Abstract
Methods (700, 800, 900), systems (200, 300, 400, 500, 600) and computer program products are provided. Location metadata (620) associated with an audio object is received (801). The location metadata defines a position of the audio object in an audio scene. It is estimated (630, 802), based on the location metadata, whether the audio object includes dialog. A value representative of a result of the estimation is assigned (803) to an object type parameter (231). In some example embodiments, audio objects are selected (661, 662, 804) based on values of their respective of object type parameters. In some example embodiments, at least one of the selected audio objects is submitted to dialog enhancement (690, 807).
Claims14
A method comprising:
- receiving location metadata associated with an audio object, wherein the location metadata defines a position of the audio object in an audio scene;
- estimating, based on the location metadata, whether the audio object includes dialog;
- and
- assigning a value to an object type parameter representative of a result of the estimation,
- wherein estimating whether the audio object includes dialog comprises:
- computing a speed of the audio object based on location metadata associated with different time frames;
- and
- estimating, based on said speed, whether the audio object includes dialog.
A computer program product comprising a non-transitory computer-readable medium with instructions, which when executed by one or more processors of an electronic device, cause the device to perform the steps of:
- receiving location metadata associated with an audio object, wherein the location metadata defines a position of the audio object in an audio scene;
- estimating, based on the location metadata, whether the audio object includes dialog;
- and
- assigning a value to an object type parameter representative of a result of the estimation, wherein estimating whether the audio object includes dialog comprises:
- computing a speed of the audio object based on location metadata associated with different time frames;
- and
- estimating, based on said speed, whether the audio object includes dialog.
A system configured to receive location metadata associated with an audio object, wherein the location metadata defines a position of the audio object in an audio scene, the system comprising:
- a processor configured to perform the following:
- estimating, based on the location metadata, whether the audio object includes dialog, and
- assigning a value to an object type parameter representative of a result of the estimation,
- wherein estimating whether the audio object includes dialog comprises:
- computing a speed of the audio object based on location metadata associated with different time frames;
- and
- estimating, based on said speed, whether the audio object includes dialog.
