SoX Resampler (VHQ)
r8brain (Pro)

SSRC (HP) tuned by EAC3TO
SSRC (HP)

Secret Rabbit Code (libsamplerate) tuned by ReClock
Secret Rabbit Code (libsamplerate)

Wich of this resamplers have you tried, what you can reccomend? I need it mostly for NTSC/PAL (4% slowdown/speedup) conversions.

I have found this page (wich have most of this methods listed), but still not sure what will the best for movies (48 kHz, AC3 artefacts).

Don't use resamplers often, but curious to know some things...

Let's say you want to downsample a 24-bit/96kHz file to 16-bit/44kHz,

When using SoX plugin with foobar2000 to do the conversion, SoX plugin does not have any dither settings so you cannot also apply dither ...is this correct?
When using SoX from the command line you can resample AND apply dither if you want ...is this correct?

Considering that the thread topic is Best quality resampling method, what is the best way of applying dither using SoX (as plugin and as standalone)?
I get asked questions like "SoX is a great resampler but I also want it to apply great dither, how?" all the time (because I happen to use foobar2000 a lot), but I can't give authoritative answers.

Changing the bits/sample isn't resampling smile.gif

Why not just use the (very good) built in foobar2000 dither? Any quality dither should give you transparent results if the output is at least 16 bit.
