It is a matter of balance and tradeoffs.
--nspsytune allocates more bits to sounds with high tonality,
sacrificing sound quality with low tonality. I tuned parameters so that
--nspsytune -V4 produces mp3 files with almost same bitrate in avarage
using wav files on the LAME webpage.
So, if you want to improve sound quality with low tonality, simply
raise bitrate.
I think --nspsytune gives better balance of bit allocation with
tonality. This can be tested by comparing sound quality with following
settings:
1. Use lame compiled with Robert's options turned on.
Command line options are:
-h (or -q1) -b 96 --resample 44.1 --lowpass 16 -Y -Z -X1
2. Use lame compiled with default options.
Command line options are:
-h (or -q1) -b 96 --resample 44.1 --lowpass 16 --nspsytune
With these extreme settings, I can hear more artifacts with 1 than 2.
