here is the link or the discussion at Snake Oil Audio it starts at minute 2. If you dont understand German use the subtitles

Moin Michael, mal wieder eine schöne "Perlenpräsentation", Platten die so manche Krautsammlung vervollständigen würden. Da muss viel zusammenkommen, dass man die mal findet, ohne Vernetzung, nahezu unmöglich. Trotzdem immer schön, die Platten mal wieder zu sehen. Gruß Patrick

Michael this topic of the amplified pops and clicks is really interesting for me. I was fitted with hi-tech digital hearing aids about 6 weeks ago and I get exactly the same effect when listening to my top of the range Linn turntable and Naim amps. The clicks on my records sound twenty times more accentuated through my hearing aids than just listening to the speakers!! It must be to do with compression even though I have dedicated music setting on my aids with all of the digital processing turned off. I wonder if this is very similar to your direct connection from the camera to your pre-amp and You Tube processing ? Keep up the good work I love your channel. Best wishes Michael (UK).

Hi Michael, in my opinion the heavy compression is due to the camera's audio settings. Perhaps it is possible to disable or at least minimize audio-compression on your camera. YouTube does it's share but what I heard on your video was way more excessive that the usual YouTube compression.
Never the less I really enjoyed your video and listening to music with like minded music lovers. Best wishes from Vienna 👍

Hi Michael miss you on Rachel’s channel, can you do an updated video on your record collection and Listening room. Cheers from Australia

Michael, The noise or distortion you hear when connecting the phono preamp directly to your video camera is due to the imbalance between the audio output level at the phono preamp and the maximum audio level at the camera input. The signal is probably saturating the camera's audio input, and this saturated signal at the input of the analog/digital converter is creating these audio glitches. To prove this, simply connect the audio output of the line preamp to the camera instead of connecting the phono preamp. Reduce the signal level and you will probably see a decrease in noise.

Es kann sein das die Kamera den Ton bearbeiten tut. Also eine Dynamik Einschränkung statt findet. Audio Einstellungen anschauen.

Hey have you had a chance to listen to one of my favorite bands from New Zealand

Hallo, Michael. Gutes Video, aber eine FRAGE: Vorstufe direkt via Kabel an die Kamera angeschlossen, so dass Kamera ein ANALOGES signal bekommt. Hat die Kamera einen analogen AUX-Eingang und integriert einen Analog-Digitalwandler? Würde mich wundern. Es sei denn, die Kamera würde analog arbeiten, was es ja nicht mehr gibt.

I would suggest using a stereo mic in the X/Y configuration positioned where you normally listen

Hallo Michael,
das Problem was du im Livestream schilderst ist mir auch aufgefallen. Allerdings hat dies nichts mit der Kompression der Audiodatei zu tun, wie Thorsten meinte. Es ist ein Audiokompressor der in deiner Kamera greift, das ist sowas ähnliches wie eine automatische Lautstärkeregelung für die Aufnahmelautstärke. Daher werden leise Passagen sehr stark verstärkt (eben auch die clicks und pops). Schau mal im Menu der Kamera ob du das irgendwo ausschalten kannst. So eine funktion ist nützlich wenn man ein Mikrofon benutzt, allerdings für Musiksignal eignet sich diese Funktion nicht

Seems quite obvious that the elephant in the room, the weakest link in the whole signal path is not the Youtube compression, but the analogue to digital conversion inside the digital camera? Maybe compare the quality / cost of such circuit & chip to rest of the equipment used. Perhaps it’s cheaper by a factor of 100-1000x vs turntable, phono stage, and preamp. If one would use an analogue to digital converter that matches the analogue chain, the signal uploaded to Youtube would be reproduced very close to the actual analogue input
