Back in the last century, when everybody used phonographs and stereo
speakers, I was able to test and calibrate my equipment with a record that
played sweep tones across many small areas of the audio spectrum, and let me
compare it to a mid-range reference frequency. I used a stereo graphic
equalizer to keep response relatively flat for most of my music. . .tweaking
when in the mood.

In today's world of Dolby 7.1 DVDs and CDs is there a similar DVD or CD
known to anyone in this group that would let me calibrate my system in a
similar way?

What's available in multi-channel equalizers?

Thanks,
Ed

DVE and AVIA are the popular ones. I prefer the Chesky DVD-A for
audio. I guess there are many others.

Few for consumers as they are now being built into AVRs. Mostly not
needed with a decent setup except to fix unbalanced recordings.

It would be cheaper and better to simply purchase a generator. I tend
to recommend the HP 200 series which are cheap and will last several
lifetimes, but more modern instruments are available. Arbitrary wave
generators that can act as audio and RF generators up through 10 to 20
MHz as well as sweep generators are becoming available at reasonable
prices. One HP model even has a "cardio" function which when routed
into a small bass amp will make your puppies sleep all night if it is
played near their bed box.

There are freeware apps abound that will output aiff or wav files for
you to burn. Sometimes in higher resolutions as well, if thats your
sorta thing.
