request: option to trim silence from beginning of subsong about gbsplay HOT 6 CLOSED

Do you have examples of gbs files with a significant amount of silence at the beginning of a subsong?

from gbsplay.

not anymore. it would be possible to script something up to find some examples, comparing the length before and after sox trims the silence.

from gbsplay.

ihe script takes a lot longer to run that I thought, so here's the first couple of examples it found.

This one isn't pure silence in the beginning, but it's close enough:

Animal Breeder : track 14/62
120.000726 -> 109.915669

this one spews a bunch of warnings under gbsplay, and doesn't produce any audio, so it's all silence.
http://www.zophar.net/music/gbs/animastar-gb.html
Animastar GB : track 106/167
120.000726 -> 0.000000

from gbsplay.

The "silent" parts both have activity on the drum/noise channel, so I would not consider this 'silence'.

Animastar indeed throws warnings (but sounds alright nontheless), would this warrant a separate bug?

Seems to be a color game boy register:
FF70 - SVBK - CGB Mode Only - WRAM Bank

from gbsplay.

With some fixes in the meantime "Animastar GB : track 106/167" is no longer silent, it seems to be a SFX track with only noise happening.

Similar as mmitch said "Animal Breeder : track 14/62" starts with the noise channel.
