TOOLS: extract with high quality resampling
|Reported by:||SF/logicdeluxe||Owned by:||fingolfin|
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.
