Thanks for the update. Hasn't been long since I last downloaded this and it keeps rolling on. Given a focus is on sound editing I do wonder about something. In the 90's sample editing was tedious when you needed to zoom in and find that sweet spot for marking, usually sound or silence. What I wonder is if you have any plans to alleviate this? Such as with a transient or sound detector? I've become used to the convenience of software that allows moving from transient to another. And it would be useful in an editor.

Thanks for trying out the program! I don't have any peak/transient detector code of my own but if there's something in the public domain, I'd love to be pointed to it.

Sorry, I've tried to find this myself but all I find are complicated papers on advanced FFT techniques, when I know it is a lot simpler. The most basic technique would seek zero or seek sound. However if there is noise as would be expected this isn't practical and would be too simplistic. Next to that would be specifying a threshold or amplitude to work in and finding sounds that meet that criteria.

There's some simple code by one Michael Gruhn for finding transients. The only thing I haven't found what basic algorithm he uses or even example code. But I do know of FX code that uses it. So I'll just paste here I think. It's in a language called EEL which is like C. So in the following the @init sets it up. The @slider code specifies user changes from GUI. The @sample code would run for a block of samples. If I've understood it correctly the gain it calculates would detect a transient if over 0. The spl0 and spl1 represent stereo samples at that point in time in float averaging -1 to +1.

The general idea is to run two envelope followers at different speeds. One is slower than the other. Then when the slow one catches up and a difference is found that represents a transient.

slider1:0Attack (%)
slider2:0Sustain (%)

@init
b1Env1 = -exp(-10 / srate );
a0Env1 = 1.0 + b1Env1;
b1Env2 = -exp(-62 / srate );
a0Env2 = 1.0 + b1Env2;

@slider
attack=slider1/100;
sustain=slider2/100;

@sample
maxSpls = max(abs(spl0),abs(spl1));
env1 = (tmpEnv1 = a0Env1*maxSpls - b1Env1*tmpEnv1);
env2 = (tmpEnv2 = a0Env2*maxSpls - b1Env2*tmpEnv2);
gain = env2 - env1;
(gain > 0) ? gain = exp( log(1+(env2/env1))*attack ) : gain = exp( log(1+(env1/env2))*sustain ) ;
spl0 *= gain;
spl1 *= gain;
