Todo List

Global BlackmanHarris62: where did these come from?

Global FindNextMax

export this to sms.h and wrap in pysms

Global GetStartingPeak: should this return something?

Global IFFTwindow: read X. Rodet, Ph. Depalle, "Spectral Envelopes and Inverse FFT Synthesis." Proc. 93rd AES Convention, October 1992

Global rdft: (optimize) replace math.h trig functions (table lookup?)

Global ReAnalyzeFrame

explain when this is necessary

is the return value info correct? Why isn't it used in sms_analyze?

mae this a < 0 check, but first make sure sms_fundDeviation does not return values below zero

Global SMS_ANAL_DELAY: this should be a parameter in AnalParams

Class SMS_AnalParams

make it variable) that are accumulated for good harmonic detection and partial tracking. For instance, once the fundamental frequency of a harmonic signal is located (after a few frames), the harmonic analysis and peak detection/continuation process can be re-computed with more accuracy.

Global sms_analyze

sort out return meanings

when deviation is really off, this function returns -1, yet it isn't used.. is it being recomputed ??

Global SMS_DBG: write details about debug files

Global SMS_DBG_DET: make this show main information to look at for discovering the correct deterministic parameters

Global sms_dCepstrum

add anchor point add at frequency = 0 with the same magnitude as the first peak in pMag. This does not change the size of the cepstrum, only helps to smoothen it at the very beginning.

Global sms_dCepstrumEnvelope: does this have to be a pow2

Global sms_fft

if sizeFft != power of 2, there is a silent crash.. cuidado!

Global sms_filterHighPass

this filter only works on sample rates up to 48k?

Global sms_freeSynth: is there a way to make sure the plan has been made already? as it is, it crashes if this is called without one

Global sms_getWindow

note on window scales

Global sms_harmDetection

is it possible to use pSpectralPeaks instead of SMS_AnalFrame?

move pCHarmonic array to SMS_AnalFrame structure

this will allow for analysis of effectiveness from outside this file This really should only be for sms_analyzeFrame

Global sms_initFrame: make this return void

Global sms_initModifyParams

call this from sms_initSynth()? some other mod params are updated there

Global sms_interpolateFrames: how to interpolate residual phase spectrum

Global sms_residual: why is residual energy percentage computed this way? should be optional and in a seperate function

Global sms_residualOLD: why is residual energy percentage computed this way? should be optional and in a seperate function

Global sms_scalarTempered: remove this define now that there is sms_scalerTempered

Global sms_spectrum: remove this return

Global sms_stochastic

needs to be pre-windowed to match the windowing effect of the deterministic, so when they are summed then they can be ifft'ed and overlap-added properly

why is it also multiplied by 2? Why aren't the coeffecients just stored with gain already multiplied?

Global sms_synthesize: use a comb filter of harmonics to better combine the signal here

Global sms_windowCentered

do I need to garuntee that sizeWindow is odd-lengthed?

Global StocSynthApprox: cleanup returns and various constant multipliers. check that approximation is ok

Global ZeroPoleFilter

will forgetting to reset pD to zero at the beginning of a new analysis (when there are multiple analyses within the life of one program) cause problems?
