Audio meters and parameter controls

Abstract

Some embodiments provide a media editing application that displays the audio level of a set of one or more clips that has been mixed with other clips. To indicate the audio level of the set of clips that has been mixed with other clips, the media editing application of some embodiments routes a combined audio signal of the set of clips over a meter bus in order to determine the audio level of the combined audio signal. Alternatively, the media editing application of some embodiments extracts metering information from each clip in a set of clips prior to mixing the clips. The metering information is then used to estimate the audio level of one or more clips in the composite presentation.

Description

CLAIM OF BENEFIT TO PRIOR APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application 61 / 537,041, filed Sep. 20, 2011, and U.S. Provisional Application 61 / 537,567, filed Sep. 21, 2011. U.S. Provisional Application 61 / 537,041 and U.S. Provisional Application 61 / 537,567 are incorporated herein by reference.BACKGROUND[0002]To date, many media editing applications exist for creating a composite media presentation by compositing several pieces of media content such as video, audio, animation, still image, etc. In some cases, a media editing application combines a composite of two or more clips with one or more other clips to output (e.g., play, export) the composite presentation.[0003]There are a number of different problems that can occur when outputting such a composite presentation. For example, some movie studios require a particular content (e.g., dialog content, music content) of a composite presentation to be separate from other content. The content separ...

Benefits of technology

[0009]Different embodiments provide different schemes for specifying one or more effects to apply to media content that have been associated with a metadata tag. For instance, in some embodiments, the media editing application allows an effect chain or an effect list to be specified for each type or category of metadata tag. In some embodiments, the media editing application allows its user to specify effect properties for the effects in the effect list. These effect properties define how the corresponding effect is applied to the media content.

[0010]Based on metadata associated with different clips, the media editing application of some embodiments applies a set of effects (e.g., echo effect, reverb effect) by using a “send” or a “send and return”. In some embodiments, the “send” is performed automatically such that the routing of audio signals of the different clips to an effect module is transparent to the application's user. That is, the user does not have to add an input auxiliary (“aux”) track, specify an effect for the aux track, specify an input bus for the aux track, create the “send”, and identify the specified bus to route the audio signals of the different clips. Instead, the user can simply specify a particular effect for a metadata tag. The media editing application then applies the particular effect using the “send” to a combined audio signal of each clip tagged with the meta

Problems solved by technology

There are a number of different problems that can occur when outputting such a composite presentation.

The problem with providing separate content is that, once several pieces of media content are mixed as one mixed content, the mixed content cannot be un-mixed to provide the separate content.

However, the “send” techniq
