Aspects disclosed in the detailed description include packetizing encoded audio frames into compressed-over-pulse code modulation (PCM) (COP) packets for transmission over PCM interfaces. In one aspect, a COP packetizing circuit is configured to receive an encoded audio frame generated from a PCM frame, and generate a COP packet that includes the encoded audio frame irrespective of the audio format. The COP packet is generated with a packet length proportional to a PCM length of the PCM frame, allowing the COP packetizing circuit to transmit the COP packet over an isochronous PCM interface with a lower bit rate than the PCM frame to reduce power. The COP packetizing circuit provides a mobile computing device with a single packetizing scheme that supports multiple audio formats, and allows for reducing power through bit rate scaling.

A particular apparatus includes a coder/decoder (CODEC) including a first processor and a first buffer. The first processor is configured to analyze audio data samples to detect a keyword. The CODEC is configured to store a set of audio data samples at the first buffer. The apparatus also includes an application processor configured to receive the set of audio data samples from the CODEC via a bus and configured to initialize a speech recognition engine (SRE) based on the set of audio data samples. The application processor is configured to initialize the bus based on an indication from the CODEC that the keyword is detected.

A method and system for played a mixed audio in a communications device during an active communication session is disclosed. One configuration allows for ringtone audio to be heard simultaneously with voice audio received during an on-going phone call. In one configuration, the device comprises a transceiver a transceiver configured to receiver a first audio signal, an event handler configured to receive a notification, a storage configured to store at least one audio file, a processor configured to initiate a conversion of an audio file stored in the storage into a second audio signal, based on the received notification, a mixer configured to mix the first audio signal and the second audio signal to create a mixed audio signal, and an output device to output the mixed audio signal.
