Anyone tried FSRC http://libfsrc.sourceforge.net/? The tests shows good specs and I was surprised by its speed.
QUOTE FSRC (Overlap-Save) - ~5.6s FSRC (Polyphase) - ~16.1s libsamplerate - ~103.9s Any programmers who might be interested in making a Foobar2000 dsp of it if it's possible? I would like to try it out against SoX. Regards. |

QUOTE (Arnold B. Krueger @ Jul 30 2012, 11:43) AFAIK, one of the two tests I ran above (96k -> 44100) is the same as is run at the Infinite Wave site (they test only one ratio, and in only one direction). I ran each test twice, once on an 8-second sweep (as they do, though I chose a linear sweep; they use a quadratic) to generate the spectrograms, and once on several minutes of audio, for the execution-time measurement. Where possible, I used the same settings as Infinite Wave for each converter; but I don't know what settings were used there for libfsrc, apparently something with better stop-band rejection than "-q hq24", but I couldn't get anything higher than that (such as "-q push") to work. |
