Can't you do test tones with zeta 2 and a sign impulse?
Yes, but synthesizers can't be counted on to produce a pure sine, or truly random white noise, and it's difficult to create specific peak or RMS values or specific frequencies. I do occasionally use Meldaproduction's free tone generators MNoiseGenerator and MOscillator for the convenience of a plugin, but prefer to import files I've created and saved with Adobe Audition.
Audition lets you generate a wide variety of test tones (sine, square, triangle or sawtooth) of specific amplitude, including swept sines that start and end at specific frequencies, mono or stereo, integer or floating point, pure or with harmonics. They can optionally be modulated in frequency, amplitude or phase.
