to me, but not quite. There was a teensy-weensy difference with the sinc-

I also listened with speakers and two different style headphones, including
one studio monitor type.
Thanks. It was the playback.
Is your resampler published? I'd like to try it. Since the resampling
turned out to be possible, I will probably use this setup for Vinyl->CD
conversion; and I'd like to have as good a resampler as possible.
I agree with Erik that this ringing and distortion
must come from your
sound card or driver setup and additional sample-rate conversions or
something like that, not from the sinc-based resampling. I am not a
big fan of sinc-based resampling for fixed-rate conversions, so I would
tell you if there was anything bad. I don't hear anything unacceptable
at all --- other than that the source is very noisy! That's going to
be hard to clean without noticeable artifacts based on some cleaning
I've done in the past (Windows-based, not Linux). So I wish you good
luck.
The source is very noisy because that particular recording is a
grammophone one made around 1930, then copied with some cleaning to new
vinyl around 1980. It's DOUBLE mechanical recording noise.
