Title: Selected bitrate differences
Post by: medex on 2010-05-18 19:05:54
Upon seeing the log output of some Exact Audio Copy flac rips.  I noticed that the Selected Bitrates differs.  As an example here is one from a Tool Rip

Quote
Exact Audio Copy V0.99 prebeta 5 from 4. May 2009

EAC extraction logfile from 10. November 2009, 11:05

Tool / Undertow

Used drive  : PIONEER DVD-RW  DVR-111D  Adapter: 0  ID: 1

Read mode              : Secure
Utilize accurate stream : Yes
Defeat audio cache      : Yes
Make use of C2 pointers : No

Read offset correction                      : 48
Overread into Lead-In and Lead-Out          : No
Fill up missing offset samples with silence : Yes
Delete leading and trailing silent blocks  : No
Null samples used in CRC calculations      : No
Used interface                              : Native Win32 interface for Win NT & 2000
Gap handling                                : Not detected, thus appended to previous track

Used output format              : User Defined Encoder
Selected bitrate                : 128 kBit/s
Quality                        : High
Add ID3 tag                    : No
Command line compressor        : C:\Program Files\FLAC\flac.exe
Additional command line options : -T "artist=%a" -T "title=%t" -T "album=%g" -T "date=%y" -T "tracknumber=%n" -T "genre=%m" -5 %s



As you can see the Selected bitrate is only 128 Kb/s, very low for a lossless audio file.  Is this still considered lossless?  Some other logs have very high bitrates, like 1024+ Kb/s.


So why the fluctuations and how much does this matter?
