You can download it from the 3.99.5y thread.

Thanks for wanting to give it a try.

I decided out of interest that I'd try a different high performance MP3 encoder on this sample, and one that I've used before (when I didn't care about gapless features that LAME provides).

I encoded using Helix VBR at around 131 kbps, using settings -X2 -U2 -V60 which are the same settings used in the 128 kbps MP3 public listening test where it tied with LAME. The resulting encode is attached to this message.

I started out easily, but my tiredness set in and I lost concentration getting it wrong twice in a row. I carried on to 10 tests with renewed focus, getting all the rest correct, and I'm convinced I could genuinely detect the same sort of wavering I ABXed with lame -V 5 above, but which was fixed using lame 3.99.5y -V 5+ above

I'm not sure whether LAME or Helix is better or worse on this sample and I'm not that bothered.

I note that there is a short-block threshold switch in Helix, but not something specific to increase bitrate in short blocks, so it's unlikely that any commandline tweaks would fix it - except by using long blocks, which would mess up the picking transients (and not from the full help either).
