My FLAC has lower bitrate than its lossless source—why/which is right?

Hello has all

I am French my English is a little rusty

I am going to explain you my problem, as you I am a faithful user of foobar 1.1.10

I listen a lot of classical music

Mainly in the .flac format

I have to notice that the bitrate of foobar is 667 kbps for dvorak synphonie numero 1

The mediainfo software indicates me kbps 667 kbps

Dbpoweramp indicates me kbps 1411

I obtain these results of a classic release of quality but I ask the question what bitrate is exact?

You will can can be to answer my question

"Dbpoweramp indicates me kbps 1411 "

This is the bitrate of the decoded flac file, ie., the native bitrate of the wavefile.

The bitrate foobar is indicating is the bitrate of the compressed flac file.

Lossless audio compression does just that: compresses. Therefore a decreased bitrate in a lossless format such as FLAC is not only expected but essential.

1411 kbps is the bitrate of the uncompressed audio. The FLAC will be decompressed to exactly the same bitrate and exactly the same audio (by definition of the word lossless).

filesize / duration = bitrate

Thank you for your answers

All right to summarize

Say I if I make a mistake

Foobar indicates me 667 kbps because it is to compress it .flac

Once to unwind will be 1411 well kbps Quality audio CD of the business

Thus a release 1:1 maximum Quality for a release of an audio cd

If I burn it on a cd the bitrate will be good of 1411 kbps ?

Yes: the entire purpose of lossless audio compression is to reduce the file size/bitrate needed to store the input signal, whilst preserving it exactly.

Yes again.
