I have a question about Gold Wave in regards to editing samples for midi instruments (soundfont format, sfz, etc.)
For those unfamiliar with this, you can basically load an instrument in this format into a compatible player and it will respond to midi. Play a note and the instrument will play that note, release the key and the instrument sound will be stopped. There are obviously many parameters that can be controlled, but that's the basics and is all that is important for this thread.
Some of the samples I make need to be looped. The way loops work in such an instrument is that you set a start and end loop point, often in samples. While holding a key, a sample will play until it reaches the end loop point, then wrap back around to the start and will go to the end before wrapping back around to the start again, and will just keep doing that ad infinitum until you release the key.
What I often have to do is find or sometimes create good-sounding loop points. As I said above, loop points are often specified in samples, which Gold Wave fortunately can work with directly. But it cannot insert loop points into a wav header. So I have to remember the start and end values and stick them into another program. While remembering loop points and putting them down in another program is doable, it is a pain. If I could set loop points at marker positions, that would be the bulk of what I need, as well as obviously the ability to see and edit existing loop information in a file.
Just to give some context, the free Wavosaur audio editor supports loops and it is not a sampler. While it supports additional sampler info (for instance sample note, loop mode etc.), it cannot actually make use of that on its own. The only thing I use it for at the moment is inserting loop points. So I see little reason to withhold suggesting that it could be in Gold Wave in some basic form.
Features that would be useful:
Ability to not only move the loop points individually, but lock the length and move both points at the same time.
Ability to set the start or finish marker to the start or end loop point.
setting loop mode to normal or bidi (the latter plays the loop forward then backward). Not necessary, but could be useful for some samplers which support it. Don't know of any free/cheap audio editor that supports this, and there are only a couple modern sample players I know of that do, so this is rather low on my list.
Come to think of it, Gold Wave already has its own loop function. I haven't played with it very much at all so I don't know how extensive it is, but if Gold Wave could support loop info, then I believe the loop function could be extended to make use of it and that would settle it, especially if it could do the first two things on my useful features list.
Any thoughts about whether this could work in future, whether it be a plug-in or built into Gold Wave? I really hope it can happen!
Thanks for reading.
