What is a FLAC file?
FLAC — lossless compressed audio
Use the format FLAC
A concrete example
Prepare an MP3 copy for the phone while keeping the FLAC for archiving.
Useful checks
The MP3 output is lossy. Listen to complex passages and keep the original FLAC.
Choose a conversion
Keep the original and open the result in the software or on the device that will need to use it.
Your questions about this format
Which format should you choose to share a recording?
MP3 is a good starting point for sending or casual listening. Select your source, then MP3, start the conversion, and listen to the result. For audio editing, WAV may be more suitable but often produces a larger file.
Does converting an MP3 to a WAV improve the sound?
No: the WAV does not restore the information lost when creating the MP3. It mainly allows you to change the working format. To preserve the maximum quality, start from the original recording when you have it.
How can you compare before downloading?
After a successful audio conversion, use the original and resulting players. Check a quiet area and a loud area, then the beginning and the end. In case of cutoff or absence of sound, keep the original and report the formats used to support.
Why doesn't a MIDI file sound exactly like it does on my system?
A MIDI describes notes and instruments, not a sound recording. Its conversion depends on the sound bank used by the engine. Listen to the rendering before broadcasting; the MIDI synthesis is part of specialized NoLimit processing.
What is it?
FLAC compresses audio without discarding a single piece of information. It roughly halves the file size, and the decompressed file is rigorously identical to the original — bit for bit.
It works on the same principle as a ZIP archive: it shrinks the file by identifying redundancies, never throwing anything away. This is nothing like MP3, which permanently discards data.
History & origin
FLAC was released in 2001 by Josh Coalson, then taken over by the Xiph.Org Foundation, which turned it into a fully free, patent-free format.
It became the format of choice among audiophiles and high-resolution music platforms, drawn by the promise of perfect quality without the bulk of WAV.
Why it is useful
Zero loss, half the file size, and rich metadata support — title, artist, cover art, lyrics — none of which WAV can carry.
A free, open format supported by nearly every modern player.
Limits & drawbacks
It remains far heavier than MP3: five to ten times larger, for a difference that very few ears can actually detect in everyday listening.
Apple devices don't support it natively, favoring their own lossless format instead.
Practical tips
FLAC is the ideal format for archiving a music collection: you keep the full quality and can always derive MP3s from it later.
For listening on the go, convert your FLAC files to MP3 or AAC: you'll save considerable space with no audible difference on public transport.
