Re: Audacity Spectrum Generation and Python

I've been trying to remember the name of the automation tool I used a while back (to automate a job in Audacity) - just remembered :)
Actionaz (https://www.jmgr.net/)
Ubuntu and Debian both have it in their repositories.

Re: Audacity Spectrum Generation and Python

but my FFT analyses does not output the same graphs Are you comparing the (text) data, or just the (graphic) graph? The text data from Audacity is "scientifically" accurate, but how the graph is drawn is in part a matter of interpretation. There are many ways to interpolate / extrapolate,...

Re: Some problems, applying Bass and Treble.

How to see what the effects are just applied? Sometimes forget the sequence, was the effect applied or not. There was talk, but now I see only "repeat last effect". If it says "Repeat last effect", that means that you have not yet applied any effects during the current session. ...

Re: Audacity Spectrum Generation and Python

But instead of having to export the data, since that has to be done manually as far as I know, I want to automate the process :) Audacity does not have that feature built in, but some options are: * Use AutoKey, Sikuli or similar to automate Audacity via its GUI. * Build Audacity from the sourcecod...

Re: Dropout detection

Youtube user agreement 5.1(c) forbids me to use a downloader. I don't think it does. It forbids you to hack their server, but it permits access via their webpage interface, which is what a browser based plug-in is doing. More relevant is item 5.1(L) (emphasis mine - Terms of service may vary by cou...

Re: How to NOT avoid aliasing

What I want to do is to either generate a tone, or record a tone from a tuning fork, with the sampling frequency deliberately set too low, and show how this changes the frequency of the recorded tone. Here's a simple demonstration using the Nyquist Prompt effect (http://manual.audacityteam.org/man/...

Re: Further assistance

Hum is often best removed by filtering (assuming that you are not able to prevent the hum in the first place). If you post a short sample of unprocessed recording, in WAV format, including a couple of seconds of "silence" (noise/hum only) and a couple of seconds of speech (or whatever the ...

Re: Audacity records my gameplay

Can't anyone help me with this problem? You've given very little information to work on. Start with the exact version number of Audacity that you are using (look in "Help > About Audacity"). What sort of microphone are you using? Are you listening to game sounds while you play? If so, how...

Re: Dropout detection

Lets say this way: Digital cameras have a system to detect faulty pixels in the image sensor. The data about faulty pixels is used to clean the photos at earliest phase. In audio, dropouts may occur in many places. The A/D converter in a USB sound card is close to your analogy of a camera's image s...
