LAME MP3 Encoder 3.99.5
CBR compression mode
The CBR method can be used if you want to keep a constant bitrate all over the audio file and get a predictable size of the output file.
You should use this only if you need to maintain compatibility with streaming applications and hardware-based decoders that only support this compression type, otherwise it's not advisable due to the large size of the output file.
VBR compression algorithm
The VBR method is the most commonly used encoding type and it can compress files keeping a user-defined quality level instead of a bitrate, thus allowing LAME MP3 Encoder to dynamically change bitrate depending on the complexity of the audio file. Use the Variable Bitrate method to get the smallest size for encoded files while keeping the desired quality.
ABR compression method
And finally the ABR method, which is a combination between the above mentioned and offers encoding capabilities using the smallest possible bitrate needed to encode the file while keeping the bitrate relatively to the user defined value. Use this to get a smaller-sized MP3 file than the CBR encoding method offers and still preserve the bitrate to a desired target.
The application uses the command-line interface to encode audio files so make sure you read the information in the package or the Command Line Help before getting to work. The commands are quite simple and use the following pattern: lame [options] [outputfile], where options refer to the encoding method and bitrate or quality.
LAME MP3 Encoder also enables you to adjust input and operational options, noise sharpening and psycho acoustic algorithms, filter options, verbosity, ID3 tag information or MP3 header and stream options.
So if you are a professional audio encoder, LAME MP3 Encoder offers you the tools you need to compress audio files and still keep the quality you are comfortable with. All you need is a little patience to get a notion of the commands you have to use.
