• 01:4001:40, 18 January 2012 diff hist +6‎ Additive synthesis ‎ →‎Discrete-time equations: That's a little better form.
• 01:3701:37, 18 January 2012 diff hist −1‎ Additive synthesis ‎ →‎Discrete-time equations: Missed another thing.

• 01:2501:25, 18 January 2012 diff hist −3,727‎ Additive synthesis ‎ →‎Discrete-time equations: I replaced the Harmonic form and Inharmonic form with General form. Mighta cut too much.

• 20:5420:54, 17 January 2012 diff hist +97‎ Additive synthesis ‎ →‎Time-dependent amplitudes: Actually it should be f0, Olli. You don't want any of the spectrum of the kth harmonic spilling into the (k-1)th harmonic or (k+1)th harmonic.

• 02:5802:58, 17 January 2012 diff hist +12‎ Additive synthesis ‎ →‎Inharmonic form: It's cos(θ(t)) = cos(ωt+φ) = cos(2πft+φ). θ is whatever angle that you're taking the sine or cosine of. φ is the phase offset. Think of a bunch of vectors spinning around at the same rate. φ is the offset, the phase.

• 23:3923:39, 16 January 2012 diff hist +1,546‎ Additive synthesis ‎ →‎Definitions: A little more rigorous. Not saying that this is done.
• 22:5322:53, 16 January 2012 diff hist +301‎ Additive synthesis ‎ →‎Definitions: A little exposition regarding Fourier series and audibility that leads to the finite number of terms in additive synthesis.

• 21:0621:06, 15 January 2012 diff hist −69‎ Additive synthesis ‎ →‎Theory: Let's ditch the DC term baloney here. Perhaps earlier in the Theory section with continuous-time where we relate this to Fourier series is the place to have DC and an upper limit of infinity.

• 19:0719:07, 15 January 2012 diff hist +1,485‎ Talk:Additive synthesis ‎ →‎Theory section needs a drawing like in the JOS article.: new section
• 18:5418:54, 15 January 2012 diff hist −119‎ Additive synthesis ‎ →‎Theory: Removed reference to supplemental note.
• 18:5118:51, 15 January 2012 diff hist −3,363‎ Additive synthesis ‎ →‎Footnotes: Removed poorly and inconsistently formated section that only demonstrates non-understanding. Clusternote, I know you're dying to be vindicated and contribute *something*, but this doesn't help anything. Tag: section blanking
• 18:4818:48, 15 January 2012 diff hist +423‎ Additive synthesis ‎ →‎Theory: Missed one Θ. Added a little explanation for what, fundamentally, the frequency of each partial, be it harmonic or not.
• 18:4218:42, 15 January 2012 diff hist −29‎ Additive synthesis ‎ →‎Theory: Changed sin() to cos(), Θ to φ for consistency to the rest of the article. This section is the right idea and there is more we can do to make this slip seamlessly to the discrete-time representation.

• 21:5221:52, 14 January 2012 diff hist +1,548‎ Talk:Additive synthesis ‎ →‎Inline {{TeX}} vs HTML and what truly tidies up.: We need a simple graphic. Invitation to Clusternote to create and upload it.
• 20:4420:44, 14 January 2012 diff hist +143‎ Additive synthesis ‎ →‎Theory: Added one more fact that might help Clusternote understand instantaneous frequency in a discrete-time context.
• 20:3420:34, 14 January 2012 diff hist +121‎ Additive synthesis ‎ →‎Inharmonic partials: Changed \phi to \theta and "phase" to "angle". They be slightly different, conceptually.
• 20:2220:22, 14 January 2012 diff hist +92‎ Additive synthesis ‎ →‎Harmonic partials: Added atan2( ) function to the phi_k[n] definition, similarly to r_k[n].
• 20:1220:12, 14 January 2012 diff hist +106‎ Additive synthesis ‎ →‎Theory: Inserted some \, to force LaTeX rendering of all <math> expressions. I am not saying that this is the best way to do it, but it's consistent. I still think it should be reverted back to where it's in-line HTML, but I don't know.
