Can Java save MIDI to WAV file?

[David Koelle]

When MIDI is played in Java, the Synthesizer converts MIDI messages into actual musical sounds based on the instruments/soundbanks it has loaded.

If you save and play the MIDI itself in a different media application (e.g., WinAmp), it may sound different because the application does not necessarily load the same soundbanks as the Java synthesizer.

Is there a way to get Java to save the actual audio generated by the Synthesizer into a WAV file, or some other audio encoding?


Thanks!

Currently Java Synthesizer doesn't support writing directly into audio file. The audio has to be recorded
through the line-in on your sound card.

But Gervill Synthesizer for Java does supports writing directly to audio file. https://gervill.dev.java.net/
And it has support for both SF2 and DLS soundbanks. A Midi2WavRender.java is included in the src.demos.

Karl

Hi,

Frinika (frinika.sourceforge.net) does this by playing the sequence one tick at a time -> sending midi events to the synthesizer (in your case I would use Gervill, rather than java default synth, since it's easier to get hold of the audio output) -> read the audio output produced from the synth - and write it to the wav file.

The core stuff is happening here:

http://frinika.svn.sourceforge.net/viewvc/frinika/frinika/trunk/src/com/frinika/tools/MyMidiRenderer.java?view=markup

But you probably need to browse the code a little more to get the whole picture.

This is part of the "Export wav" function from the "file" menu in Frinika.

cheers,

Peter
