無料オンラインTSからOGGへのコンバーター

TS is an extension defined by MPEG-2 standard. It is usually used for storing video and audio on DVDs, for streaming media online and broadcasting. This media container consists of elementary streams stored in a way that allow quick playback resume and audio/video synchronization after an error in data transfer was encountered.

This format is free, which apparently is one of the reasons for its popularity. The used codecs supports variable bit rates (as a default), and .ogg files usually play back easily on all platforms. All things being equal, the sound quality exceeds that of mp3 somewhat.
