INTRODUCTION

A file conversion tool for translating dsf or dff dsd audio files into
flac pcm audio files.

I originally wrote this because I could not quite find any tool which
did exactly what I wanted.

I program quite a lot in java and I'm pretty good at matlab. Although I've
very occasionally written things in C and CPP, this is really my first attempt
at a full CPP program. I'm sure there are errors, hopefully none to horrible.

I've tried to write things in a pretty versatile/clear way. It should be possible
to expand the functionality to add other file types quite easily.

If you want to try different conversion filters then it should be dead simple:
just look in filters.cpp.


COMPILING

I developed and tested this program on Linux x86_64 with GCC. It probably compiles and
works on x86 GCC too. Windows might be a bit more work.

I've added a cmake build configuration which works on Linux and should be relatively easy to
adapt for other platforms.

Usage:

mkdir build
cd build
cmake ..
make




If you want to try manual compilation then you'll need to link against these libs:

FLAC++
FLAC
boost_system
boost_timer
boost_filesystem
boost_chrono
id3
z
rt
ogg


RUNNING

If you run "dsf2flac -h" you'll get a list of the options.

At the very simplest level you just need to run
"dsf2flac -i some_audio_file.dsf"


BENCHMARK

I was quite pleased with the performance.
For example, with the default filters (which are quite long) the program
will convert and encode from DSD64 to 24bit 88200Hz flac at around 
14x realtime on my ageing laptop (Intel Core2Duo P8600@2.40GHz)
