This must had been recorded at Columbia Studios EMI in Athens.

There seem to be varispeed between the video shorts. 

So they are also didactic to hear the difference that a change in tape recorder speed does to the vocal timbre.

This is at slower, perhaps original speed, and without reverb. The original reverb, perhaps this too must have been either the EMT plate, or the Columbia Studios Echo Chamber with Leak power amplifier with electronic valves (electron tubes).

Higher speed plus reverberation. The original reverb, perhaps this too must have been either the EMT plate, or the Columbia Studios Echo Chamber with Leak power amplifier with electronic valves (electron tubes).

Music is the language of the heart and mind

Mack the Knife - Luis Armstrong live at the BBC

 

Some songs I like and my explanation of Hit Song Elements will be soon added on previous post "A Letter to Clive Davis"

The very nice Shure Unidyne B, 515SD, 515SB microphone

 At your risk.

This microphone sounds very nice connected directly to the preamplifier! The bass sounds correct as this microphone is engineered to start cutting below 200Hz thereby correcting the bass emphasis proximity effect.

Signal Path:

male voice singing When I Fall in Love - Nat King Cole (same key) - Shure 515SD  made in Mexico at 24in, 30 degrees above head -  Sony TC-D5M - TDK SAX - Sony TC-D5M (reproducing) - Pleiades 2N3053 power amplifier - Celestion Ditton 150 - small room with some panel bass absorbers

Same experiment was repeated outdoors at a noisy environment. Impressive results, voice sounds closer to reproduction speaker/ High frequency definition increases.

This is possibly the first microphone I have bought. And one of the 1st I had is the original Shure 515SB made in U.S.A. which was used for lectures in my family's central branch of Homer schools of English. It sounds amazing.

Foe further tests windshields will be needed.

Shure SM58 directly connected to Altec 9014-A passive EQ

At your risk.

Signal Path:

male voice singing When I Fall in Love - Nat King Cole (same key) - Shure SM58 made in Mexico at 24in, 30 degrees above head - Altec 9014-A EQ - Sony TC-D5M - TDK SAX - Sony TC-D5M (reproducing) - Pleiades 2N3053 power amplifier - Celestion Ditton 150 - small room with some panel bass absorbers

Very promising results were obtained by cutting 7dB at 250Hz and 315Hz. All other controls at 0 dB (no reduction).

A simple vocal recording filter for SM58

At your risk.

It happened almost by chance.

An inductor of 100mH was connected in series with a capacitor of 100nF. So both in series between SM58 and preamplifier recorder Sony TC-D5M.

Signal path: male voice singing When I Fall in Love - Nat King Cole in the same key as Nat - Shure SM58 at 24in, 30 degrees above head - 100mH in series with 100nF - Sony TC-D5M - TDK SAX cassette - TC-D5M (reproducing) - Pleiades 2N3053 power amplifier - Celestion Ditton 150 

It sounded very nice with no bass emphasis, the capacitor corrects bass emphasis by low cut. The inductor may possibly remove some mid emphasis? and does not seem to cut high frequency content. This is possibly because the core may be a mu-metal one spare from a Coles 4038 internal mic transformer. As frequency increases the permeability decreases. So inductive reactance may not be proportional to frequency.

Other combination that worked fine is 100mH in parallel with 220nF and total in series between microphone and recorder.
