 Starting as a hobby
project in 1998 and designed to achieve quality MP3 encoding at
higher bitrates, Tord Jansson downloaded the ISO source for MP3
encoders and went to work on what would become BladeEnc.
Tord felt the need to deliver software that was free to use and
let BladeEnc develop into an Open Source project. However,
since the encoder was based on the ISO source code that
Fraunhofer-Gesellschaft and other MPEG Layer III companies help
patents on, Jansson was forced to discontinue distributing
BladeEnc in executable form. However, compiled versions of
BladeEnc are still floating around for you to search for (we
don't post any links here as to avoid any difficulties with
mentioned parties). The source
code for the program is available however under LGPL
license.
BladeEnc achieves very good quality even if it is
a bit on the slow side (see Jansson's commentary on MP3
encoding speed) other work is being done to improve
this. Format is command line, as shown in the screenshot
above, but other programmers have built graphical and console
interfaces to make BladeEnc more user friendly for the all of us
command-line inept. BladeEnc is also packaged with many
other MP3 software packages.
Technical Information:
BladeEnc.dll and BladeEnc.exe:
-
Stereo or Mono
output. Can downmix to Mono on the fly.
-
Supports the
following bitrates: 32, 40, 48, 56, 64, 80, 96, 112, 128,
160, 192, 224, 256 and 320 kBit/s. However, for bitrates
lower than 128 kBit we seriously recommend you to use
another encoder.
-
Flags like
Private, Original and Copyright can be set.
-
Input samples
can be in either 32, 44.1 or 48 kHz.
-
Both 8 and
16-bit samples are supported.
-
Working CRC
checksum generation (since 0.80). The ISO reference code had
broken CRC calculations, which has been inherited into every
ISO based encoder that haven't added a fix for it.
BladeEnc.DLL:
-
Can be plugged
directly into many popular 3rd party products, giving them
integrated mp3 encoding abilities.
-
Encodes chunks
of data from memory to memory, no need to use files or
pipes.
BladeEnc.exe:
-
Can be compiled
for nearly any operating system still in use.
-
Commandline
based, makes it easy to include BladeEnc into BAT files and
shell scripts.
-
Only mp3 encoder
that supports gapless encoding.
-
Reads standard
uncompressed WAV- and AIFF-files as well as well as RAW PCM-data.
-
Batch encoding.
Can encode any number of samples in a row.
-
Wildcards
supported. You can for example encode all WAV-files in a
directory by typing "*.WAV".
-
Input samples
can be automatically deleted after encoding.
-
Large selection
of graphical frontends available.
-
Task priority
can be set from the commandline and is by default set to
LOWEST so that you still can use your computer effectively
while encoding (Windows & OS/2 only).
-
Textbased
configuration file where you can change default settings.
