A bit OT, but listen to the "get voice out of head" clip with headphones.

What the SPL Vitalizer does sounds dangerous:

"Und jetzt aufpassen: Mit Hilfe von komplexen Filterschaltungen vierter Ordnung erzeugt der Vitalizer frequenz-und amplitudenabhängige Verzögerungen (Phasenverschiebungen) bis zu einem Bereich von gut fünf Millisekunden. Das je nach Frequenzbereich und Pegel unterschiedlich stark verzögerte Signal wird dem Originalsignal zugemischt. Dadurch werden u.a. die Impulse der Höhen teilweise verbreitert, zum Teil aber auch die Mitten durch Phasenauslöschungen bedämpft. Das Gehör erhält die lnformationen der verschiedenen Freqeunzbereiche nicht mehr zeitgleich, sondern in Portionen nacheinander, so daß es sie der Reihe nach „verstehen“ kann, Maskierungen, also ein „Übertönen“ bestimmter Frequenzbereiche durch lautere, dominierende Frequenzen wird ausgeschlossen. Dadurch entsteht der Eindruck räumlicher Tiefe und einer schärferen Differenziertheit des Klangbildes."

And any village studio can afford this device.

Sorry, I couldn't find an English explaination.


Sad that the Lexicon reverb examples are only available as Youtube stuff, so I only listened to them only with headphones from my computer, but I believe the Chamber algorithm could be fine for ancient music:
Product: PCM Native Reverb Plug-in Bundle | Lexicon Pro

Sorry, I know all this is getting very very very OT.

I think it's not OT at all. Rooms and loudspeakers ARE one system but to get the big picture one has to include recordings too. This brings up audio's circle of confusion again...

yes very true. unfortunate however that mostly all but a few 'classical music' orchestral recordings have the bass mixed down to mono below about 100hz, as im no fan of orchestral music.

Are they mixed that way intentionally, or is it just a recording artifact?

I know a lot of vinyl is cut that way to make it cut cleaner. But I don't know why it would be like that for modern digital releases.

Bass below 80 Hz does not affect spatial attributes of sound reproduction in acoustically small spaces. See Martens et al., 2004.

with studio recordings at least, Im certain that most studios would not use 2 mics for recording the output from a bass amp, or also in many cases a guitar amp either. stereo guitar is often done with 2 mics and 2 amps simultaneously, or just multitracked and recorded twice. stereo elec bass may also just by DI'ed in alot of cases, provided its of any use to record in stereo, eg if a flanger/phaser is used for EFX and a fuller harmonic structure(or exagerated one) is desired. A 'Dark' bass with little overtones wouldnt really be noticable in stereo unless it is panned left to right, rather than ACTUAL stereo recording.

presumably to reduce stylus clipping at large displacements?

Not a cutter but I'll take a guess. Basically even if it is true that bass transients are somewhat benign (debatable but not getting into it) the truth is that a lot of material will have bass transient and reflection information present on the recording. Bass is the largest wave so it will be the largest groves. When a sound is in phase it will cut horizontally. If a sound is out of phase it will cut vertically. When both are present as in bass transient information it's more of a circular movement that can pop the needle out of the grove.

basically what i figured...except the large(r) groove would be wider and deeper, wouldnt it? since displacement is roughly 45 left 45 right in stereo , and just depth in mono...if i remember right...........
