Like others on these forums, I am considering trying my hand at creating a sample set. I have some realization of the magnitude of the task. I also have little experience in recording, and have struggled to understand some of the advice I've read on the forum. But I do have some experience with basic sound processing in Audacity, I am comfortable with command line tools and XML, and I have some local contacts who can probably help me with mics and recording. So I'm going to experiment and see how far I can get.
As I understand it, the process works like this:
1. Record organ samples, one rank and note at a time.
2. Denoise the samples and chop them into individual wav files.
3. Add info to each wav file to indicate locations of the loop and release point, and the recorded pitch.
4. Create an ODF or CODM-format XML file.
Could someone give advice as to the most efficient way to do this? For example, I was thinking of trying this approach:
1. Record each note of a rank, one after the other, in a wav file
2. Denoise the wav file (using Nick Appleton's Noise Reduce software)
3. Chop the file up into separate wav files for each note
4. Add markers to each wav file to indicate the loop point and release point
5. Add tuning info to each wav file (using the Hauptwerk Stop Prepare tool?)
Here are some questions:
I am fuzzy on how to add markers to the wav files to indicate loop and release points. I've read about Nick Appleton's Autoloop software, and am planning to try it out on adding loop points, but it doesn't appear to be able to add release points. I am planning to use Audacity to do much of my editing, but it does not appear to support editing loop / release points. I was thinking that if I hold each key down for the same length of time, that it should be possible to automate inserting the release point (at least getting it in the ballpark). Can someone recommend a free tool for this purpose?
Also, can anyone recommend a free tool to automate chopping the file up into separate wav files for each note? I would think that, after denoising a wav file, silence detection could be used to do this. Thoughts?
I've seen references to using the Hauptwerk Stop Prepare tool to autodetect the pitch of a note. Does it perform any other functions?
Have I missed any significant steps or points? I wish Charles Braund's guide were available!
Update: Charles's guide is available. I just ordered it from him and am looking forward to reading it.
Thanks in advance for your help.
