I have lots of podcasts and online radio recordings, mostly interviews, talk programs about a wide range of topics. I would like to somehow index or categorize them and for the purpose I'm looking for a portable freeware. Requirements below.
- Ease of putting on time markers (with a keyboard shortcut) and annotate them with custom text.
- Supports creating subtitle-like timed transcripts for each file which can be actively displayed during playback. Supports search in all of these transcripts at once.
- Automatic transcripting based on voice recognition would be a big advantage, however I highly doubt if there's anything like that in offline software, so this is not a must.
- Can tag each recording and can search for these tags among all recordings. Tags should be user-specified (e.g #climatechange #technology #science).
- Basic editing features, possibly without re-encoding (like in mp3DirectCut). It's also good if it can launch an external application with the ease of a click (or a keypress).
- Can detect, jump through silent parts in a recording with a keypress.
- Still compatible with Windows XP (SP3 is enough).
