I gather you do the file upload frequently. Hence, it may be worth the trouble to put up a chain command. Once you have succesfully created a file with the correct volume you can use the values as prototype. If your sound files are very different in style and genre, it may be better to use another m...

A portable seismograph may better suit your needs. At least if the phenomenon is vibration-based. There is sure a way to make those pulses visible. You could for example observe how a detached laser beam (laser pointer hanging from the roof) - reflected by a looking glass on the shared wall - moves....

I do not quite understand what do you want to achieve. You write that the game is from an aerial view, isn't it? If so, it all depends on how high the view is. The higher the position, the more high frequencies are attenuated (air absorbtion) and so are the echoes (maybe even more, since the high fr...

There's alternatively my plug-in kicking about that is intended for such tasks:

Or perhaps, if there was some arbitrary, hard limit, or Preference, for the amount of lookahead and lookbehind, it would be an acceptable compromise. Any reason to not just make the selection a bit bigger? I see Paul's point. Imagine you pick a vocal part within a single tune. You want to add a rev...

I've been looking for a way to get rid of the crackles that remain in the silent parts of the sound. I've tried click-removal, but it seems to fail completely, even with extreme values. It now came to my mind that I've already written a plug-in for extreme click sounds. I've modified it to work with...

Sorry, the code was indeed for mono sounds, And there's a wrong step-size, thats why it speeds up. Here's the correct version: (defun noise-red (s) (snd-avg s 50 1 op-average)) (multichan-expand 'noise-red s) As you can see, the value is much higher than before. You can choose a smaller value and si...

A smart DSP-trick to reduce noise in the upper regions (while keeping a proportional big amount of the useful signal) is to average the samples. (snd-avg s 7 7 op-average) Put the code into the nyquist prompt and press OK. The value 7 is the amount of samples that are averaged. Higher values result ...

I didn't have any special equalizer in mind. In any case, it would have make sense but in connection with a computer and it seems that you have a combi device. Let us know how you get along with Steve's plug-in. By the way, are the results from your spectrum analyzer comparable with the spectrum vie...

I've assembled a sound example that shows what the signal is like after the auto-corellation. It also shows the difficulties that have to be overcome when extracting the correct label positions. I've only taken the averaged peaks (resulting in a sample rate of 4410 Hz) in order to speed up the proce...
