Re: [Audacity-devel] Patch for TruncateSilence effect

[James C. <cr...@in...>]

Philip,

Thank you so much for this patch! I was particularly pleased to see:

+   // Stress-test the logic for cutting samples through block endpoints
+   //blockLen /= 8;

...glad that you left that in as a comment.  The changes are well 
motivated too.  My apologies that it is likely to take longer than it 
should for this and for the previous compressor patch to work their way 
into betas and the stable release.


--James.
