Title: Flac lossless level
Post by: juanpmar on October 30, 2012, 01:31:01 pm
Hi there,

What´s the lossless level do you use with dBpoweramp?. So far I´m using the default one (5) but I wonder if you have found some issues using higher compression levels.

From the illustrate web site:

"Compression affects how much effort goes into compressing the audio, all compression modes give the same decoded audio (it is lossless after all), the higher compression levels will give a small % file size saving, but will require more time to compress and decompress. Compression Level 0 requires the least compression time, whilst Compression Level 8 the most."

There are 9 levels

-compression-level-0       set compression levels (0 worst, 8 best, 5 default)
-compression-level-1
-compression-level-2
-compression-level-3
-compression-level-4
-compression-level-5       (default)
-compression-level-6
-compression-level-7
-compression-level-8
-lossless uncompressed (?). (it seems redundant to me, is it the same as using a wav file?).

Do you use the verify option? (verifies compressed audio by reading back from hard disk).

IIRC XXHighEnd uses Level 6 by standard (in the Copy to FLAC functionality). To me this seemed the most efficient option (regarding the time it consumes and what will be achieved for compression factor).

For adding Embedded Coverart perhaps ?

XXHighEnd itself does not. Looks stupid to me anyway (I'm not veryfying my Word documents either). However, there's another kind of check which will fail when something went wrong at the encoding. Maybe that is what you mean (this is not part of standard FLAC and is an external program).

Thanks Peter,

I´ll try that 6 level in dBpoweramp also.

I wasn´t using the verify option anyway  :)
