Steps on how to convert MP3 to FLAC:

1. Add the media files to convert.

The first step is to select media files to convert. Run Audio Transcoder and use Folder Explorer to browse files you want to convert. Then select a file in the File List, drag it to the Drop Zone and drop it there. Optionally, Audio Converter allows you to edit tags of any selected file in Drop Zone.

Once files are selected, the next step is to select the output settings in Converter.

2. Select the output settings.

The second step is to select an output settings. To begin, select a folder for output and choose an action to be executed if an output file already exists (create a new file, overwrite or skip existing file).

Also you can set Media Converter to delete source file after conversion and preserve original folder structure, when doing batch conversion. Finally, you should select the output format and sound quality. In FLAC dialog box, choose format settings for the final tracks. Depending on quality you need, select bitrate, sample rate and the number of channels. You will probably lose some audio content if you choose mono option. You can choose what sample rate you want to use. 44.1 kHz (or 44100 Hz) is a sample rate used by music CDs. Less than that and you'll start to hear the loss in quality. You can choose a bit rate you want to use.

Once output settings are customized, you can go to the final step - transcoding.

3. Start to convert any audio files to .flac

Click Convert button to start to transcode music into any audio format you desired. A conversion dialog will appear to show the progress of data conversion. If you want to stop process, please click Stop button. After conversion, you can click an Output Folder button to get transcoded files and transfer to your iPod, iPad, iPhone, media player or hard driver.

During the turning music into flac, you can change priority of the process or set an automatic event to be executed when the conversion is over. After the conversion has finished, you can find your converted files in the output folder you specified.

Q: What is MP3 ?

A: MPEG-1 Audio Layer 3 or MPEG-2 Audio Layer III, more commonly referred in as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. Its lossy algorithm was developed in 1991. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. MP3 is an audio-specific format that was designed by the Moving Picture Experts Group (MPEG) as part of its MPEG-1 standard and later extended in the MPEG-2 standard. It is a method in store good quality audio into small files by using psycho-acoustics in order in get rid of the data from the audio that most of the humans can't hear.

Q: What is FLAC ?

A: FLAC stands for Free Lossless Audio Codec, an audio format similar in MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar in how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file. Notable features of FLAC: Lossless: The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical in what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an MD5 signature of the original unencoded audio data in the file header, which can be compared against later during decoding or testing. Fast: FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware. Hardware support: FLAC is supported by dozens of consumer electronic devices, from portable players, in home stereo equipment, in car stereo. Flexible metadata: FLAC's metadata system supports tags, cover art, seek tables, and cue sheets.
