FLAC Decompression

Hello Everybody,

I have a few FLACs which I want to losslessy decompress to WAV files. Therefore I was recommended to use dbPoweramp.
I tried the tool once and so far it is pretty convenient to use but there are two things Iíve noticed.

First during the converting process, the tool says a re-encode takes place. As I understood, re-encoding a lossless codec (like flac and wav) the quality will remain the same, is this correct?
Also, is dbPoweramp a good choice for my desired task ?

Second, every wav file i checked has had the same Bitrate (2117 Kb/s) and of course the same bit depth of 24 Bit. I just want to be sure if this is normal.

Thank you

I suppose that "re-encode" in this context means simply de-compressing flac to wav in which case quality will remain the same. I never used dbPoweramp but I guess it's a safe assumption.

To each his own. If it works for you, use it. I personally use batch files with the command line flac encoder to compress/de-compress. There are also countless other "GUIs" that will perform the same task. I highly recommend foobar2000.

It's normal since standard wav bitrate is the product of bit depth, sample rate and number of channels.

Groucho2004 answers are all correct.

You don't need pay 58Ä for dbPoweramp when the flac codec is free soft.

You can use foobar2000 for free, and one of the best player and audio management, like Groucho2004 say.

Or batch files with the original, and actualized, flac.exe soft:
FLAC v.1.3.3.git-ce6dd6b5 win64/32 bundle

With a decode.bat in a folder with flac.exe and the *.flac to convert:
Quote:
FOR %%I in (*.flac) DO flac.exe "%%I" -o "%%~nI.wav"
Or if you have already ffmpeg.exe
Quote:
FOR %%I in (*.flac) DO ffmpeg.exe -i "%%I" "%%~nI.wav"

For anyone who needs a GUI, LameXP also does the job well

I wasn't even aware that you have to pay for this software.
