Audioqualität Vinyl

Wovon hängt die

Audioqualität einer Schallplatte

ab?

Natürlich von guten dynamischen Aufnahmen und einer guten DMM-Überspielung (Kupfer)

Es gelten hier andere Gesetzte und physikalische Grenzen als bei der CD, die teilweise nur auf LAUTHEIT ausgerichtet ist. Tipps Anlieferung Vinylmaster beachten!

Maximale Spielzeiten beachten!

Ansonsten gilt bei der Herstellung:

• optimal ist schwarzes (graphit) extra schweres Vinyl (tiefe Rillen)
• je mehr Spielzeit um so schlechter die mögliche Qualität
• je schneller die Umdrehungen (Upm/rpm) um so besser die mögliche Qualität
• Außen klingt die Platte besser als Innen, bitte bei der Reihenfolge der Tracks beachten
• Farbiges Vinyl ist schlechter
• Picture Vinyl ist noch schlechter, aber sieht besser aus
• je mehr Bässe das Audiomaterial enthält desto größer ist der Rillenabstand und geringer die Aufnahmedauer bzw. die Qualität
• je lauter die Schallplatte überspielt wird, desto mehr Rillenabstand ist notwendig und entsprechend kürzer ist die Aufnahmedauer bzw. die Qualität
• Extreme Stereosignale benötigen größerem Rillenabstand.
• Das Audiomaterial sollte Monokompatibel sein (nicht nur, damit es auch auf dem Küchenradio gut klingt!) ACHTUNG: Unterhalb von 350 Hz muss das Audiomaterial phasengleich sein!

 

How to prepare a suitable master

To get the best results with your records, you need to read the following points before preparing your master source. Following these instructions will ensure that you are satisfied with the final product:

*

Try not to exceed the maximum recommended playing lengths per side, as longer playing times will lead to a dramatic decrease in recording level and dynamics. On the other hand, the requirements of extremely high recording levels decrease the possible playing time (see the table in the next section for recommended playing times for all formats)

*

Try to place demanding, powerful and exposed tracks at the beginning of the required side and not towards the end of the record. The conditions for recording and subsequent reading of vinyl records get worse with the decreasing diameter towards the middle of the record (the label). The worst possible format with regards to quality is a 7" record at 33rpm

*

Try to avoid using psycho acoustic processors to an excessive degree.

*

If possible, please check the master by using a correlation measurer (it must not be drastically in the red field or have negative values) and a frequency spectrum analyser to ensure the signal does not contain unreasonably large elements in the low frequency range (around 20Hz) and also the top end of the frequency zone (around 20KHz).

*

The lowest frequencies of the acoustic zone that are below 300Hz have to be in phase.

Filter away all sub acoustic signals below 20Hz to avoid possible problems during recording and reproduction.

*

If your recording substantially differs from natural sounds, which is caused by spreading out the energy in the acoustic zone, there is a risk of audible changes to the sound during the transcription. This is due to the limitations of mechanical recording processes and can for example be caused by singing adjusted by processors or electronically generated effects.

*

We transcribe at 2 possible levels. The first is called STANDARD which is a good quality transcription using standard measurements and levels, and the second is called LOUD which is cut using a higher level of transcription without causing distortion on good quality reading systems.

Remember that good reproduction results on the user's side depend on the quality, technical conditions and correct adjustment of the reproduction facilities! **)

**) The quality of the reading system, the shape, the level of the attrition, the cleanness of the needle and the adjustment of the vertical force and anti-skating

*

Try to avoid 7" vinyl formats at 33 1/3 rpm as the possibilities of the recording and reproduction are most limited at this format. If there is no other solution you have to take into account that the final product will be in some way compromised *)

*) Low groove speed limits the recording level and causes a higher decrease of the high frequencies into the middle of the record and can also cause higher distortion levels.

*

If you require additional adjustments or mastering (changes in track order, disregarding some tracks, compilation....) please specify your request exactly on the order form, and note what is on the master and what needs to be done for the final product. - EXTRA COSTS
