Hi, this looks nice, but do you think it would pay off to put less bulky formats online? Only the videos for Puckette take around 3Gb, I think (don't remember anymore). Is the high quality really necessary? I finally made arrangements to edit and post most of the interviews Kevin and I

For instance you could do a very straightforward: ffmpeg2theora *.mov for processing all mov files in a directory. That should reduce the size to about 15 % of the original with a very good quality/size ratio. Kind regards, Lorenzo Frank Barknecht wrote: Hallo, hm, ogg theora would be

Hi, my laptop trio Endphase (http://www.endphase.net/) is going to work out our archived recordings, so that we get decent stereo versions to spread around. Since many of them are multichannel (from 4 to 8) in different setups (not necessarily only 2d around the audience), we'll be searching for

Hi Joao, It sounds like you need a stereo auralization of various multichannel diffusion pieces. One option is to make a binaural down-mix of the multichannel material, although that has the restriction of only sounding good on headphones. This would still leave a decision on where to

[PD] making scales from frequency values

2009-07-20 Thread J bz
Dear all, I have five chimes. I've worked out the frequencies (using Audacity) of the 5 strongest partials of each chime. I now want to be able to work out how to change the octaves of the various partials? My original intention was to find the nearest midinote and just use those but after

Re: [PD] making scales from frequency values

2009-07-20 Thread Andrew Faraday
Hey Jbz I'm not sure if this is what you want, but if you convert a midi note to frequency [mtof] then multiply by integers, you get the natural partials. So if you multiply the outlet of [mtof] by 2 3 4 5 and 6. then you can change the multiplication figure, etc. I think that's the effect

2009-07-20 Thread Derek Holzer
Unlike all the rest of the equal-tempered scale, octaves are easy, just divide by half or multiply by two (or multiples thereof). If it's thirds and fifths and all that, it gets a bit more complicated unless you are into just intonation where the ratios are actually the ratios and haven't been

Dear Mike and Andrew, Thank you for your speedy responses, though I think I am not explaining myself very well. I don't want to use mtof or ftom as these objects even out my ratios. What I'm looking to do is create a scale (say 12 notes for example) out of these ratio's with the possibility of

I'll be honest, this sounds a bit advanced. It's logarithmic and thus beyond me. However... Perhaps try to find a list of just temperament or world music scales and their frequencies. See if any match up to the scale you're trying to achieve. Andrew Date: Tue, 21 Jul 2009 00:52:24 +0200 From:

Hi Andrew, it's really not so complicated, it's just simple math. If the root and partial frequencies of his chimes don't fit any note in an existing scale, then trying to squeeze them into one won't sound good. It's also a lot of list-searching and ear-guessing to see what the closest fit

Just FYI, looking at BT2,BT3 and BT4 I see that the ratios of the first partials is pretty close to a major second. Also, the ratio of the first and second partials is just about 2.64 for each of the tones you have given, which works out to something like 1 octave + a 4th (between the major and

How do these objects even out your ratios (or, I guess, what do you mean by that)? Finding the difference between two frequencies after converting them to a MIDI value allows you to work linearly instead of logarithmically, which is just easier--well, for me anyway. For example, after
