Hi, Thought I'd air this one to see if there's anyone already using this kind of thing out there. I'd become frustrated by lack of support for musicians in Linux window manager file managers. No default waveform/spectrogram support. No MIDI notation previews. No BPM or key info, etc, etc. I set up Caja to thumbnail WAV files using Sox ... see some screenshots on this forum thread ... http://linuxmusicians.com/viewtopic.php?f=4&t=12514&p=55280#p55280 I'm looking at some other thumbnailers as listed on the thread. I'm thinking of doing some development of the MATE Caja file browser to allow better presentation of audio file waveform thumbnails as currently they can only be square. Maybe LAU members already know of someone who has done this ? No point in reinventing the wheel ... otherwise I'll take this to LAD. ... and now to the BIG IDEA ! For long samples and tracks having a thumbnail becomes more problematic ... it may just end up as a thin line, or something that fits the small thumbnail but is summing the entire track which is probably not very informative. One thing I realised is that I've been using visual recognition of tracks for years. I can pick tracks off my vinyl records based on the look of the grooves ... basically a vinyl representation of the audio waveform. One way of taking this into digital land would be to create a full length waveform, and then process it into a tightly packed spiral and thumbnail it. That might provide better recognition. So that's something I'm working on using Graphics Magick or some other way of processing it. DJ Barney -- ~~~ http://djbarney.org
