Re: request for cube waveform 441

A fractal-ish square-wave would be possible : with crenelations on the horizontal parts, which themselves had smaller crenelations on the horizontal parts of the crenelations, which themselves had even smaller crenelations on the horizontal parts ... etc, etc , [similar to Koch Snowflake , but squar...

If you post 5 seconds of each track [matching] we should be able to tell you if extraction of percussion is possible.

There are programs which will convert an image into a spectrogram.
You could use an image of a fractal as a spectrogram, e.g. ...

Re: request for cube waveform 441

Some fractal audio waveforms are possible, but they are monotonous. They just have the peculiar property that they sound unusually constant when being played at different speeds, e.g. shepard tone .

Re: Extract percussion from song

The inversion method only works if the tracks are perfectly identical and exactly in anti-phase.
Otherwise try spectral-subtraction method, e.g. RJH stereo tool or Kn0ck0ut , which does not require absolute precision , ( spectral-subtraction method does add digital artifacts :( ).

Re: How do i make this effect

... some kind of gradual/gain filter... I think the "gradual" thing is an automated high*-pass [HP] filter which sweeps from 1KHz to 0 in two seconds. There are free VST plugins which do that, e.g ... https://youtu.be/tNhb3N9U4dM?t=1m27s Sweeping High-Pass filter demo.flac [ * Audacity's ...

Re: Windows 7 - Audacity - No Infrasound EQ

In the past I've seen an Audacity No Infrasound EQ "No Infrasound" was my name for a high-pass filter, ( a/k/a/ bass roll-off), which removes inaudible infrasound . ,,, I can't find it now. Any help? For some reason my "No Infrasound" post is off limits at the moment ... http://...

Re: Creating Basic Audio & Video Recordings

We know from posters that the sampling rates of different recorders can vary from each other enough to create lip-sync problems on medium or long shows ... I was suggesting a method of optimising the audio on the video, (which retains synchronisation) , rather than transplanting audio recorded on a...
