Amplitude setting

Recommended Posts


I would like to be able to set the tone amplitudes as a voltage level rather than in dBs.  Why? 'Cos Fourier Synthesis of simple waveforms uses integer divisors for the amplitude.  Converting to dBs is a minor pain.  Worse, the conversion loses precision.  Decimal points on the dB amplitude would help but it seems simpler to allow amplitudes to be specified in volts - with a suitable precision.  After all, the dBs will be converted to a floating-point level, internally, so why not allow that as an input?
