Whenever you need a tool to convert RM format to MP3 audio files, you can use Fast RM to MP3 Converter. It comes as an easy-to-use tool that, contrary to its name, handles a lot of audio formats, such as: MP3, OGG, WAV, RM, AAC, AMR, WMA, etc. This program doesn't require many system resources (CPU, RAM, etc.
Fast RM to MP3 Converter doesn't bring anything new to the table. It is a program similar to many other available, but it does its job well. A thing I didn't appreciate is that the application doesn't offer access to settings. The only thing that you are allowed to customize is the audio profile for the output file. No user-interface customization is available.
I tested Fast RM to MP3 Converter by using an audio file in RM format but it failed to convert it to MP3 format. I tried again with a WAV file and managed to convert it to MP3 format. Although, this application supports batch conversion, the trial version will allow you to convert only one audio file at a time.
Fast RM to MP3 Converter is an application like many others of its kind. It’s worth a shot, in my opinion.
