The Blaze Media Pro software includes a powerful audio editor feature that can be used as a MIDI to MP3 converter, MIDI to WMA converter, MIDI to WAV converter, and MIDI to OGG converter. This is accomplished by recording the MIDI as it plays. To do so, click "Edit Audio" from the main interface. From the resulting window, you should select the input (volume) source from which you want to record (via a dropdown list located on the right-hand side of the audio editor window). The option to select for this setting will differ depending on your sound card. However, with most sound cards, it is named something like "What You Hear", "Wave", "Wave Out", or "MIDI Synth". Once you have selected the appropriate option, ensure that the "Select" checkbox is checked for this item. You are now ready to begin playback of your MIDI file in Media Player (or any other MIDI playback software) and record. With playback in progress, click the Record button on the audio editor window to begin. When the desired playback completes, press the Stop button on the audio editor window. Lastly, you can save directly to any desired format, such as MP3, WAV, WMA, OGG, MP2, or VOX. The saved file can now even be burned to an audio CD. which in turn provides a solution for converting MIDI to audio CD, or used as a ringtone for many cell phones, for example.
