First Church of Christ Scientist, Darlinghusrt

What is this? Where are the samples?

This project is a trial to create a sample set using a collaborative approach. This page will provide the recordings where were made on-location by me. 4 channels of microphone data were recorded: 2 were made using spaced omni-directional large diaphragm condenser microphones and 2 were made from a somewhat closer XY configured small-diaphragm spaced pair. I have mixed down the tracks to stereo and applied equalisation to provide the tonality which I think works well for the instrument. These recordings need to be noise-reduced, chopped up, looped and for an organ definition file to be created. The audio downloads will be supplied on a per-rank basis. Once the processing has been completed on an entire rank, pop me an email and I will give instructions on how to give me the completed work which I will then place on this website.

If you would like to contribute to this project, please send an empty email to x@y (where x = “firstchurch-join” and y = “”). This will subscribe you to the mailing list for this project where you can ask questions and state your intentions to work on ranks – this is helpful as we can keep track of who is working on what to avoid un-intentional overlaps. I will list beside the downloads the initials of all users working on particular ranks. The email address of the mailing list is x@y (where x = “firstchurch” and y = “”) and is where generic questions can be directed. You can also use the comments box on this page if you do not want to join the mailing list.

All downloads will be supplied via bit-torrent. I am doing this as there is a tremendous amount of data which I will have to distribute from my own internet connection. There are bit-torrent clients available for all operating systems (Vuze [Windows, Linux, Mac], Transmission [Linux, Mac] don’t contain spyware). You can help this project massively by ensuring that your bit-torrent client can be accessed from outside connections (if you don’t know what this means, don’t worry) and leaving the bit-torrent client open for as long as possible after the download completes. This will help reduce the amount of bandwidth I need to supply and will ensure faster downloads for everyone who tries to obtain these files.

General Organ Information

The organ of First Church was built in 1925 by Australian organ builder J. E. Dodd, rebuilt in 1935 by Whitehouse Bros of Brisbane and overhauled in 1979 by Pitchford and Garside of New South Wales. It is a 3 manual 39 stop instrument with many orchestral qualities. The organ is located at the front of the auditorium behind a screen in an elevated section of the building made for the organ.

I was contacted by the organist earlier in the year asking if there was anything that could be done to preserve the sound of the organ – as the building had been purchased by a private owner to be turned into a residence – as a result, these recordings were made over several weeks.

    Hi Nick !!!

    Got the Great Open Diapason 8′ for editing.
    Torrent worked OK.
    Recording is good. Yep, needs hard NR 🙂
    Thanks for this !
    I’ll get back when I’ll be with an example rank ready.

      1. Panos Ghekas

        Hi Nick, It’s No.1

        I listened again… it’s OK. I think I can work something out of it.
        I haven’t started yet 🙁 as I have to finish some other organ set projects during September . Then I’m diving in !
        If earlier, I ‘ll start first with NR and I’ll post here asap .

        Should I go for No.2 ? Do you need me to get another stop?

        1. nick Post author

          The No. 2 is the main chorus diapason.

          The No. 1 is a louder diapason which can be used solo or to add more power to the full chorus. It would probably be good to start with No. 2 if you have it.

  2. Panos Ghekas

    Nick…… no joy…
    μ-torrent says : “Tracker sends wrong data : ”
    waited many re-fresh/re-loads, no work.
    Why wrong data ?
    Strange because I got No.1 end of June with the same version , slowly but OK.
    I’ll update the software, as it says “stable new version ready” and see what happens.
    If not , I’ll try your recommendation, though I’m use to μ-torrent for some years now LOL

    Hi Nick,

    I’d be interested in helping out with this project. I’ve downloaded a few of the ranks, but haven’t had much luck with noise reducing them. I’ve tried your utility as well as some others without much success. I don’t have much experience with this, so perhaps I’m just not using your noise reduce software as well as I could be. That being said, if somebody else did the noise reduction, I could split the files up and loop them. Let me know if this would be something you’d be interested in. I’d love to see this project get off the ground!

    All my best,

      Hi Matt,

      Thank you for your interest in the project.

      There is a possibility that the recordings are simply too noisy to be processed (with the currently available noise reduction software anyway). Although being a very fine instrument, the organ was old and had leaks in the bellows. I did place blankets near the noisy areas but this only had a limited effect. The louder ranks are going to be simpler than the soft ranks.

      Perhaps some of the other guys have had some luck? You could try sending an email to the mailing list.

      1. Matt W.

        Well, I’m sorry to hear that there’s a chance that the project won’t work out as well as it might have. From looking at the specification it sounds like, as you said, that it was a really interesting instrument. I am glad to know, however, that I’m not the only one that has been having trouble reducing the level of the noise in the files. Are there some ranks which are particularly loud that might be worth trying to noise reduce (I’d guess the one labeled as high pressure. Any others?). If those ranks are successful at least we would have something. Also, if I was going to send an email to the mailing list, would I send it to the same address listed above for requests to join the mailing list? If so, I may give that a shot. If not, where should I send the email?

        I hope that you’re doing well and look forward to hearing back soon.

        Take care,

    Hi 🙂

    Though I’m familiar with NR I still cannot download any of the rest of the ranks except the 1st OpDiap one…. (?)
    I have to finish some project I’m involved and then I’ll start with what I’ve got so far and post here or better on the list.

  5. Panos Ghekas

    Hi Nick !
    I’m getting it now as I type this ! Yes. M-Torrent says in about an hour and a half it will be full here.
    I’m de-noising two other sampled organs these days, so OpDiap2 will be in the row… I’ll probably bring it first, as I feel I owe to it !! LOL

    It has very strong low-frequency noise component which removing makes sound very dull, especially on soft registers like dulciana.

    1. nick Post author

      Hi Roman,

      Yes, the samples are very noisy and difficult to work with. I am working on tools to help with this but they are not ready for release yet.


  7. Roman

    Nick, it is possible to do SOMETHING. But how it will sound i don’t know yet.

    I’ve lost almost all low-volume transients like opening and closing of loud flutes (I mean not the musical tone itself but that specific noise). I’ve lost ending part of reverb tails. But it is recoverable too – pipes recorded quite nearly so some reverb will help and make more pleasant sound.

    Anyway, organ has very specific sound. So it will be interesting even with this quality.

  8. Roman

    I think it will have similair quality to St. Anne of Hauptwerk 2 – too denoised and dry. And special question is mixtures. May be it should be reconstructed from other registers or even other organs.
