DIY Test CDs, can you help me with some ideas?

[cordura21]

So far I thought of the following, please feel free to add to them (for example I want to add something for reverb measuring but I'm not sure of what to do):

Common Tests:

Pink Noise
White Noise
Sine Sweep
Sine waves @ different Frequencies?
=============================
Calibration Tones:

Calibrating 1 kHz Sine tone @ -14 dBFS
Calibrating 1 kHz Sine tone @ -16 dBFS
Calibrating 1 kHz Sine tone @ -18 dBFS
Calibrating 1 kHz Sine tone @ -20 dBFS
=============================
Speaker Tests:

Left Sine Tone
Right Sine Tone
Out of Phase L-R tone
=============================
Tuning Tones:

Guitar Tuning Tones
Bass Tuning Tones
=============================
Other:

120 bpm click (maybe @other BPMs?)
a freeware Dither noise
=============================
Recommendations:

(some recomm. For test tracks in diff. Styles)


Cheers, Andrés

have a couple of tone test tracks that run sine tones from VERY low to VERY high. 20hz to 20khz should do. have the first set be even, have the second section be based on perceptual hearing (what was the name of those perceptual tonal-differentiated loudness curves that are cited regularly?).

if you're going to have guitar/bass tuning tones, it couldn't hurt to have some common tuning tones for mandolin/violin/cello/etc.

along with your left and right tones, have in-between panned tones-pick at least 5 spots in between HARD left and HARD right. this helps you test your soundfield staging, which is dependent not only on the quality of your equipment, but speaker placement.
