Mr.Y Posted January 2, 2013 Share Posted January 2, 2013 Have you tried resampling with foobar2000? I've discovered this function some days ago and the changes are clearly audible. I can't find any simple explanation about the differences between the most popular resamplers - PPHS (which is built in foobar2k) and the SSRC X resampler. Which is theretically better? To my ears PPHS at 96khz + ultra mode is the best - makes the sound fuller, meatier and with slight analog-like roll-off in the treble.

John Doe Posted January 2, 2013 Share Posted January 2, 2013 there is a special version of the secret Rabbit code resampler. but it's not the one you will find on their homepage, it's an older one a bit difficult to find. i have it included in my audiophile win8 project... -> http://www.computeraudiophile.com/f11-software/iso-usb-key-installer-preconfigured-and-stripped-down-audiophile-version-windows-8-pro-including-jriver-and-foobar-14390/ __________________________________________________ www.highend-audiopc.com | [email protected] Link to comment

donunus Posted July 1, 2013 Share Posted July 1, 2013 Can anyone explain how to read the values at SRC Comparisons? Sure I can understand the ones with a target value but for the graphical ones like the sweep tests here, what do we look for? one solid curve with a black background or one with all the fine lines still intact?[h=1][/h] Link to comment
Miska Posted July 3, 2013 Share Posted July 3, 2013 Can anyone explain how to read the values at SRC Comparisons? Sure I can understand the ones with a target value but for the graphical ones like the sweep tests here, what do we look for? one solid curve with a black background or one with all the fine lines still intact?[h=1][/h] Click the help-link on the page for instructions. But here's really condensed one... Sweep: Check that there's no frequency content below 20 kHz after sweep has reached 22 kHz point at around 5 sec, so after that point 0 - 20 kHz range should be black. 1 kHz tone: Check that there's only a single peak at 1 kHz and nothing else. If there's something, check how high levels of those other peaks are and if they indicate harmonics of 1 kHz. Passband: Check that frequency response is flat to around 20 kHz. Transition: Check that the response drops outside of the figure by 24.1 kHz, there should be absolutely nothing above that frequency. Phase: You can see the phase response, for linear phase it is straight line. For others you can see if the filter is minimum phase or some variant between the two. Impulse: Check for a short as possible impulse response. At least ringing should stay within the graph. It is easy to make a "perfect" filter if one doesn't consider impulse length (amount of time-domain smear) at all. Making it very short while having all the other parts excellent at the same time is challenging. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
donunus Posted July 3, 2013 Share Posted July 3, 2013 So would you say that SSRC is a decent free resampler? After 5 on SSRC theres not much info so far as the sweep is concerned but it is blue instead of black. Anyway, What would you recommend is the most accurate free resampler that one can use in real time for a music player like foobar for instance. Link to comment

donunus Posted July 4, 2013 Share Posted July 4, 2013 How do you set up Sox? Do you set it to 99% Passband? Are there any other good free ones to be used for foobar for upsampling? Link to comment
yamamoto2002 Posted July 7, 2013 Share Posted July 7, 2013 SoX 99% passband setting is a bit too much, impulse response becomes too long and it causes slightly muddy sound. Default bandwidth setting (95%) produces better sound. SoX webpage has a FAQ and it has a brief article for parameter settings. Sunday programmer since 1985 Developer of PlayPcmWin Link to comment
ronalde Posted December 12, 2013 Share Posted December 12, 2013 So would you say that SSRC is a decent free resampler? It surely is more than decent. For John Philipps ssrc is the clear winner, compared to sr-convert, sox, sndfile-resample (libsamplerate), audacity and resampaudio (afsp). Klaus (aka soundcheck) prefers sox over ssrc. He published some interesting comparisons between the two, especially with regards to ringing artifacts which SRC Comparisons from Infinitewave lacks. I published packages (debs) for installing ssrc on Ubuntu and Debian, so could easily try ssrc yourself. Regards, Ronald Link to comment
Tyimo Posted January 1, 2014 Share Posted January 1, 2014 Hi and Happy New Year! I tried the SOX 0.8.3 with my foobar2000 1.1.15 and 1.2.9, but it not works. The "console" screen not shows. I also tried the the built in Resampler PPHS and it is not working either. I tried the SSRCX and it works correctly. Could somebody tell me what is the problem with the SoX and the PPHS Resampler???? Are they not compatible with newer foobars? Tyimo Link to comment
serendipitydawg Posted January 1, 2014 Share Posted January 1, 2014 Tyimo, you already knew the answer! Your assumption in your last sentence (highlighted) was correct. Sox is compatible with foobar from version 1.0 onward. Update you foobar and all will be well! Hi and Happy New Year! I tried the SOX 0.8.3 with my foobar2000 1.1.15 and 1.2.9, but it not works.

You wrote "Sox is compatible with foobar from version 1.0", but I use foobar 1.1.15 and 1.2.9, versions. They are over the 1.0, but it does not work. what should I update in foobar??

Greets: Tyimo SoX Resampler component (regular one as well as 2 modded ones) works just fine with foobar2000 v.1.2.x & 1.3.x (you may need to unzip the component packages prior to adding them to earlier foobar2000 releases). Don't forget to add the desired Sox Resampler(s) to your DSP list. Link to comment

Matias Posted December 25, 2017 Share Posted December 25, 2017 @Mr.Y I also suggest you to try Ressampler V for foobar.
