This program is a front-end to two programs, l3enc/l3dec, a software only encoder/decoder pair. Users of this program need to have l3enc/l3dec v2.61 registered on their computer. Because of the intense encoding and decoding process, a pentium or better is recommended.
before the first use, be sure to adjust the options in the settings tab.
ENCODING
========
Make sure the encode radio button is selected. select a .wav file to encode using the drive, directory, and file boxes. For encoding, the input .wav files must have a resolution of 16bits. next, adjust the bitrate. here are some examples of bitrate use:
SOUND QUALITY BANDWIDTH MODE BITRATE REDUCTION RATIO
"telephone sound" 2.5 kHz mono 8 kbps 96:1
"better than shortwave" 4.5 kHz mono 16 kbps 48:1
"better than AM radio" 7.5 kHz mono 32 kbps 24:1
"similar to FM radio" 11 kHz stereo 56..64 kbps 26..24:1
"near-CD" 15 kHz stereo 96 kbps 16:1
"CD" > 15 kHz stereo 112..128 kbps 14..12:1
next, select the various check-box options:
DownMix -- converts stereo .wav files to mono
CRC check -- checks CRC of resulting .mp3 file
High Quality -- highest quality .mp3 output with encoding speed reduction
AutoDelete -- Delete original .wav after converting
finally, press the 'do it' button. your .wav file will be translated into an .mp3
DECODING
========
Make sure the decode radio button is selected. select the .mp3 file to decode using the drive, directory, and file boxes. Press the 'do it' button. your .mp3 file will be translated into a .wav
