volume levels for the two or more audio layers of the plurality of audio layers;

capturing, based on the first user input, the two or more audio layers of the plurality of audio layers for a media content item to be provided to the user;
