Has someone tested the cheby option of soxr lib ?
Hi friends

has someone tested the cheby option of soxr lib ?

The parameter in streams.options is the following

convOut=-af aresample=resampler=soxr:precision=28:cheby=1

The impact is (according to ffmpeg web site) :
For soxr only, selects passband rolloff none (Chebyshev) & higher-precision approximation for ’irrational’ ratios

Chebyshev polynomial are supposed to provide better interpolation than zero padding plus passband filter.

(Simon, do you need to restart the server when you change this parameter ?)


Unfortunatly, I had to leave my top end equipment in France while I am temporarly in San Francisco, so I can't really test :-(

Cheers
