Audacity Forum

We can only help you with the "Audacity" aspects of your question (unless someone on the forum has the exact same hardware and has done it themselves). What is the exact format that you require? Example: "MP3, 64kbps, mono, CBR" What is the size / length limit for the required fi...

Waveform view only sees sound down to about -25dB to -30dB before it becomes undetermined (invisible).

Unless you zoom in vertically

Audacity does not do real time effects. If you need real time effects, you could try "Reaper".

If you were to use MATLAB or similar, you would need to devise an algorithm to determine the start and end of the attack phase. In the "0dn_cnt.wav" example, the attack phase is easy to see, but to define an algorithm is very much more complex. We can see it your example that the "nat...

I'm thinking that this is one shortcut that we should probably move into the reduced Standard shortcut set.

I agree. It is definitely one shortcut that I miss if I don't have the full set enabled. Several other people have also written in about the "loss" of this shortcut.

Are you sure that's right? 1) What happens if you have: a carrier frequency of 1000000000 Hz two audio frequencies at 100 Hz and 200 Hz a Doppler shift of the carrier to 999999900 Hz 2) What would happen if there was a Doppler shift of the carrier to 500000000 Hz (100 MHz to 50 MHz)? 3) If I was lis...

If you mean the "Ctrl + i" ("split") shortcut, it is in the "full" set of defaults. See: https://manual.audacityteam.org/man/key ... l#defaults

What is the purpose of this?
Why don't you care if the effect works? (If you really don't care if it works or not, why bother running the batch at all?)

In this particular case, I was simply chopping off a few seconds of silence at the head of a FLAC file. Pretty sure the dither added by Audacity would be of no benefit in this case. Correct. As you suggested in your previous post, the way that Audacity handles dither is not ideal in all cases, but ...

Easiest to see if you " Normalize " the track first. Select the "attack" (rising) section, then read the length from the Selection Toolbar . As you can see in this screenshot, the attack starts at around 7 ms from the start of the track and has a duration of around 36 ms. attack....
