When creating test tones using software like NCH Tone Generator what variable amplitude should they be set to. I noticed that the sine wave test tones on the Bink's audio test tones are described such as...
11 16 -1dB 30s
12 20 -1dB 30s
13 25 -1dB 30s
14 31.5 -1dB 30s
What is the purpose of setting a variable amplitude for each tone recorded?
