Re: Analyse Frequency Changes and Increase Sampling Rate

Dear all, This is my first time being here. I am doing a project related to sound and movement. Basically, the sound source is constantly moving back and forth. By theory, this would changes the frequency and I would like to observe these changes. I have tried to record and analyze using frequency ...

Re: Set of basic effects

In principle, I share Gale' and Peter's opinion. Those that I would hide were all spectral effects because they take away three "Valuable" places starting with "s". The main reason is that they do not fit in the concept and are 90 % of the time not useable. Furthermore, they could be simplified by e...

Re: factor db

Thank you. Thus we choose the value of the factor after all to avoid of the saturation.It is thus necessary to think of the following equivalences:lfff = 12 db = ...? (peak), lff = 9.0 dB = 4.0, lf = 6.0 dB = 2.0, lmp = -3.0 dB = ...?, lp = -6.0 dB = 0.5,lpp = -9.0 dB = 0.25, lppp = -12 dB = 0.125....

Re: factor db

Hello. I try to use the scale-db function: (scale-db db sound) [LISP] "db" is the factor. In this code (defun note (pitch dur amp) (scale-db (- amp 12 )(osc pitch dur *table*))) (abs-env (seq (note c4 i lp) (note d4 i lpp) (note f4 i lmp) (note g4 i lmf) (note d4 q lf))) the factor is determined by...

Re: Experienced help with vocals removed

Yeah no prob. I've included youtube video's that contain the song.There are two versions of the song, the song it's self is the same just one song sung by an artist and the other sung by the voice actor. I say an artist because you don't know who she is with only one part of her name given. By arti...

Re: Experienced help with vocals removed

Depends on the type of song for if vocals can be easily removed completely, and the song I have is that kind. And someone may be abledo it for me, I prefer to be positive and ask for help when I have done all I can myself. I have spent hours and days on this myself. There are some people who like a...

Re: Problems with the new Noise Reduction replacing Noise Re

I suggest Noise Reduction Of The Beast 6,6,6 should be default with a valuable variation being 12,6,6. I've used that multiple times now with various posters' difficult productions and high, sometimes startling success. That would put frequency smoothing default at the right extreme of the scale, w...

Re: Audacity and note determination

Yes. Well, you can essentially do anything what's possible with e.g. C++. The only restrictions are: - execution time-- probably not so important for non-realtime. - poor GUI support (you have to enter the saving path directly into a text box, there's no save dialog available) - You have to write t...

Re: Extracting the Center Channel - possible in Audacity?

Thanks, Robert. I've attached a version corrected for "plugin" without the hyphen. I forgot to correct it to the new nomenclature. I try to write it connected for the most time, although I hate that my screen reader says "Ploodjin" ;) I like the text changes and am happy with the action order now t...
