and the download (for mod version) gives me just a dll.

No, it should give you .zip file, and foobar2000 supports both .fb2k-component and .zip files.

Extrapolation feature seems to work nicely.

For the command line interface I'm using these parameters for resampling -G - rate -v -L <targetrate>
To be sure, is Ivqcl's plugin qualitywise up to pair with cmdline interface with used params and does the SoX utility provide the extrapolation feature?

Ivqcl's plugin is  up to pair with cmdline qualitywise with used params. (Passband: 95% (SoX default), Quality: Best, Allow aliasing: disabled, Phase response: 50% (linear)) But it doesn't provide guard against clipping (-G option). But are you able to hear clipping from resampling?
SoX commandline tool doesn't provide extrapolation feature.

Actually foobar2000 component wins the command line in quality. The command line interface can't do floats and suffers from unnecessary rounding and of course clipping. And if you use a parameter to prevent clipping you alter the volume.

Just want to say thanks for this component. Been meaning to check it out for ages, and it works exactly how I need it to.

Background: I run a mastering studio where EVERYTHING (all DACs, PC, drivers and digital equipment) is clocked to the master capture ADC. To change the sample rate is a PITA as I have to go into my Crookwood mastering console's menu settings multiple layers to do it. Every time I want to audition a quick 22k mp3, or enjoy listening to 192kHz Norah Jones albums, for example, it's a bit of a hassle to go hardware menu diving just to be able to do so. So I have been wondering for ages how I could keep things at 44.1 (my usual) but have those different SRs be automatically converted to 44 on the fly (I know it's not the best quality conversion, I go offline SRC for that in mastering duties with FinalCD or iZotpe RX7 Advanced). Now, thanks to the Mod2 version, I can specify that all those other SRs are real time converted to 44.1 and I can listen quickly without having to dick around.

THANK YOU! I wish I had sorted it out much earlier...

@darkflame23 : If you want to resample everything to one single frequency, then you don't need the "mod2" version?
I use the mod2 in order to select for upsampling files of unsupported sampling frequency, but I do not want to spend that weak computer's CPU load on resampling when I don't have to.

(My "ideal" component would intercept an "unsupported" error message and only then start resampling, but I don't switch output device when I don't have to.)

Version 0.8.4 is available (see the 1st post).

Ivqcl:  Thank you for the update, mod2 is one of my "essential" plugins.

Thank you for an update of this very fast and transparent SRC, for me unique in that it's suitable for real time playback conversion and imo very high quality offline conversion.
Shame it has not yet been added into components catalog.

Possible bug with v. 0.8.5
Options for 2x/4x upsampling are not saved. After adjusting one of the upsampling values, confirming with "OK" and subsequent plugin options window opening, there stays "1000".

@jaro1 Thanks, should be fixed in 0.8.6.

@lvqcl

mod link still points to 0.8.4 ...

Re: Resampler plugin

No reason to update them. The bug was introduced in 0.8.5, so they weren't affected.

@lvqcl version 0.8.6 is not available for fb2k?

Hi lvqcl, thanks for the awesome software! Do you know how long the filter is for x8 oversampling? Would we get better performance with an even longer filter?

Have no idea.

Why? It can be worse, not better.

I know SSRC is 16k max, if that's useful. It is often suggested that longer filters are more accurate, though more computation-intensive. Why do you think longer filters can be worse given the same design?

Re: Resampler plugin

I thought that "performance" means speed, not accuracy.
There's no need for better accuracy, because SoX quality is already excellent.

Re: Resampler plugin

Longer filters can lead to more pre- and/or post-echo or ringing. The current filter design is already sufficient for mathematical accuracy, which is already way more than you'll ever need for audible accuracy.
