Hi Robert.
Hopefully someone else can help with the Win32 compile - please :)
I think Marks suggestion of using a width option may be less confusing and
easier to use.
As far as radio is concerned, the 2 main presets would be something like
this:
1. Music/commercials:
FM 50 - 15000 hz, stereo:
--lowpass 15000
--lowpass_width 0 (sharp cut-off)
-m j -b 128
Not sure whether a highpass at 50hz would be beneficial or not.
2. High quality voice (interviews etc). I'm not sure what the best settings
for this would be. I haven't analysed voice frequencies so I'm guessing at
the following:
HQvoice 200 - 10000 hz, mono:
--lowpass 10000
--highpass 200
-m m -b 64
Support for variable bit-rate should be added to the presets as well. If -v
is specified, an equivalent -V setting should be defaulted. I presume -V4
could be used for both of these. The -b settings would have to be increased
or removed.
Cheers,
Ross.
