Re: mathematical functions in audacity

You can of course first save the sign of the samples and then multiply it with the raised x from Steve's code (but with '(s-abs x)' (setf sign (mult s (recip s))) Either way, the function simply additional harmonics. The increase in pitch is most apparent when you take the power (setf s (prod s s)) ...

Re: erasing parts of a track without everything else moving

By the way, version 2.0.6 has two new commands in the track drop down menu--move to top and move to bottom.
If you use them smartly, there won't be the necessity to move the tracks hundreds of times up and down.

Re: How To Determine File Format

FFmpeg 2.2.2 supports QCELP and G.729, at least. If you had used MediaInfo as Gunnar suggested, we could have seen the information provided as to the exact codec and container. However you should get the version of MediaInfo without the installer, because the installer can be confusing or dangerous...

Re: Name this forum!

OK, so let's have "po-tay-to" ;) Audiobook Production Narrating and Producing Audiobooks. Why don't you use "Creating" anywhere? Is this word anyhow forbidden in English? (e.g. The lord as creator of the universe and audio books :D ) The title is appropriate as it is. The subtit...

Re: Importing Files and Quality

The quality loss is on the export side (encoding), not on the import one (decoding). The imported track exhibits the same quality as the playback in any audio player does. Thus, if you hear problems while playing the file, those will be passed to Audacity as well. The goal is to keep the quality lev...

Re: Standard gap between regions

Robert -- I successfully installed your plugin. This is great. Each message is separated by whatever time I'd like. However, they're all still on individual tracks. Should I put all regions on one track? Or is there a better way to do this? In general, multi Track is the way to go. The export mixes...

Re: Center-panned vocal isolation

The trick to better de-mixing of Beatles tracks is that you FIRST have to fix the azimuth. On almost all the Beatles song (remastered ones for sure) the left and right channels are not perfectly in sync. One channel is always 1 digital sample offset from the other channel, sometimes 2. Money is 6 s...

Re: Windfarms & ETSU-R-97 tonality checking

Jules thanks - let me have a go and I'll come back to you - really appreciate the help Jules? No, have a look at https://ccrma.stanford.edu/~jos/ Anyway, that's irrelevant for now. Let's simulate the first part of the method. Our sample sound could be narrow-band noise (400 - 500 Hz) with a gradual...
