Debug in Nyquist LevelSpeech2 outputs information beyond my cognitive domain

Audacity 3 Help Forum GNU/Linux

I often process youtube podcasts converted into audio format, upto 2 hours duration. I have sufficient RAM and minimum other programs open/running running to interfere with memory shortages.
Whereas in the present instance, the file is a mere 878.236906 = 14m38s236.906ms long audio file.

LevelSpeech2, with Leveling Amount 100%, Risetime default 0.02, falltime default 0.01, Limiter threshold 0.666 yields the following Debug data:
-24

The maximum number of sample blocks has been
reached, so audio computation must be terminated.
Probably, your program should not be retaining
so many samples in memory. You can get and set
the maximum using SND-SET-MAX-AUDIO-MEM.

This is beyond my domain. Mr. Steve, your advice is requested.

For speech, release (falltime) should be ~10x longer than attack (risetime).

Typical values for speech: attack 10ms (0.01), release 100ms (0.1)

But Mr. Trebor, I didn’t touch the values. They were default, as stated. Moreover, it works for all other files.
Thank you for replying to my post.

Defaults on LevelSpeech2 are 20ms (0.02) risetime, 100ms (0.1) falltime …

;control amount “Leveling amount (%)” real “” 75 0 100
;control risetime "risetime " real “” .02 0 2
;control falltime "falltime " real “” .1 0 2
;control threshlim "Limiter threshold " real “” .666 .1 1

There is a limit on how much audio Nyquist plugins will process in one go.

Does this file have a higher sample rate? Higher sample rate (kHz) means more data.

First of all, Belated apologies, falltime was 0.1, not 0.01, earlier typo, noted at 12:53 +0530 IST, so reported.

All files, same format. 32 float. 96KHz sampling rate, flac file format. No alteration from file to file. But Standard. For the ease of using Macro.
Thank you Mr. DVDdoug for interacting with me.
