Re: Higher order filters
Only one set can be right I don't think that is correct. By way of analogy, if you were creating these filters in hardware as capacitor-resistor networks, there are many alternative choices of values to produce the required filter. The important thing is that the set of values used produces the req...

Re: Higher order filters
The theory is explained here: http://www.earlevel.com/main/2016/09/29/cascading-filters/ You can try out different values yourself using Nyquist's BIQUAD ( or BIQUAD-M) functions: http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index460 The Biquad Calculator from the same site will help you determ...

Re: Higher order filters
I think the values used in Nyquist were tweaked by hand to give better approximations of the ideal filter characteristics than are achieved using the theoretically "correct" values. The frequency response and group delay of the Nyquist filters certainly appear to be pretty close to "i...

Re: Selection.
I'm not sure what you are trying to say. To move the cursor to the end, press the "End" key or the "Skip to End" button

Re: Batch find silences in talk radio programs
I'm looking for a batch process that will find silences (say, > 5 seconds) in mp3 files. What do you want to do with those that have silences? If you want to reduce the amount of silence, why not just use Truncate Silence in a Chain? (http://manual.audacityteam.org/man/truncate_silence.html) 1. Cre...

Re: ?'s about input volume and playback volume
Audacity 2.0.2, but will upgrade shortly :-) That's very old now. Audacity 2.1.3 is available from here: http://www.audacityteam.org/download/ 1. If I always set the input level to the same number on my microphone, will the output volume be the same? The level in Audacity when recording from a mic ...

Re: File keeps saving as 00h:02m:00:033s instead of 00h:02m:
"32-bit float" is the Audacity track format and unrelated to the MP3 format. The first thing that you should check is that the metadata for your files is correct. “Advert:” must be in both the artist and title sections https://www.shoutcast.com/FAQ If that doesn't fix it... Podcasts are us...
