MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. When set to 100%, the volume will not change.What is an MP3 (MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) file? Using the Volume slider you can adjust the sound level in the resulting MP3 file.
Parameters Sampling frequency and Channels (the number of audio channels in the output file) is best left in the positions Auto, then the program automatically selects the appropriate values. With this setting, the sound quality loss will be very small, and the size of the generated MP3 file should be significantly smaller than the source FLAC file. The highest value for the bitrate parameter is 320 kbit/s. If you set audio bitrate in the Auto position, the default bitrate will be used (192 kbit/s). Recommended bitrate values are 192-320 kbit/s. If you have such player, you must select CBR at the Bitrate mode list, then select desired audio bitrate value from the Bitrate list. Unfortunately, some older MP3 players support only MP3 files encoded at a constant bitrate - CBR. If you use one of the LAME presets, VBR (variable bitrate) compression is applied. By default the program will use the Standard LAME preset, which is a good compromise between sound quality and file size. You can select desired bitrate value from the Bitrate list or you can choose one of the predefined LAME settings (presets). This parameter determines the quality of the sound that will be saved in MP3 files. The next step is to select the desired bitrate of MP3 files. When you add FLAC files to the list, the next step is to set the output format to MP3 in the Audio section. More information on FLAC compression can be found at and Wikipedia.
#CONVERT FLAC TO MP3 PROGRAM PORTABLE#
MP3 is currently the most popular audio compression format, supported by almost every software and portable players and most new fixed players.
#CONVERT FLAC TO MP3 PROGRAM FREE#
However, if your player does not support FLAC, or you have a limited amount of free space in the memory (hard disk, SD card, etc.), then the best solution is to convert FLAC files to MP3 format. by ripping Audio CD using Exact Audio Copy or another ripper that supports FLAC compression, or by converting audio files to FLAC using Pazera Free Audio Extractor or other audio converter.įLAC files can be played using almost any modern software player (eg VLC, MPlayer), also more and more fixed and portable players supports FLAC compression. You can also easily create your own FLAC files, eg. FLAC compression reduces the file size by about 40-60% compared to the starting material, while lossy audio compressors (such as MP3, WMA, AAC) usually achieve much higher compression ratio (up to 90%), and with appropriately selected compression parameters the loss of sound quality will be very small.įLAC files are very common on the Internet: many music services provides the songs stored in FLAC files, also in programs to exchange files over P2P ( peer-to-peer) you can find a large number of such files. Unfortunately, this solution also has its weaknesses - FLAC files are relatively large. Therefore FLAC files are great for archiving audio CDs. After decompressing such files is obtained the original audio stream, so quality of audio is exactly the same as in the source material. FLAC ( Free Lossless Audio Codec) is a very popular codec for lossless audio compression used in audio files with the.
