Re: Silent Subliminals without background

What's with all the subliminal messages posts lately?! :roll: Wonder if they are trying to tell us something... Damien The German Forum is even more floated with this kind of questions. There can also some plug-ins and snippets be found. Maybe we could incorporate the trend and replace dithering wi...

Re: Audacity Plot Spectrum

The plot shows the correct frequency range. Low frequencies are poorly represented in FFT's of only 128 samples. Divide the sample rate by half the size and you know how much the "bins" are apart: 8000/64 = 120 Hz. The lowest bin is at DC (= positive or negative offset of the waveform). Th...

Re: Append Import

You could also try my Plug-in: http://forum.audacityteam.org/viewtopic.php?p=190928#p190928 You import the files via the import menu. Select all tracks and start the plug-in. For a pause of 300 ms just enter 0.3 in the gap control. Once the tracks are arranged, you can mix them down or simply export...

Re: plugin for podcasting/radio show sound effects?

I recall that the RamonNoodle (Audacity2Podcast - where Chris' Dynamic processor is hosted) has made a comparison of such sound effect players. If I am not mistaken, Pod Producer is one of those. The podcast is a little bit older (~2011) and I guess that there has been some development and some new ...

Re: Decrease volume by x% (with Amplify)?

You can use the Nyquist prompt. and multiply the sound with a constant.
1 is equal to the momentary value or 100%. So, if you want to reduce by 10%, you can set the constant to 90 / 100 = 0.9.

Code: Select all

(mult 0.9 s)

Re: Submit your EQ Curves

Thanks a lot.
Nice compilation. Took me a while to activate the new curves. The management is somewhat strange - especially if you do not change your curves regularly. However, they are now present and I'll see if they are useful to me.

For partial seconds you can also write:

Code: Select all

(setq silence-duration (real-random 10.0 50.0))

Re: Center-panned vocal isolation

Pretty complicated the whole Fourier stuff. I'm impressed :grin: I was wondering why we had not heard much from you for a while. I'm looking forward to seeing your code. The subject is quite absorbing. Hundreds of pages to read in order to aquire another little bit of useless knowledge - in the sen...

Re: Center-panned vocal isolation

Fantastic Robert. As you say, the results for centre removal don't sound much different to the simple invert and add method, but it's terrific that you got this working. There may be a slight problem with your windowing function - I can hear a slight clicking, which on close inspection is every 409...

Re: Isolating speech from movie

My tool is currently under development. It should be available during the next week. However, as I've mentioned, just making the audio mono gives a fairly good result. I've recorded the video stream directly within Audacity. Make sure that the Audio is recorded (or downloaded) in stereo. Normalize o...
