Is this to get a reference on the speed difference "cygwin vs native"? Hmm... it has no GUI, so it is "cmd" version, if anything :-) (Though there seems to be separate gui frontends available) All prebuilt binaries are from 2001. Just as the source; it seems to have been stale since then. Same P2/450 again - as always: -- ... Encoding: B5_SoLong.wav Input: 44.1 kHz, 16 bit, stereo. Output: 128 kBit, stereo. Completed. Encoding time: 00:01:12 (2.54X) -- The output is exactly the same amount of bytes. But md5sums differ on three of the mp3's. Probably due to diffrent "c.o"++ > How fast is it compared with the Cygwin version? Answer: Approximately 20-40% faster in "cmd native mode" IMO the better "compatibility" with the other cygwin tools is worth more than the extra speed. This of course reflects that I mostly encode my own LP records, at most one per week. For archiving - and to be able to create CD copies for my personal use. (I see the LP's as "collectors items" - i.e. I use them as little as possible). Hmm... As I looked for that prebuilt binary I found a DLL version of the encoder. I wonder what difference it would make to have a cygwin "frontend" based on that... Well, I think I'll let that be a future project. /Hannu E K Nevalainen, B.Sc.
