I've been thwarted twice cos the machines I can afford off eBay died after labouriously loading da humungous modern compilers. I've tried to move my software to a modern compiler but 2 decades is a long time to be away in software. Redmond will stop support for XP next year so I'm stuck. I'm presently using XP to run VirtualPC to run W98 to run DOS for my own software.
I can now make better measurements in my shed than I could using anechoic etc in the 90s using my DOS version of Angelo's method.Īlas, my software requires Windoz98 and the machines that do this are now dying. When I emerged from the bush after more than a decade, I found computing power in the cheapest laptop was more than sufficient and good A/Ds could be got cheaply though you have to be careful what you use. I developed the theory for this in the early 80's for production testing of speakers for response & THD in the theoretically shortest possible time but the computing power and particularly good A/Ds were too expensive for what we wanted. The cheapest way to get a B&K reference mike is to buy a 4133 or 4191 capsule off eBay (making sure it is undamaged and still has its calibration curve) and make your own 200V preamp (what the capsule screws into) Les Watts at MicBuilders can advise as he's done exactly this.įrom reading the Fuzzmeasure blurb, they are using Prof Angelo Farina's exponential sweep method. The reason for B&K is I believe their calibration curves D You need to use the reference measurement to calibrate out the source AND apply the measurement mikes calibration too. I could not pick one over another so decided to give them away.Ĭlick to expand.I'm not a rich Mac user so have no idea of how good Fuzzmeasure is. >I wonder if it would tear the fabric of space and time if you recorded with one of those mics and then applied the same IR to it.įinally, my motivation to make these available was because several parties asked for them and even offered to pay. Whatever sounds good to you! You can call it modelling of vintage mics if you want, but I thing it is just another way to process your sounds and have fun, just like other IR reverbs.
>I'm curious what the best application would be for this.
I have not found a satisfactory fig-8 measurement mic, and I doubt that one can exist. It is far from a perfect system, and for me the biggest problem is comparing a figure-8 ribbon which doesn't see the sides, with an omni measurement mic, which does. we don't always know exactly where the capsule / ribbon sits within the mics. I have a ridge of foam either side that I line the mic up with. It has been suggested that I should do this outside, but those who have visited Yorkshire will know why we don't. So we see some proximity effect, especially with the ribbon mics. >What distance do you measure at? 1m is good but you need some space for that.Īround 30cm. I should probably invest in a B&K, but they are a lot of money! I use a Beyer measurement mic, which is probably mid-way between the B&K and the Behringer. But I will try to dig out the calibration sweep(s) in case you want to play further with the processing. >could you also upload an impulse response of your Source speakerĪs I understand it, Fuzzmeasure automatically corrects for the calibration mic.
