Anyway, I've just been testing eac3to with libFLAC 1.2.1 and I'm not getting any significant filesize differences. I've tried three different movie soundtracks, all 5.1, one 16 bit and two 24 bit. I wonder what's different about your test files, raquete and tebasuna51, that produces such dramatic differences? I'm going to stick with 1.2.1 for the time being anyway and I'll report back if I hit any problems. |

http://forum.doom9.org/showpost.php?...5&postcount=12 now after change to libFLAC 1.2.1 the results are equals. later i will post the result of wave source 5.1 24b/96k with 1:08:00:928 with the "old" and with the "new" libFLAC in eac3to...i still don't know the wave file size, are in seperateds channels(L,R,C...etc) and i need to join(encode) as multichannel. |

kypec,
sorry, I 've read it but somehow I've mixed it in my mind with some other previous posts. I've already deleted that post because is completelly nonsense. By the way, thanks for your findings. I will also try with new libflac, maybe I can gain some extra space on my backups. |

2) RaWavSource function is in NicAudio.dll v2.0. Downnload (see my signature) and put in AviSynth plugins folder

Are you sure you weren't using the «lossy» compression mode ? Also, if the answer is "yes", are you sure the sound editors you used were decompressing the lossless .WV files correctly??? Last edited by Midzuki; 25th August 2009 at 15:12. Reason: fix typo |

first, thanks for the link. i really don't know TTA and need to read about this format. WV lossy? i don't knew that one lossless compression can be "lossy". adjusted "lossless(high)" to encode (no hibrid) 32 bit float and adobe audition to open and check WV. example from audition waveform statistics (selected one channel where have one clip): Code:
Mono Min Sample Value: 21785 Max Sample Value: 32767 Peak Amplitude: -13.87 dB Possibly Clipped: 1 DC Offset: 79.736 Minimum RMS Power: 996.99 dB Maximum RMS Power: -inf dB Average RMS Power: -3.01 dB Total RMS Power: -18.65 dB Actual Bit Depth: 16 Bits Using RMS Window of 50 ms |

tebasuna51,
after 8 minutes with ~60% of the file encoded i got this message: Error: System.IO.IOException: O pipe foi finalizado. Code:

No, it's not undocumented. FLAC has very extensive support of tagging, look in the documentation, --help switch is your friend.

435 306 274 : 435 640 726 = 99.923%, the real difference is less than 0.1%, no big deal. |

Maybe in next v1.2.2... See: http://sourceforge.net/tracker/index...78&atid=363478 http://sourceforge.net/tracker2/?fun...78&atid=113478 Until next flac.exe version you must use only eac3to if flac file output is >2GB. Edit: With an audio track tested don't exist many difference: 8032850564 Pulp.wav 3918536382 Pulp_120.flac 48.8% 3893160387 Pulp_121.flac 48.5%

I don't use Adobe Audition, so I can just suppose it doesn't deal very well with 32-bit .WV files... BTW: Did you generate those 32-bit .WV archives from 32-bit sources --- or not ??? I mean: regardless of the possible bugs/imperfections of «WavPack.exe», I see no point in creating 32-bit .WV archives only because Adobe Audition is your favorite sound editor.

audition always open as wave 32bit float but i don't remember if i generate those 32-bit WavPack archives from 32-bit sources ...i don't use WV no more after see that clips. sound forge show exactly the same clips as audition but audition is my favorite, have amazing differents features. i'm using now flacs or apes. flac is my preference. cheers! |

I've tested with Baraka, the biggest movie audio file I have, 5.1 96kHz 24bit.
wav : 9,452,814,404 1.2.0: 5,279,451,099 (55.85%) 1.2.1: 5,247,885,754 (55.51%) That's not a very big difference. I'm not sure it's worth the effort to reencode all my backups with 1.2.1, I think I will only use it with the new ones... |

I just included one of that tags manually in order to obtain one FLAC file as closely similar to another one as possible for testing purposes. |
