Also why do you think he uses this barely audible frequency?

Because he's attempting to create "Subliminal Stimuli"

Why? the look-ahead buffer must have enough information to perform a very short stft. Given that fft_size=2048 samples and overlap/add=512samples I need fft_size+3*overlap/add=3584samples to calculate a single time frame, given that my sampling rate is 48000 the delay is 75ms. I am not sure how lar...

Check that the "Environment Variable" for WxWidgets is actually set. To make the setting stick, set the variable via advanced system settings (run SystemPropertiesAdvanced.exe). Under the advanced tab select the environment variables button and create new variables for wxWidgets. You may a...

I am interested in soft real-time, where a delay of up a few hundred ms is acceptable. That's how Audacity does "real-time preview", though I think for this effect you will probably need more than a few hundred ms. I will find a quiet zone at the start of the signal and use it as the nois...

Yes you can export directly to MP3, but it is highly recommended to also export a backup copy in WAV format. If you find that ...

Dropouts are frequently accompanied by clicks and pops where the dropouts occur.
Have you tried these suggestions (the first is probably the most common cause of dropouts on Macs): https://manual.audacityteam.org/man/faq ... ac_crackle

but will just stop selecting the previous recording prior to the next recording. If you know the duration of the second side before you start recording, you can make a selection of the right length (plus a bit extra for safety), and the recording will stop automatically (very handy for those times ...
