Code for converting DSF to FLAC files

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 convesion 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 compile and works on x86 GCC too. Windows might be a bit more work. If you are building statically you'll need to link against these libs:

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

However, only the following are required to build a dynamically linked library (which is probably the use case for most people):

FLAC++
boost_system
boost_timer
boost_filesystem
id3

Simply run ./autogen.sh if you have GNU autoconf and automake installed. If all goes well, it will generate and run configure which will execute successfully. If there are any errors such as missing development libraries, please fix them and re-run ./autogen.sh.

If everything went smoothly, you can now run make and src/dsf2flac should be generated. By default, the installation prefix is set to /usr/local, so sudo make install would install it in /usr/local/bin. However, the prefix can be overriden using the configure script after running autogen.sh. Simply run ./configure --prefix=/your/prefix/path. For more information, please see ./configure --help

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

Or you may play file directly via DSD capable sound card

dsf2flac -d -i "some_audio_file.dsf" -o - 2>/dev/null | ffmpeg -i - -c pcm_s32le  -f alsa hw:1

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 @2.4GHz)
