Hi,

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?

Hi,

I have several tone  files saved.  Some only differ in subtle details so it isn't always obvious which tone set is running.  Is there a way to have the tone file name displayed?

Hi,

I have a similar problem.  I want to demonstrate Fourier Synthesis.  That is easy for a square wave but triangle and sawtooth waves need a phase reversal on odd tones.

The obvious way to specify the phase reversals is to give the tones concerned a negative frequency.

An even better solution would allow the relative phase of the tone to be specified.

So why no negative frequencies?
