Features common for both BladeEnc.dll and BladeEnc.exe:

• Sourcecode available under the LGPL-license!
• 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.

Features specific to 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.

Features specific to 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).
• Full support for pipes and redirection (stdin and stdout).
• Textbased configuration file where you can change default settings.
