Giveaway of the Day - free MP3 conversion software
Hi friends,

A personal post here (not an official Notation Software UG post).

"Giveaway of the Day" is - for the next 16 hours - offering "MP3 Toolkit 1.1" free as part of their daily giveaway program. This software will convert WAV files to mp3 (I've just tested it successfully), so that you can convert the .wav files that you can export with Notation Composer 3 into mp3 files if you want.

Please note that this software typically is a "pay for" program because of the licensing fees for mp3 technology. Giveaway of the Day is a promotional website designed to give software developers a way to let folks get a free license for a short period of time in order to promote their software.

If you would like to check this program out, you can visit their website at

Sherry, thanks for this post.

Some people may ask "Why does Composer not export audio files in mp3 format in addition to the WAV format?"

This is a good question. We, of course, considered this feature as part of the version 3.0.3 but finally decided not to offer it. The reason is that the mp3 format is patent protected. There is the great open source software of Lame available which many applications like this mp3-Tool-Kit use. However, this is not fully legal and is patent infringing in countries which recognize those patents. The Lame developers do not own a patent and consider Lame as " educational description and study of an MP3 encoder." For more see here. Because our customers are all over the world we decided not to include this feature in Composer. The costs for the use of those patents in our products would are beyond any reality.

In 2017 all patents for mp3 expired. We therefore decided to add .mp3 audio export into Composer 3.0.7

In Composer 3.0.7 comes with the following audio exports formats
  • mp3
  • Wav
  • Ogg
  • Flac

Thank you, Reinhold! That will save a conversion step that I have used fairly frequently when sending mp3 files to my friends.
