General Audio / Re: Need some advice on resampling 192Khz/32bit float.
Last post by Case -I was noticing clicks right at the beginning of resampled files (SoX). [...] Double clicking on the file in fb2k gives a tiny click.As Wombat replied, resampling didn't cause this issue. A track that doesn't start with silence will click when played alone. In foobar2000 you could use Fade In/Out DSP with 50 ms fades and the track change detection disabled and it would take care of potential click like this when playback starts and ends.
But for this particular track a better fix would probably be to get rid of the DC offset, if possible. And at least this track seems to try to start fading from silence, so you could simply force the track beginnings and ends to fade to silence even with the above mentioned Fade In/Out DSP (this time with track change checks left enabled) or with Fake Gapless DSP.
@Raven1 I recommend you to never divide frequencies by non-integer factors (for 192 you should target 48 instead of 44, for example).As Wombat replied, this is nonsensical myth that has no basis in reality. For reference I tested with 32-bit foobar2000 that uses just 32-bit math to resample 192 kHz first to directly 48 kHz and compared that against a track that was first resampled to 176.4 kHz (which is a multiple of 44.1 kHz) and then to 48 kHz. Even though one of the tracks was resampled twice the highest sample difference was at -133.62 dBFS and average RMS of the difference signal is -166.08 dBFS.
The non-integer resampling ratio or even multiple resamplings are a non-issue, the introduced error is so tiny that even measuring it isn't simple and absolutely no playback equipment will be accurate enough to play them differently.
Edit: fixed typoed Wombat's nick.
