Summary: TOOLS: extract with high quality resampling
Initial Comment:
Ogg Vorbis is a very nice codec in deed and the OGGENC
does a very good job as well. But when it comes to
resampling the input sample the results are very bad.
The build in low-pass-filter is very simple and heavily
reduces the frequency response in the resulting encoded
file. (The optional low-pass option does not change
this, as I tried it already.) So it would be very nice,
if EXTRACT could do the resampling with an external
tool like sr-convert (see here:
https://sourceforge.net/projects/sr-convert/ ) before
encoding with OGGENC.
This should of course not be forced, but an option,
since this high quality resampling takes a lot time.
Alternatively, since sr-convert also is open-source,
you could include that high-quality resampling into
extract itself.
However, there is one little catch: sr-convert does not
read 11111 Hz, but this should be implemented easily.
Or EXTRACT could make it 11025 instead as an approximation.
