On getting a good studio master finished product quality take with a Shure SM58, SM57,...

Since Michael Jackson used an SM7 and possibly Whitney Houston while recording in the studio and by viewing the schematic on coutant.org we can see there is a low cut incuctor of 240mH inside the mic for creating the proximity compensating low cut filter... And since the SM57, SM58 seem to have the same capsule as the SM7... And since the inductor is connected in parallel to the output of the mic... Then why not creating an inductor and placing it inside an XLR female to male barrel adaptor so that we approach with many microphone what the legendes used... This is the idea behind the Pleiades inline filter created a few years ago and published on euroelectron. Also Michael Jackson sung with many cylindrical sound absorbers around him, possibly to extinguish early reflectrions. Fairly rescent Pleiades experiments are done using the fabulous acoustics of outdoors... Anyway, after meeting Liliya and then seing her performing live on youtube with her band possibly holding an SM58 it was decided to create a passive filter for an SM58, SM58, Unidyne III etc with an inductor of close to 200mH which surprisignly had not been made yet although most other values of inductance have alreay been used on Pleiades filters.

A simple microphone experiment for better vocal sound

At your risk. Needed a microphone, a recording device, could be even a mobile phone, A usual place like a living room, a extra quiet outdoors recording place. One take is recorded holding the mic above head about 12 inch from nose indoors. Then the same outdoors. You can be amazed by the difference outdoors makes. It sounds close, intimate, no s problems, no bluriness, focused, inteligible, less bass heaviness crystal clear, and the singer sounds much younger., It sounds profesional. One reason may be... no close reflections which come back to the mic very quickly since they are from close objects. It is usuful to remeber that the mic has no brain to forget capturing early reflections. See also the Motion Picture Engineering book refered to on older euroelectron posts. If a good mic is used compensated for flat frequency response from producer's brain to listener's brain such as passive inductor Pleiades microphone inline filters, to result can be amazing.

Hit Songs may need a few electrical signal transformers ( 2 coils of wire hugging each other) in the analog signal path.

Some microphones even have one inside them, for example Shure SM57, SM58, RCA 77DX, Perhaps AKG D25 etc. Why do they create a magical sound? They recreate the music signal as the first wire is not connected to the other, music energy is transfered by an electromagnetic energy wave. They may introduce a subtle high frequency rise, see Rupert Neve interviews on youtube...

Just 2 SM58 coincident pair at right angle to each other can cover a PA concert

It was tried at Castaniani village of magestic view in the north part of Hellas, full of maintains and super clean air. Shure SM58 has no bass boost proximity effect (ie frequency respone is getting flat) at say a distance greater than 1 meter. So mics were placed in front of conductor, singers were placed about 1 meter away in center, behind them there were acoustic or amplified instruments, behind them a choir. Each PA speaker was placed behind each mic, so that feedback would be minimum. The venue was outdoors on a magnifiscent August night. The Yamaha if memory is correct mixing desk was only used as an amplifier with perhaps a bit of reverb. Roadies were very releved that they had so little to carry. Everybody was happy after the concert and congratulations were given...

Did you know A.D. Blumlein...

electronic engineer, one of the best in the history of mankind, inventor of the modern stereo disc cutting method of 2 deegrees of freedom at 90 degrees to each other for each left, right channel while cutting the groove with music, inventor of the coincident mic pair technique with each directional mic at 90 degrees to the other... On the first date with his to be wife, he took her on a trip to the sky, flying with her an aeroplane...

Microphone comparison: Sennheiser MD421-II, Neumann TLM 103, Electro-Voice RE20 with or without Pleiades gentle slope high pass filter (130 ohms, 20mH)

Only the RE20 was tested with or without Pleiades filter and its internal low cut was on at both cases. The test was done on 24011817 date time code at SNFCC studios. 2 women and 2 men of young age, active in the audio engineering were the listeners. The test was quasi blind in the sense that Lefteris was playing the different files, so he knew, Fotini, Fey might had been influenced by him as he was the first to vote everytime, and i may be biased as i could more or less guess which mic with filter was which, but the rest 3 of us did not know which mic file had been playing through the Genelec coaxial monitors. Kelly who had booked the session did not turn up being ill so it was decided to record Fey singing Hurt - Cristina Anguilera using the original backing track from the CD single. The recording room is small but treaed acousticaly. Mic was in front of singer at bout say 8-9 inch. i would have possibly prefared 12 inch for less proximity effect and from 45 degrees above singer's head. but we did not do much mic placement tests. An objective of this test was whether we could make a vocal sound as good as Christina's. And whether the Pleiades filter would make the sound close to that without further EQ. 1st mic is MD421 with its low cut almost full, (I guess it would have sounded better with full low cut). While we were testing before recording (mabe greater mic distance) i was impressed with the clear sound of this microphone. Score out 0f 10, Le:6, Fo:6, Fe:4, Ge:5 (George). Total:21 2nd mic EV RE20 with Pleiades in line filter. Le:7, Fo:8, Fe:7, Ge:5, total:27 3rd mic Neumann TLM 103. Le:9, Fo:9, Fe:8, Ge:3, total:29 4th mic EV RE20 with its low cut only, Le:7, Fo:5, Fe:6, Ge:3, total:21 i gave on 2 cases 3/10 as i was hearing bass heavines compared to Christina's original backing track + vocal that we were comparing. Lefteris commented that he was imagining how the TLM will sound after eqing it. We were happy that on the higher rated cases we could approach the quality of recording of Christina. Fey did a great singing job. Many thanks to all participants and SNFCC. The files may have been deleted.
