Re: Special kind of frequency sweep (chirp)?

Do you know anything about the construction of the Thunderbolt?
I'm guessing that it has a dual rotor with 12 blades and 10 blades.

Re: Too much treble : equalization doesn't helps...

Below 200 Hz there is only noise. The person speaking does not have a deep voice so there are no bass frequencies (other than noise) to bring out. I'd disagree about there being too much treble. There is too much low frequency noise, and frequencies in the range of about 400 to 500 Hz are overemphas...

Re: Multi-Track Amplify

Three very good reasons to use 32-bit float for multi-track projects: 1) Safeguard against clipping when mixing. 2) No dither noise when processing tracks. 3) With a lot of simultaneous tracks, the tracks will probably need to be at a very low level (to avoid clipping the mix). 32-bit float preserve...

Of course. With 37 tracks you wouldn't want 37 instances of quantize error would you?

Re: Razor blade off the first half-second.

With nimble enough fingers you can also click/drag and scroll down with the mouse wheel at the same time. My method: 1 Click in the first track at 0.5 seconds 2 hold down SHIFT, HOME, hold down DOWN ARROW, release SHIFT and DOWN ARROW. That's neat - I keep forgetting about SHIFT+Up/Down cursor key. ...

Re: Multi-Track Amplify

The way to do it manually (Windows/Linux shortcuts) 1) Ctrl+A (select All) 2) Ctrl+Shift+M (Mix to new track) 3) Select the new track 4) Open the Amplify effect and make a note of the default amplification amount (as an example, let's say that it is -23.6 dB) 5) Subtract 1 from that number (-24.6 dB...

Re: Multi-Track Amplify

Amplify adjusts all the selected tracks so the Stereo Mixdown comes out without overloading or clipping. With long tracks it would be slow. Audacity would need to calculate the peak amplitude of the mix (Audacity "knows" the peak amplitude of each track, but it does not know what the peak...

Re: Multi-Track Amplify

Interesting idea.

I think I prefer the idea of a "Master Fader" on the Mixer Board that moves all selected faders (and so all track gain sliders) in unison. This way would be non-destructive.
No reason that I can think of for not having both options.

Re: Razor blade off the first half-second.

You can click/drag across multiple tracks if they all fit onto one screen, but with 37 tracks they won't. The laborious method: Select the first half second of the top track Down arrow ENTER Down arrow ENTER Down arrow ENTER .... Delete The clever way: Create a 1/2 second region label below the bott...
