findjammer - Thanks for asking. I've been fiddling around with my LoopLibrarian project for about 5 years and I use it constantly. Others have suggested that I turn it into a product I can sell and I spent a lot of time this year preparing for that.
It resembles a Windows Explorer View, but it provides full control over the data in the file view, such as sample rate, bit depth, duration, BPM, pitch, etc, and can sort by any of those columns. It performs bit depth conversions with dither, sample rate conversions, and manages ACID properties (I managed to reverse-engineer the ACID chunk). It supports and converts WAV, MP3, OGG, AIF, FLAC, WMA, etc. It also shows MIDI details for each channel, and manages MP3 and manages metadata on audio files.
I just finished support for drag and drop to and from the program (had to learn to use COM objects), and a new on-screen keyboard that helps with setting the pitch when acidizing files. It outputs MIDI to any device, or uses soundfonts. I'm still working on some ASIO issues.
So it tries to do a lot, but it becomes a bit disheartening when seeing other products that do much more, and have cool interfaces for so little money. So it will probably continue to be a hobby. Fortunately, I make a living developing other software.
But again, congratulations to you on your samplesort project, and good luck.
