無料オンラインRMからOGGへのコンバーター

RM is a proprietary video container created by RealNetworks Inc. - the pioneers in streaming media over the internet market. This format supports DRM and was widely used to stream video and audio data online in the early 2000s with more than 80% of online streaming was in the RealMedia format. RM is supported by iPhone, Android, Windows and Mac. This container is often used by online radio stations. Nowadays it is still necessary to install Real Player plugin to be able to play RM files on such streaming websites.

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.
