If you do podcasting on a Windows PC, you’ll find AudioShell extremely useful.
AudioShell is a freeware Windows Explorer shell extension plugin which allows you to view and edit music file tags directly in Windows Explorer. It adds tag editor and viewer tabs to the properties page of music files. You can edit tags file by file or by groups, and it gives you detailed tag and file information and additional columns in the Explorer files list.
I’ve been using it since its beta launch last month. Of course, you can use this plugin for editing the tags in many music file formats, not only MP3 podcasts.
Supported files and tags formats: mp3 (all ID3v2 tag versions), wma, asf and wmv, Apple iTunes aac (m4a and m4p) and mp4 files, ogg, flac (vorbis comment tags), mpc , mp+, monkey’s audio, wav pack, optim frog ( APE and APEv2 tags).
AudioShell version 1.0 has just been released. Available now on free download.
