[Sursound] Renting a Soundfield Microphone in Germany

2013-05-28 Thread Moritz Fehr
Dear Group,

I am looking for a Soundfield ST350 or ST450 to rent in Germany for a project. 
So far, I have only found a place that has a ST250. Do you have any suggestions 
on finding one of these ?
Thank you very much,

Moritz

As Dave implicitly states, the frequency response of analog tape is 
limited by the playback gap length.  However, while the peak of this 
response is usually around 15kHz, the first zero output is only an 
octave higher and thus the slope has to be quite steep.  (I have no 
access to graphs at present.)  But it does sound good!

Apparently the reason that above 48 khz is frowned on by some is nothing to
do with niquist/the range of human hearing etc but rather distortions in
reproduction equipment when using very high sample rates that can introduce
artifacts and actually make things sound worse. This article makes this
point and evewn includes some experiments and filesw you can use to test on
your own eqwuipment to see if these artifacts are produced on your system :

As for bit rate - well most people agree, especially in the mixing stages,
a higher bit rate is a good thing.
