[Flac] Feature request FLAC

[Devon Holcombe]

I vote for #2. 

I don't see the options in #1 as strictly going with the philosophy of FLAC
being a lossless codec although neither one seems like a bad idea if
implemented properly. More generally part b of #1 would allow you to select
any channel(s) from a source and just encode those channels. For example you
may want to encode only 3 channels of a 4 channel source or 5 of 8 or 1 of
8, etc. This seems like it would be the best way to do things, given what I
know of the current FLAC architecture.

I started fiddling with trying to learn some FLAC development a year or 2
ago, but unfortunately I have never really found the time and haven't
touched it since. Between school and work I already don't get out much or I
might be interested in doing #2. Alas, maybe when I finish grad school in a
couple years if nobody has gotten around to it.

Is there a proper etiquette for posting to this list as far as top post,
bottom post, partial quote, etc?

Dear all,

I am an active FLAC user and like the program a lot! Thanks for your
great work. Since I am not a developer I cannot modify the program on my
own.

Maybe you might be interested in features I would find useful. Maybe others
find them interesting as well and you find the time to implement them.

1. Add encoder options:
a) Skip silence (leading and ending) would give the option to skip silence
at the beginning and end of WAV-File. Currently I have to use an external
program (WavTrim) to do the job.
b) Convert to mono: I encode a lot of audio books from CD. While in reality
they are only mono (one person reading) the are transferred as stereo from
the CD. Converting them to mono greatly increases overall compression.
Currently I have to use SoX for conversion which is slow and painfull.
Better would be to have an option in FLAC to skip one channel and encode the
other channel as mono (as seen in LAME)

2. Develop DLL for EAC
I use Exact Audio Copy (EAC) for CD ripping. It would be great to have an
DLL (as in Monkeysaudio) to directly rip to FLAC and not have a WAV-file as
intermediate

3. Album-gain based on individual replay-gain values
I encode each file with an replay-gain value. If I want to add album-gain
values with metaflac all files are analyzed again. Could the album gain
value be calculated by using existing track gain values for the individual
files. This operation would be much faster.

Do you find this suggestions interesting?

Regards,
Alexander
