Second streaming test, with sound directly from Hauptwerk ánd a microphone for talking

Three days ago I performed my "first live stream". It was more of a test than a real concert. I wanted to try whether I could combine the sound from Hauptwerk directly into a live video stream (instead of capturing with the microphone of the video camera the sound coming from speakers). And I succeeded in doing that. You can read more about that here: https://peakd.com/classical-music/@partitura/first-streaming-test-with-hauptwerk-sound.

Now, the next step is to bring in a microphone into the setup. It would be nice if I could make short introductions before I play something. For Hauptwerk I use ASIO4ALL as sound driver, meaning the Windows sound system is not available. Therefore I can not simply plug in a microphone into my desktop and expect it all to work. I need a way to connect the microphone to my desktop in a way that the sound driver ASIO4ALL can pick it up.

Luckily, I have yet another external sound card, the MOTU Audio Express. I bought that, and the microphone by the way, to measure the audio characteristics of my music room, in order to apply room correction to the sound of Hauptwerk coming from my speakers. Room correction is a necessity for any Hauptwerk player, as it smooths out the ugly effects like interferention and standing waves any room has on sound coming from speakers.

The microphone is one from SonarWorks, the company I bought the room correction software from. Until now I have used it only to measure my music room. And I've only done that twice. So it is nice to have something else to use it for.

It took a bit of fiddling around to work out how I could get the sound from the microphone into Reaper. Once that worked, it was a matter of combining the sound from Hauptwerk with the sound from the microphone and send it to the videoatream in the way I already had worked out for the sound of Hauptwerk alone.

I positioned the microphone on the organ so it can pick up my voice when I sit on the organ bench. And after that it was time to play some pieces live to test it all.

The microphone is of when I play. Otherwise it would pick up al the noice from playing, and perhaps the organ sound from my headphones as well, thus creating a feed back loop. The sound has a little lag between being recorded by the microphone and played back on my headphones. I have to put the headphones of when I talk, otherwise I hear myself with a lag of about half a second. And it's not easy talking that way, I can assure you.

The 'program' of my live stream consisted of three compositions:

  • Anonymus, Da Jesu an dem Kreuze stund
  • Johann Sebastian Bach, Sinfonia from cantate BWV 106
  • Johann Schneider, Präludium und fuge, g moll

The first minutes of the video are silent, I forgot to turn on the microphone. Silly, mistake. Other than that little mistake, the microphone works perfectly, and I can make little introductions before each piece I play.

Playing live is still a challenge. There are several little misatkes in my performance and one rather large one in Schneider's prelude. Luckily I manged to pick it up again without interupting the flow.

The stream is still available to watch:

And now my youtube channel features no less than two live streams. Yeah... 😃
