Currently, the Makefile hardcodes things like compiler optimisation or installation path.

It would be nice, if especially CXXFLAGS and PREFIX could be set to different values. This should be doable by using := instead of = for default or suggested values and then using += for required values (i.e. compiler flags specific to this project like some -D or so).

Additionally, it would be nice if the Makefile variable DESTDIR would be support. It's a prefix to PREFIX only in use at installation time so that you can call make install without being root despite targeting for a later installation as root. This is quite common when building binary software packages for distributions.

See my current patch in the Debian package to get an idea of what I think of.

VLevel v0.5

usage:
        vlevel-bin [options] < infile > outfile
[…]

That vlevel-bin also doesn't look right, btw.

It will be me as ladspa plugins often bamboozle me

arecord -Dvlevel -r16000 -fS16_LE -c2 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Stereo
arecord: set_params:1347: Access type not available

pcm.vlevel {
    type ladspa
    slave.pcm "plughw:0";
    path "/usr/local/lib/ladspa/";
    plugins [{
        label vlevel_stereo
        input {
            controls [ 2 8 20 ]
        }
    }]
}

If you could just post how the pcm should be, likely better :)

I'd like to apply vlevel to a file of mine. I'm pretty sure this will be simple enough to do, but could you provide some hints?

Use case: I download podcasts from the Internet, then I put them into USB sticks which I'll then plug into my car radio. I'd like to apply vlevel to that!

I'm pretty sure this would be possible (with some sox-magic, maybe?) but having some doc, or even a readymade script will be great! Bonus points if that preserves metadata :)
