My next thought involves an already inexpensive Polk center available
even cheaper at Fry's. I think I have a pink noise source on a
Stereophile test cd.
The Delos "Surround Spectacular" test disc (I believe it is
still available from the Delos Records web site) has Dolby
Surround (matrixed) encoded pink-noise test signals that
include left, center (left plus right), right, and surround
(left minus right) signals that make it pretty easy to
compare spectral balance in all four Dolby Surround
channels. The Ovation Software "Avia" test DVD has similar
signals in Dolby Digital form for the standard five
channels. (They also have a web site that takes orders.) The
version put together for Sound & Vision magazine even has an
additional test signal for the center-back channel in 6.1
systems.
All three also have test signals to help set up subwoofer
levels and crossover phase dovetails. The Delos disc even
has signals to check out the ability of a Dolby Surround
(matrix) decoder and three speakers up front to deliver
half-left and half-right imaging with three front channels
and a derived (left plus right) center feed.
Thanks. When that center channel happens, I'll check out the Delos test
disc.
Isn't the levels signal out of most receivers pink noise?
Both my receiver and DVD player (as it has builtin decoders) has level test
signals that sounds like pink noise to me.
