Room and Organ Acoustic Measurements of St. Jakobus Church Ilmenau - Part 3: Recordings of Individual Pipe Tones

Description

This is part of a dataset of organ recordings and room acoustic measurements of St. Jakobus Church, Ilmenau. For an overview of the complete dataset, please refer to Room and Organ Acoustic Measurements of St. Jakobus Church Ilmenau.

To reproduce the organ sounds consistently, and to ensure perfect knowledge of the exact timing of every note played, an Orgamat was used - a device that is placed on top of the keyboard, can press the keys, and is controlled via MIDI. 
To facilitate a simple comparison with the room impulse response measurements, individual notes were recorded . 
Three registers were selected for this purpose and recorded both individually and in various combinations.
The registers were relatively easy to access inside the organ for miking and exhibit very different characteristics:

  • Register 1 Principal 16': One of the organ's main registers, with characteristic organ sound.
  • Register 4 Doppelflöte 8': Wooden, double-mouthed pipes with full, round tone.
  • Register 16 Scharff IV: 4 ranks of pipes with short scale and a bright, piercing tone.

All C notes across the entire manual were played and recorded individually and simultaneously in all combinations.
This was done for all three registers individually and in all combinations.
The notes were held for 2 seconds to give the pipes sufficient time to generate a stable sound, followed by 2 seconds of silence for the reverberation.
The same procedure was repeated for all B notes and for all F♯ notes on the manual, as this corresponds roughly to the middle of the octave.

The ZIP files contain the recordings of the respective tones, as well as the corresponding MIDI files.
Note: In the filenames, the german Fis was used for F♯ to avoid special characters.
