Abstract
Some aspects of the present disclosure involve the recording, processing and playback of audio data corresponding to conferences, such as teleconferences. In some teleconference implementations, the audio experience heard when a recording of the conference is played back may be substantially different from the audio experience of an individual conference participant during the original teleconference. In some implementations, the recorded audio data may include at least some audio data that was not available during the teleconference. In some examples, the spatial characteristics of the played-back audio data may be different from that of the audio heard by participants of the teleconference.
Claims17
An apparatus, comprising:
- an interface system;
- and
- a control system configured to perform operations comprising:
- receiving teleconference audio data during a teleconference, via the interface system, the teleconference audio data comprising a plurality of individual uplink data packet streams, each uplink data packet stream corresponding to a respective telephone endpoint, each telephone endpoint being used by one or more teleconference participants, at least one of the uplink data packet streams corresponding to a particular telephone endpoint being used by multiple teleconference participants and including spatial information regarding each of the multiple teleconference participants, the spatial information comprising information for rendering each of the multiple teleconference participants to a respective virtual conference participant position in a virtual acoustic space;
- and
- sending to a memory system, via the interface system, the teleconference audio data as individual uplink data packet streams.
A method of processing audio data, comprising:
- receiving, via an interface system, teleconference audio data during a teleconference, the teleconference audio data comprising a plurality of individual uplink data packet streams, each uplink data packet stream corresponding to a respective telephone endpoint, each telephone endpoint being used by one or more teleconference participants, at least one of the uplink data packet streams corresponding to a particular telephone endpoint being used by multiple teleconference participants and including spatial information regarding each of the multiple teleconference participants, the spatial information comprising information for rendering each of the multiple teleconference participants to a respective virtual conference participant position in a virtual acoustic space;
- and
- sending, via the interface system, the teleconference audio data to a memory system as individual uplink data packet streams.
A non-transitory medium having software stored thereon, the software including instructions for processing audio data by controlling at least one device for:
- receiving teleconference audio data during a teleconference, the teleconference audio data comprising a plurality of individual uplink data packet streams, each uplink data packet stream corresponding to a respective telephone endpoint, each telephone endpoint being used by one or more teleconference participants, at least one of the uplink data packet streams corresponding to a particular telephone endpoint being used by multiple teleconference participants and including spatial information regarding each of the multiple teleconference participants, the spatial information comprising information for rendering each of the multiple teleconference participants to a respective virtual conference participant position in a virtual acoustic space;
- and
- sending the teleconference audio data to a memory system as individual uplink data packet streams.
