Does EAC add aguments to --alt-preset standard

I strongly doubt that, if the extra settings were taken into account by the encoder, you'd get the exact same file sizes on different settings. Probably, I was wrong with my earlier statement. I'm sure EAC will append its settings to the command line when not set to "user defined". As you quoted, rohangc, andre wiethoff confirms this. But, seeing your results, I now believe Lame simply doesn't do anything with those parameters when it sees --aps among the switches (as Pio2001 said above here). The constant file size with changing md5 implies that some fixed length thing differs among the files. Lame header? You can check most easily by decoding to wav and see if the wavs have the same md5. Or, you could strip the Lame headers, then check md5. 1. I loaded up Winamp 2.81, fired up the output plugin "Nullsoft Disk Writer plug-in v2.0c" and configured it to write the files in "PCM 44,100 KHz, 16 Bit Stereo". All other boxes in that window were un-checked. I hope what I've done here is right. 2. I added the 7 encoded versions of each track to the playlist and hit the "Play" button. I saved the decoded files into folders named "Track 01-Decoded", "Track 02-Decoded", etc. 3. I created .MD5 files for each such directory containing decoded files of the same song. The .MD5 files are shown below.Track 01 ; Generated by Easy MD5 Creator 1.4.0 on 21 February 2003 at 1:45:07 PM. ; ; File Size (Bytes) Time/Date ; ------------------------------------ ------------ --------- ; 001_256Kbps-User Defined Encoder.wav 65,604,140 13:41:27 21/02/2003 ; 002_32Kbps-User Defined Encoder.wav 65,604,140 13:41:45 21/02/2003 ; 003_CBR-256Kbps-Lame MP3 Encoder.wav 65,604,140 13:42:01 21/02/2003 ; 004_CBR-96Kbps-Lame MP3 Encoder.wav 65,604,140 13:42:19 21/02/2003 ; 005_DirectLame.wav 65,604,140 13:42:36 21/02/2003 ; 006_VBR-192Kbps-LAME MP3 Encoder.wav 65,604,140 13:42:54 21/02/2003 ; 007_VBR-96Kbps-LAME MP3 Encoder.wav 65,604,140 13:43:11 21/02/2003 ; 001_256Kbps-User Defined Encoder.wav 249D7B2FB73C508656DD5DC80329E612 002_32Kbps-User Defined Encoder.wav 249D7B2FB73C508656DD5DC80329E612 003_CBR-256Kbps-Lame MP3 Encoder.wav 249D7B2FB73C508656DD5DC80329E612 004_CBR-96Kbps-Lame MP3 Encoder.wav 249D7B2FB73C508656DD5DC80329E612 005_DirectLame.wav 249D7B2FB73C508656DD5DC80329E612 006_VBR-192Kbps-LAME MP3 Encoder.wav 249D7B2FB73C508656DD5DC80329E612 007_VBR-96Kbps-LAME MP3 Encoder.wav 249D7B2FB73C508656DD5DC80329E612 ; End of MD5 file.

Conclusion: ---------- The results are what we hoped they would be!!!!!!!!!!!!! The decoded files are identical to the last bit. Folks, Patsoe was right. Let's open that bottle of champagne and celebrate!!!! I guess the reason why the actual MP3 files were not identical was that they had additional information (LAME headers) written onto them. Otherwise, "--alt-preset standard" is "--alt-preset standard", no matter which "Parameter Passing Scheme" you use. I hope this has finally answered our question and brings an end to this traumatic discussion. Thanks a lot for your patience folks. I love you all and I love this forum. Bye. Let me just get a understanding here. Basically what your saying is, there is no difference, when you encode and Mp3's with EAC or RazorLame? As long as you have then configured correctly, too?

I always thought that there were no differences, when encoding with either, altought i only use RazorLame to encode my .wav's.
