Techniques are provided for implementing multi-track audio analysis. In some instances, a plurality of audio tracks are received and combined into a single audio file. A collection of audio file characteristics are extracted from the single audio file. In some examples, the collection of audio file characteristics are associated with of the plurality of audio tracks and the single audio file. Audio characteristic edits are received for revising the collection of audio file characteristics. Metadata associated with each of the plurality of audio tracks and for the single audio file are updated based at least in part on the audio characteristic edits.

There is provided an information processing device, a generation method, and a program that are capable of editing or reproducing a lecture-containing video in an appropriate form. The information processing device includes a generation unit configured to generate information for reproduction assistance, depending on importance levels each determined for one of predetermined sections generated by dividing data including a video and a sound of a lecture. The importance levels are determined on the basis of information associated with the lecture. The present technology can be applied to, for example, a lecture capture system used for imaging a lecture.
