Subject: RE: [motm] Comparing VCO modules by recording

From: "Adam Schabtach" <lists@...>

My thought, upon seeing that post, is that it didn't make a whole lot of sense because aside from the issues you mentioned, the recordings would most likely be done through different audio interfaces. One VCO could be recorded through a Lavry, another could be recorded through the mic input of some cheap laptop. My MOTM sounds different recorded through my Apogee 800 than it did through my MOTU 828mkII. So yeah, what you said about "in the same studio with all parameters kept as equal as possible."

Subject: [motm] Comparing VCO modules by recording

A recent (unsigned) post asked for WAV files of MOTM VCO outputs,
presumably for comparison with other VCO makes. I would be interested
to know whether anyone thinks that recordings suit this purpose very
well. Problems would surely dog this approach, vs. actually having the
modules side-by-side in the same system and doing A-B listening tests.

The files being compared could have been produced with different
sampling rates. The recording levels most likely would have been
different. The psycho-acoustic effects of simply playing back the
∗same∗ recording at different levels of amplification can be
significant. If it is indeed reasonable to make comparisons this way,
it seems to me that the recordings being compared would all have to have
been made in the same studio with all parameters kept as equal as
possible (as when Paul S. posts samples of different sounds for
comparison). Thoughts?

Thanks,
